General Patterns in Formation of Surface Layer of Machine Parts Treated by Combined Electro-technical Methods

The humanity has always needed new products and shorter time to incorporate them. These needs can be met by new technological processes based on a non-mechanical impact of an instrument on a blank, for example, on combined electro-technical methods. Combined electro-technological methods are the most popular in the technologies utilized in machine parts surface treatment based on sophisticated processes of metal dissolution. Rig testing allowed identifying certain physical and mechanical patterns in the increase of durability under the condition that strengthening and sizing combined electro-technical methods were used. In order to meet the requirements of the test, the suitable equipment, technological gear, and instruments were used, and the electrolyte environment class was ensured. The test confirmed the possibility of combining different methods of machine parts treatment that endures high tribological pressure. The best combinations and regime support were researched and identified. © 2020, Springer Nature Switzerland AG.
