Objective
To improve biocompatibility and increase the durability of materials used in the biomedical field.
The objectives of this project are to improve biocompatibility and increase the durability of materials used in the biomedical field.
The first aspect to be explored is the resistance of stainless steel and copper chromium molybdenum orthopaedic implants in biological environments involving improvement of the superficial properties relative to fretting and to corrosion. Ion implantation will be performed with species acting on the tribological behaviour (titanium, carbon, nitrogen, silicon) and on the surface electrochemical properties (titanium, molybdenum, silicon, palladium).
Examination is also taking place of the tolerance of the tissues to the materials, using implantation of elements which make up the tissues and are suspected of inhibiting the biological reactions. 2 types of ions will be implanted: calcium, phosphorus and silicon to link ions enhancing the calcification in the case of orthopaedic implants, ions modifying hydrophilic characteristics and hydrophobic characteristics of the polymers surfaces: carbon, nitrogen, oxygen, silicon. These implantations will be followed by coatings of constituents such as bioglasses for the bone implants and proteins grafting for flexible materials.
Achievements to date involve the improvement of materials resistant to degradation bymetal metal interaction. Improvement in the tribological properties of metallic materials by nitrogen implantation is one of the first applications of this technique; it has been applied to titanium alloys and stainless steel in the biomedical field as well as in other fields. Moreover, significant improvements in corrosion resistance can be achieved by the implantation of other elements (chromium titanium molybdenum silicon palladium) used 1 by 1 or in combination, possibly including nitrogen.
Insertion of the materials in a biological medium metal bone interaction has occurred and a biodegradable osteoconductive bioglass has been developed and a feasibility study is under way , into polymer blood interaction.
These aspects will be explored:
1.The resistance of stainless steel and CoCrMo orthopaedic implants in biological environments with an improvement of the superficial properties relative to fretting and to corrosion. Ion implantation will be performed with species acting on the tribiological behaviour (Ti, C, N, Si) and on the surface electrochemical properties (Ti, Mo, Si, Pd).
2.The tolerance of the issues to the materials, using implantation of elements which make up the tissues and are suspected of inhibiting the biological reactions. Two types of ions will be implanted: Ca, P, Si to link ions enhancing the calcification in the case of orthopaedic implants, ions modifying hydrophillic/hydrophobic characteristics of the polymers surfaces: C, N, O, Si. These implantations will be followed by coatings of constituents such as bioglasses for the bone implants and proteins grafting for flexible materials.
