FIELD: medicine.
SUBSTANCE: method for nanoporous oxide formation on the surface of an implant from powdered niobium, comprising processing in an ultrasonic bath sequntially in acetone and ethanol, washing in distilled water, drying in air and anodizing in an aqueous solution of 1M H2SO4+1% HF in galvanostatic mode with a current density of 0.01 A/dm2 within one hour.
EFFECT: increased specific surface of the coating, increased coating wettability with water and saline, and maintained high corrosion resistance of implant in the bio-environments.
