Biocompatibility of thin layers

R. 7, nr 35-36

Medical tools for minimally invasive surgery are often used in hard environmental conditions. For more effective protection against corrosion of the substrates, caused by steam sterilization loadings, TiN, TiCN, TiAlN, ZrN PVD - layers were used. All of the considered PVD - coatings have shown a sufficient sterilization resistance and the necessary biotolerance, which is required by the legislator for short-term applications of tools. The biocompatibility was estimated by monitoring and evaluating the growth of certain animal cell cultures. Steam sterilization was performed in an autoclave by the sterilization pressure 105KPa in 60 cycles.
