Abstract
The study is devoted to a detailed analysis of the effect of the voltage level used in the microarc oxidation process on the tribocorrosive properties of calcium phosphate coatings formed on titanium substrates. The paper considers various voltage values (100 V, 200 V, 300 V), which were used to create coatings with unique morphological, structural and physicochemical characteristics. These features, in turn, have a significant impact on the mechanical properties of the coatings, their wear resistance and corrosion resistance. The research methodology includes profilometry for detailed analysis of surface texture, microhardness measurement for evaluation of mechanical properties, tribological tests for wear resistance, and potentiodynamic studies in saline solution to evaluate the level of corrosion resistance of coatings. The obtained results will provide an opportunity to better understand the mechanisms of influence of microarc oxidation parameters on the formation of calcium phosphate coatings and their performance characteristics. This, in turn, will be useful for the development of new materials with improved functional properties that can find wide application in the biomedical field, including the production of implants, as well as in industry where high corrosion resistance of coatings is required.
