  • Long-term titanium implants with bioactive ceramic coating
    Długoterminowe implanty tytanowe z bioaktywną powłoką ceramiczną
    Project manager: Alicja Kazek-Kęsik
    Project supervisor: Wojciech Simka
    Funding source: National Science Centre & The National Centre for Research and Development
    Programme: Tango
    Project no.: TBD
    Realization period: 2019–2020

    Bioimplants made from titanium for the long-term applications are getting more and more interest both in the academic and the industrial sectors with each year’s passing. They are typically applied for treating bone or dental fractures in the case of both humans and animals. A specifically designed ceramic layer that can be coated onto a titanium implant usually improves its bioactivity which in turn improves the osteointegration of the whole system. By shortening the time need for the bone ingrowth and healing is beneficial for the patients and it reduces the risk of the development of septic infections. It is possible to apply plasma electrolytic oxidation coupled with the sol-gel method to produce such coatings on the commercially available titanium implants.

    The aim of the project will be to adjust the surface processing parameters to obtain satisfactory products, starting from titanium implant materials. It is planned to investigate the physicochemical properties of the coated implants as well as to identify the biological response of the new surfaces. Lastly, the “K” phase of the project will involve procuring potential customers for the novel implantation system.

  • New generation of bacteriostatic/antibacterial coatings dedicated to hard tissue, obtained by PEO method in suspensions containing silver, copper and zinc compounds

    Project manager: Katarzyna Leśniak
    Project supervisor: Wojciech Simka
    Funding source: The Ministry of Science and Higher Education
    Programme: Diamond Grant
    Project no.: 0068/DIA/2018/47
    Realization period: 2018–2022

    The aim of the project is to obtain porous oxide layers containing silver, copper and/or zinc compounds on the surface of selected titanium alloys. As a result, it is expected to obtain antibacterial and cytocompatible surfaces of titanium materials. Because of increasing resistance of bacteria to antibiotics, it is important to develop procedures for the preparation of materials with antibacterial properties resulting from the action of agents other than antibiotics.

    In order to obtain antibacterial/bacteriostatic layers, surfaces of titanium alloys will be anodically oxidized in suspensions of bioactive chemical compounds containing calcium, phosphorus and compounds with antibacterial properties, e.g.: phosphates or oxides of silver, copper and zinc. In the project it has been planned that the surface modifications of titanium alloys: Ti-6Al-4V, Ti-15Mo, Ti-2Ta-3Zr-36Nb, Ti-13Nb-13Zr will be carried out.

To supplement the received data a literature-based clinical assessment will be conducted to grant the manufacturer with a suitable certificate. After the finalization of the project, the dental implants production technology will be implemented in Osteoplant R&D and the innovative product will become available in the market.

  • Modulation of properties of oxide coatings on aluminium and its alloys by plasma electrolytic oxidation method in solutions containing organic compounds
    Modulacja właściwości warstw tlenkowych na aluminium i jego stopach metodą plazmowego utleniania elektrochemicznego w roztworach zawierających związki organiczne
    Project manager: Maciej Sowa
    Project supervisor: Wojciech Simka
    Funding source: National Science Centre
    Programme: Preludium
    Project no.: 2016/23/N/ST5/02022
    Realization period: 2017–2020

    Aluminium and its alloys are members of the group of construction materials. It is vital to properly modulate the physicochemical state of the surface of a given material prior to its application. Among myriad of surface modification techniques which one can note plasma electrolytic oxidation (PEO). It can be observed that recently many researchers show interest in so-called ‘smart’ PEO coatings, i.e. coatings that in the event of developing cracks or pores release corrosion inhibitors that counteract the occurrence of localized corrosion. Therefore, the scientific aim of the present project is a) to describe the formation mechanism of oxide layers on aluminium and its alloys by plasma electrolytic oxidation in solutions containing organic compounds, which would improve corrosion resistance of the underlying metal and b) to determine the effect of treatment parameters on properties of the resulting coatings, especially concerning their ability to ‘self-heal’.

