The basics of preparation technology of titanium triboengineering oxide coatings and their tests

The paper describes the developed basics of the preparation technology of solid ceramic coatings on titanium and its alloys. The coatings have been formed by the method of microplasma surface oxidation in electrolytes of different composition. The authors have determined the modes of wear-resistant coating application on titanium alloy, which have significantly decreased coating porosity and made it possible to increase its wear resistance. They have also carried out physical and mechanical, as well as tribological tests of the materials obtained and formed a database of their actual properties. The paper shows that self-lubricating coatings can be operated for a long time at moderate loads and sliding speeds in friction units without using a lubricant. It also describes a newly developed and improved existing equipment to create coatings and study their tribological properties.
