FIELD: medicine.
SUBSTANCE: described is a method for producing bioactive coating with antibacterial effect, which includes electric spark processing of substrate surface processing electrode, following composition (wt%): bioactive additive - 5-40, antibacterial metal additive - 0.5-5, biocompatible metal - balance. Electric spark processing is performed at following modes: 100≤Ni≤10000, 10≤f≤100000, 0.01≤v≤0.6, where Ni - power of single pulse discharge, W, f is frequency of pulse discharges, Hz, v - linear speed of processing electrode, m/min.
EFFECT: technical result is obtaining implants made of special alloys for medical purposes, solid biocompatible, bioactive coating with antibacterial effect with high adhesion values (more than 100 N), high wear resistance and with a given relief.
