APPLICATION OF TITANIUM MICRO-ARC OXIDATION TECHNOLOGY TO IMPROVE THE PERFORMANCE CHARACTERISTICS OF MECHANICAL ENGINEERING PARTS

Microarc oxidation is one of the promising methods for processing titanium and its alloys, used to improve the performance characteristics of parts used in mechanical engineering. This method allows creating durable oxide coatings on the titanium surface, which significantly improve the tribological, mechanical and corrosion properties of the material. In this study, titanium samples subjected to MAO in various electrolytes were studied. The results demonstrate a significant increase in wear resistance, microhardness and corrosion resistance of the coatings compared to untreated samples. For example, after processing by the MAO method, the microhardness indicators increased almost twofold, and wear resistance increased several times, which confirms the high efficiency of this technology for increasing the service life of parts operating in severe operating conditions. In addition, the coating obtained by the MAO method improves the anti-corrosion properties of the material, which makes it suitable for use in aggressive environments. The use of MAO in mechanical engineering not only increases the reliability of equipment, but also reduces the cost of its maintenance and repair. This method can also be adapted for wide application in various industries, such as aviation and automotive. In conclusion, it can be noted that microarc oxidation is an effective technology for improving the performance characteristics of titanium parts, and its further development will contribute to the creation of new durable and wear-resistant materials for mechanical engineering.