  • Fast degradable polymeric coatings on electrochemically modified long-term implant surface
    Szybko degradujące warstwy polimerowe na modyfikowanej elektrochemicznie powierzchni implantów długoterminowych
    Project manager: Alicja Kazek-Kęsik
    Funding source: National Science Centre
    Programme: Sonata
    Project no.: 2016/21/D/ST5/01652
    Realization period: 2017–2020

    To date, many investigators studied titanium alloys surface functionalization, with a potential use in dental implants manufacture. Ti-xMo, Ti-xNb-xZr-xTa alloys are considered as future dental materials, mainly because they are composed of biocompatible compounds and exhibit mechanical properties that resemble human bone tissue. Physicochemical properties and corrosion resistance of these Ti alloys are much better compared to titanium and Ti-6Al-4V alloy, which are widely used in medicine. One of the techniques for surface modification is anodizing. PEO is a variant of anodic oxidation which produces porous oxide layer on top of a metallic workpiece. The layer enhances integration between material and bone tissue. In course of the treatment some of electrolytic solution’s components may be incorporated in the structure of the oxide coating. Surface morphology of the porous oxide is also favorable for osteoblasts adhesion and proliferation. Beside many advantages of PEO bioactive substances, such as drugs, are not expected to be introduced into the oxide layers structure, because of the destructive nature of surface micro discharges, which are observed during the treatment. The presence of these substances on the activated impant’s surface is important due to the possibility of post implantation infection. Septic infections are one of the reasons for bone implants failure.

    The aim of the project is formation of porous oxide layer and top fast degradable polymer layer with biologically active substance on novel titanium alloys surface. The oxide polymer layer will be formed on the Ti-xMo and Ti-xNb-xZr-xTa alloy surface by plasma electrolytic oxidation. Then the fast degradable polymer layer with drugs will be deposited via dip coating. It is expected that the drugs will be released into the organism up to 4 weeks after exposition into physiological solutions. Formation of biohybrid layers loaded with drugs will be an innovative way for the titanium alloys surface modifications. Basic physicochemical and electrochemical properties of the obtained materials will be determined in course of this project.

  • Surface biomodification of vanadium-free medical titanium alloys
    Biomodyfikacja powierzchni medycznych bezwanadowych stopów tytanu
    Project manager: Alicja Kazek-Kęsik
    Funding source: National Science Centre
    Programme: Preludium
    Project no.: 2013/09/N/ST5/00867
    Realization period: 2014–2017

    Titanium and its alloys, as metallic biomaterials, have shown relatively good biological tolerance by the human organism. Currently Ti-6Al-4V alloy is the most frequently applied of the Ti alloys used in medical applications. However, presence of carcinogenic vanadium and its pentavalent oxide, which can dissolve into blood, have driven the scientific community do devise alloys which are vanadium-free (e.g. Ti-13Nb-13Zr, Ti-6Al-7Nb or Ti-15Mo). Surface modification of biomaterials is necessary to tune the physicochemical state of the surface to suit the strict requirements in the implantation region. Electrochemical techniques are excellent for such purposes and in this project an explanation of the mechanism of protein adsorption on a modified medical, vanadium-free titanium alloy surface will proposed. At first the surface of a vanadium-free titanium alloy will be modified by plasma electrolytic oxidation. Then a ceramic layer will be formed by electrophoretic deposition or by sol-gel method on top of the oxide layer. Consequently the projected is aimed at obtaining a multilayer coating on titanium alloys surfaces with the adsorbed proteins at the top.

