Abstract
The coating based on a composite mixture of 50Ti-50HA (mass, %) was obtained by detonation spraying. The rational model of detonation spraying and the composition of the 50Ti-50HA mechanocomposite (mass, %) were determined experimentally way. The surface M orphology, phase and element composition of coatings were st udied by scanning electron microscopy, energy -dispersion analysis, x-ray diffractometer, and Raman spectroscopy. The results of the elemental analysis showed the formation of a composite coating with HA content with a Ca/P=1.53 ratio, close to the indicator of bone tissue. Based on the results of Raman spectroscopy and x-ray phase analysis, it can be said that HA and titanium correct the harmonious composite component.
