Abstract
The invention relates to surface machining of medical purpose metals and their alloys and can be used for the production of implants for the replacement of damaged bone tissue fragments including, for example, orthopedic and dental implants, maxillofacial and spinal column surgery implants, artificial joints, clamps etc. The technical result achieved by the provided method is the provision of implants made from special medical purpose alloys with continuous bioactive coatings with antibacterial effect and high adhesion strength to substrate (critical load more than 100 N), high wear resistance and controlled roughness. The technical result is achieved as follows. The method of obtaining bioactive coatings with antibacterial effect comprises electrospark machining of the electrical conductive substrate surface with the processing electrode of the following compositions (wt.%): bioactive additive - 5-40, antibacterial metallic additive - 0.5-5, biocompatible additive of metal or a refractory compound - balance. Electrospark machining is carried out under the following conditions: 100≤N≤10000, 10≤f≤100000, 0,01≤v≤0.6, where Nis the power of a unit pulse discharge, W; f is the frequency of pulse discharges, Hz; v is the linear speed of the processing electrode, m/min.
