Development of a Technological Process for the Production of Diesel Engines with Wear-Resistant Metallized Coating of Piston Heating Units.

The article shows that in most cases the reason for rejecting piston compression rings and cylinder liners is reaching the limit wear of the working rubbing surfaces and a conclusion is made about the advisability of applying a coating of a mixed steel-bronze pseudo-alloy to the working surface of the piston rings. The results of tribotechnical tests of a number of pseudo-alloys are presented, on the basis of which the optimal coating of piston rings is selected. The advisability of chemical-thermal treatment of metallization coatings is proven and the technological process of manufacturing piston compression rings with a wear-resistant coating is presented. In the water transport system, ship repair enterprises are faced with the tasks of improving quality, reducing the repair time of ship equipment, manufacturing replacement and spare parts in the required quantity, reducing the costs of raw materials, energy and materials.
