METHOD OF OBTAINING COATING ON IMPLANTS FROM TITANIUM AND ITS ALLOYS Russian patent published in 2017 - IPC A61F2/02 C23C4/10 C23C4/18 

FIELD: metallurgy.

SUBSTANCE: invention relates to the production of microporous structures on the surface of articles made of titanium or its alloy and can be used in the field of medical engineering for the manufacture of surface-porous endoprostheses and implants for traumatology, orthopedics, various types of plastic surgery, for surface preparation from titanium and its alloys of titanium implants for applying bioactive coatings. The method involves laser treatment of a surface in an argon medium at a radiation power of 400-500 W and a predetermined velocity of the laser beam, simultaneously supplying titanium carbide powder to the irradiation zone, followed by etching in concentrated nitric acid for 3-7 days, washing with acid and drying at temperature of 50-100°C.

EFFECT: reducing the labor intensity of the method, increasing its industrial and environmental safety, increasing the specific surface area of the microporous coating formed, increasing uniformity in size and uniformity of pore distribution.