  • Investigations on formation chromium-free conversion coatings on galvanic Zn-Co alloy coatings by anodic oxidation method
    Badania nad wytwarzaniem bezchromianowych powłok konwersyjnych metodą utleniania anodowego na galwanicznych powłokach stopowych Zn-Co
    Project manager: Artur Maciej
    Funding source: National Science Centre
    Programme: Sonata
    Project no.: 2013/09/D/ST8/04005
    Realization period: 2014–2017

    Zinc-based alloy coatings are considered to be one of the most effective anodic coatings used for corrosion protection of steel elements . There are mainly Zn-Ni, Zn-Co and Zn-Fe coatings, which for the sake of the necessity of elemination of the toxic cadmium coatings from use, are more often used in many branches of industry. In order to improve the corrosion properties of zinc-based alloy coatings, the formation of conversion coatings on their surface is usually realized. One of the most effective, most popular and up to date most often used are the toxic chromate conversion coatings (CCCs). Anodic passivation of the surface of the zinc-based alloy anticorrosion coatings may prove to be successful in corrosion sealing of the underlying material. The scientific aim of the project is to determine the mechanism of formation of conversion coatings on the surface of Zn-Co alloy galvanic coatings by anodic oxidation in aqueous and non-aqueous solutions and the mechanism of corrosion of the coatings in different corrosion environments.

  • Investigations of chromate-free conversion coatings formation by anodic oxidation of galvanically-formed Zn-Ni alloy coatings
    Badania nad wytwarzaniem bezchromianowych powłok konwersyjnych metodą utleniania anodowego na galwanicznych powłokach stopowych Zn-Ni

    Programme: Lider
    Project no.: LIDER/009/433/L-4/12/NCBR/2013
    Realization period: 2014–2016

    In recent years, many domestic and European legislative documents prohibiting or limiting application of cadmium and chromium(VI) compounds have come into force. The restrictions force the industry to discontinue using the cadmium coatings as well as chromate conversion coatings (CCCs) and to replace them by other means providing similar anti-corrosion properties. The alternative may be the galvanic Zn-Ni alloy coatings with chromium-free conversion coating formed through anodic oxidation process. The coatings obtained in such a way will be an excellent replacement of Cd- and Cr-containg coatings for protection of steel elements and they will fulfil the requirements stated by the recipients of many essential branches of industry. The scientific aim of this project will be determination of the influence of anodic oxidation parameters on the properties of the conversion coatings obtained during the process, formed on galvanic Zn-Ni alloys as well as proposal of the formation mechanism of such coatings.

    The project is concerned with PEO (Plasma Electrolytic Oxidation) surface treatment of potentially interesting, biocompatible metals: zirconium, niobium and tantalum. Via this method it is possible to modify metallic surfaces in terms of their surface morphology (enhanced specific surface area and appearance of crater-like features), composition (incorporation of calcium and phosphorus compounds) and corrosion resistance in physiological conditions. Bioactivity of the functionalized metals’ surfaces will be assessed with the use of mesenchymal stem cell cultures.

    New generation of titanium alloys for medicine contain beta-stabilizing element, such as niobium, tantalum and zirconium. Beta Ti phase is responsible, among others, for lower modulus of elasticity, which is desirable for bone implants. These metals on their own are characterized by superior biocompatibility, which gave an incentive to investigate how plasma electrolytic oxidation of these metals will influence their bioactivity. The aim of this project was to gain knowledge about the mechanism of anodic oxidation of Nb, Ta and Zr as well as to characterize the obtained oxide layers in terms of their physicochemical, electrochemical and biological properties.

    One of modern titanium alloys used in medicine, particularly as a material for bone and dental implants, contain vanadium (Ti-6Al-4V). However, vanadium metal and its oxidized form were shown to exhibit cytotoxic properties and therefore alternative alloy additives for medical titanium alloys are sought. In this project electrochemical surface modification was applied to alter surface properties of vanadium-free titanium alloys: Ti-13Nb-13Zr, Ti-6Al-7Nb and Ti-15Mo. Silicate-based solutions were thouroughly investigated as electrochemical baths for plasma electrolytic oxidation (PEO) process of aluminium, aluminium alloys, etc. However, not much interest was given to titanium alloys modifications by PEO in Si-containing solutions and possible effects of such modification on surface bioactivity towards osseointegration were to be surveyed.
