As a result of the 2nd stage the structure of coatings based on hydroxylapatite and influence of the properties of the porous substrate on them was investigated. The technology gas-detonattion deposition (GDD) of the coatings was completed. In order to optimize the technology and enable the deposition of coatings with defined and controlled properties the automation of the GDD setup was carried out. Test seriesof coatings from bioactive ceramic materials was deposited on developed and manufactured samples of porous silicon-carbide ceramics. Investigation of properties of porous substrates and bioactive coatings allowed to establish peculiarities of influence of substrate characteristics on the properties of coatings. Best options for formation of bioactive coatings with the best structural perfectionwere choosen. It was shown that the optimal quality of coatings achieved by the orientation of pores in silicon-carbide ceramics along the surface on which the deposited coating, which prevents the occurrence of through pores in the layer even at small thicknesses.
