Due to unique physico-chemical properties and good biocompatibility are carbon layers considered to be promising material for wide field of biomedical applications. In this study, carbon films were manufactured in microwave and radio frequency plasma reactor using dual frequency method (MW/RF PCVD - microwave and ratio frequency plasma chemical deposition). Four various processes of deposition were used for preparation layers on substrates of medical stainless steel AISI 316 L. On samples of all four processes, growth and adhesion of cells were observed.

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.
