Multilayer Hf-Ti-N Nanocomposites for Medical Purposes

The enhancement of the biocompatibility of materials for orthopedics and traumatology was studied through plasma-phase condensation of coatings based on titanium-hafnium nitrides. Thin-film multilayer coatings made from nanoscale layers of hafnium and titanium nitrides are resistant to sterilization, prevent the release of toxic ions, have a corrosion rate of up to 5 × 10^–15 mol/(cm² h), and possess bacteriostatic properties. A coating condensation technology was developed in a nitrogen environment for leather material. The properties of the coating are formed by the impact of low-energy ions on the structure.
