METHOD FOR ELECTROPLASMA SPATTERING OF BIOCOMPATIBLE COATINGS BASED ON MAGNESIUM-CONTAINING TRICALCIUM PHOSPHATE Russian patent published in 2018 - IPC A61K6/33 A61L27/32 A61F2/28 B05D7/24 

FIELD: medicine.

SUBSTANCE: method includes implant surface preparation by air-powder abrasive treatment and ultrasonic degreasing, then electrolytic-plasma spattering of a titanium sublayer and biocompatible layer is performed, ultrasonic degreasing is carried out in an aqueous solution of surfactants at temperatures of up to 40°C for 5-7 min, electrolytic-plasma spattering of the titanium sublayer is done from the spraying distance of 120-150 mm for 12-15 s, at the plasma-forming gas flow rate of 20 l/min, particle size not exceeding 150 mcm and arc current of 350 A, electrolytic-plasma spraying of powder magnesium-containing tricalcium phosphate is done from the spraying distance of 50-60 mm for 10-12 s, at the plasma-forming gas flow rate of 20 l/min, dispersion of no more than 90 µm and arc current of 350 A.

EFFECT: invention can be used in maxillofacial surgery and traumatology for production of interstitial endoprostheses on a titanium base.
