Bioactive multilayer coatings that initiate bone growth: structure and properties

The composition of a multilayer coating on the basis of Mg + Ca + P$_2$O$_5$ applied to the surface of the intramedullary implant in order to initiate bone tissue growth has been proposed and substantiated. It is shown that the Mg + Ca + Ethidronate + P$_2$O$_5$ + Zn + P$_2$O$_5$ multi-layer system, which was heat-treated at 200° C, has high resistance to abrasion. In SBF buffer solution the layer system is transformed into HA. Influence of heat treatment is manifested in increase of structural order of separate layers.
