Annotation

In work the characteristic of the basic directions of increase in a resource of pistons of engines is given, their basic advantages and lacks are considered. It is shown that the IA technology is the most progressive and competitive for increasing the heat resistance, wear resistance and durability of the ICE pistons. With the EA, energy costs are reduced by 80 times and the consumption of alloying materials by 90%. As a result of the tests it was found that the wear resistance of the strengthened piston increased by a factor of 2, and the wear of the "ring-groove" coupling in reinforced pistons decreased by 4 times. On the hardened surface of the pistons there are no cracks, chips and peelings, which indicates their high operational reliability; Reducing wear in the interface "ring-groove" an average of 35% allows you to increase the overhaul life of the engine, for example the D-240, - from 6000 to 8100 hours. On the basis of the obtained results of experimental studies, it is established that the piston AI affects not only the thermal stress of the cylinder-piston engine group, but also its specific power. As a result of calculations it was found that due to the use of IA, the specific engine power increased by 17-25%, and the piston resource increased by 1.97 times.

Keywords: engine pistons, service life, cylinder-piston group parts, aluminum alloys, ion nitriding, wear resistance, heat-protective coatings.
