“…Guided by the fact that many researchers consider the use of aluminate electrolytes the most rational for processing titanium [15,17,45], for comparison, a coating was also obtained in similar conditions. In this case, 15 g/L NaAlO 2 was introduced into the solution (aluminate electrolyte) instead of nickel sulphate at the processing time being 25 min.…”

The influence of Microarc Oxidation (MAO) modes of titanium substrate in electrolytes of the original composition is investigated. Used electrolytes no contain sodium silicate but includes nickel sulphate, sodium aluminate and alkali. The morphology and composition of the obtained coatings were studied by electron microscopy. The electrochemical behaviour was studied using polarisation curves and electrochemical impedance spectroscopy (EIS). Proposed Equivalent circuits are adequately corresponded to experimental EIS data with no more 6% error. The dependence between the elements of the Equivalent circuits and the morphological characteristics depending on the processing is considered. It is shown that MAO coatings on titanium have high corrosion resistance in an aggressive sulphuric acid. The electrochemical properties of coatings undergo irreversible changes in the direction of deterioration after anodic polarisation. It has been established that nickel doping of MAO coatings on titanium does not allow them to serve as anode materials.

In this investigation surface treatment of titanium alloy VT20 is carried out by phosphating and anodization in order to increase the adhesive bond strength. The surfaces were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), profilometry, contact angle measurements. The joined titanium specimens were shear tested before and after exposure to high humidity to a period of three months.

Microarc oxidation of alloys is widely used to obtain multifunctional coatings with unique properties. One of the topical issues in the application of the microarc oxidation is to increase the corrosion resistance of titanium alloys. In this article, the corrosion resistance of various microarc oxidation coatings of a titanium alloy in chemically aggressive liquids is determined. Comparative analysis of microarc oxidation coatings chemical resistance of the titanium alloy OT-4 showed a high coating resistance to the corrosive liquid exposure. The highest corrosion coefficient was determined when the alloy was exposed to concentrated sulphuric and hydrochloric acids. Virtually no corrosion of microarc oxidation coatings was observed in dilute acids (H2SO4 and HCl) and NaOH alkali solution.
