Abstract

The influence of the microarc oxidation parameters and electrolyte composition on the structure, properties and composition of CaP coatings modified with Zn– or Cu– incorporation on the Ti–40mas.%Nb (Ti–40Nb) alloy was investigated. The linear growth of thickness, roughness, and size of structural elements with process voltage increasing has been revealed. It was shown that the CaP coatings have the low contact angles with liquids and, consequently, high free surface energy. This indicates a high hydrophilicity of the coatings. X–ray diffraction analysis showed that the coatings have X–ray amorphous structure. The increase of the process voltage leads to the formation of such crystalline phases as CaHPO4 and β–Ca2P2O7 in the coatings. The maximum Ca/P atomic ratio was equal to 0.4, and Zn or Cu contents was equal to 0.3 or 0.2 at.%, respectively.
