FIELD: medicine.
SUBSTANCE: bactericidal coating for medical devices consists of condensates formed by ion bombardment accompanying vacuum electric-arc evaporation of metals in the medium of reacting gas - nitrogen, on the basis of titanium nitride, and additionally contains hafnium nitride in the following proportions, wt %: Ti - 17-24, Hf - 70-80 and N - 3-6.
EFFECT: using the invention enables producing the coating for medical devices having a long-term contact to tissues of a living body; its durability and bacteriostatic properties prevent propagation of pathogenic microorganisms near the implant.
