FIELD: electroexplosive deposition.
SUBSTANCE: invention relates to a method for electroexplosive deposition of bioinert coatings based on molybdenum and niobium onto titanium alloy implants and can be used in medical technology, traumatology and orthopedics. An electric explosion of a two-layer composite electrically exploded conductor is carried out, one of the layers of which consists of molybdenum foil weighing 50-500 mg, and the second layer is made of niobium foil with a weight equal to 0.5-2.0 of the mass of the first layer. A pulsed multiphase plasma jet is formed from explosion products. The titanium alloy implant surfaces are melted at an absorbed power density of 1.5-1.8 GW/m2.
The explosion products are deposited on the surface and a bioinert coating based on molybdenum and niobium is formed on it.
EFFECT: surface layer is formed with high adhesion of the coating with a titanium alloy substrate, low roughness and homogenized structure, which has an antibacterial effect, which increases the service life of implants and expands the field of practical application.
