Abstract
It is suggested using two-layer bio-cermet (titanium-hydroxyapatite) coatings for titanium alloy endoprostheses. A combination of porous titanium with an external hydroxyapatite (HA) layer provides high strength of adhesion of such coatings to the surfaces of endoprostheses (24-25 MPa) and subsequent active growth of bone tissue into them. The microplasma spraying technology allows formation of the HA layer with the 88-98 % content of the crystalline phase, thus providing a high degree of utilisation of the powder (up to 90 %) in spraying and increasing the cost effectiveness of the process.
