| Резюме: | Title screen The studies of the effect of applied ultrasound (US) field with varied power of 35 W or 100 W during the micro-arc oxidation (MAO) process on the morphology, porous structure and adhesion strength of the calcium phosphate (CaP) coatings on the titanium surface have been performed. The transmittance of US field through the electrolyte during the MAO process led to the increase of the coating thickness from 50 to 60 [mu]m, roughness from 3 to 4.5 [mu]m and internal porosity from 27 to 41 %, and to the decrease of the surface porosity from 25 to 12 %, and adhesion strength from 23 to 19 MPa. In addition, the applied US field led to the change of the surface and structure morphology of the coatings. There was a local destruction of the structure elements (spheres and pores) and filling the pore spaces on the coating surface. The local macropores of 15-40 [mu]m in sizes were formed in the boundary to substrate layer. Режим доступа: по договору с организацией-держателем ресурса |
