METHOD FOR PLASMA SPRAYING OF BIOCOMPATIBLE COATINGS BASED ON TRICALCIUM PHOSPHATE WITH ADDITIONAL ALLOYING ELEMENT Russian patent published in 2021 - IPC C23C4/04 C23C4/134 A61L27/32 A61K6/838 A61F2/28 

FIELD: plasma spraying on biocompatible graft surface.

SUBSTANCE: invention relates to a method of plasma spraying on the implant surface of a biocompatible coating based on manganese-containing tricalcium phosphate. Preliminary preparation of the implant surface is carried out by abrasive treatment. Then, the plasma deposition of the titanium sublayer is carried out from a deposition distance of 90-110 mm at a plasma forming gas flow rate of 45-60 l/min and an arc current of 400-450 A. Subsequent plasma sputtering of a biocompatible layer of a powder of manganese-containing tricalcium phosphate with a concentration of manganese of 3б weight percentage, is carried out from a spray distance of 90-110 mm at a plasma forming gas flow rate of 34-36 l/min and an arc current of 400-450 A.

EFFECT: coating with antibacterial properties is obtained through the use of manganese-containing tricalcium phosphate (Mn-TCP), used as a component of the plasma dust coating.
