Abstract
The prospects of using nano-crystalline ceramic coatings on internal combustion engine parts obtained by micro-arc oxidation (MDO) technology are considered. The tendency of development of engine building on replacement of cast-iron blocks and sleeves on aluminum with the special coverings received by galvanic methods is shown. It is noted that this direction does not involve the use of repair technologies, which significantly affects consumers. Analysis and practical tests have shown the possibility of using MDO technology both in the manufacture of engine parts and for the performance of restoration work. It is concluded that it is necessary to introduce this technology into the mass production of engines and pistons, as well as the need to develop a set of equipment for repair work.
