Antimicrobial properties of nanostructured plasma condensates from medical implants
Abstract
Thin film coatings of titanium nitrides and hafnium for implants were investigated. The HfN + TiN coatings were condensed from the plasma phase. Analysis of the structure and composition revealed multilayers of the coating, the composition of the layers, and the presence of columnar crystals. The coating thickness is 2-5 μm, with a characteristic size of grains 20-50 nm. Antimicrobial properties for staphylococcus and pseudomonas aeruginosa have been established, a technique for determining the antimicrobial properties of coatings has been demonstrated, and medical approbation of implants with a coating has been carried out.
