Abstract

The effect of the sandblasting pressure and the volume of alumina on the roughness of the substrate made of the AK12MMgN alloy, on the roughness of the deposited galvanic-plasma modification (GPM) coatings after blast cleaning, and on the adhesion strength of these coatings is investigate. It has been established that the proposed technology of surface treatment of cylinder-piston group (CPG) parts made of AK12MMgN alloy both before the application of GMG coatings and after their application to the above alloy makes it possible to obtain a heat-shielding layer, leading to significant fuel savings in diesel internal combustion engines. This method of treating the surfaces of the parts of a diesel engine CPG before and after applying heat-protective and wear-resistant coatings, confirmed by full-scale and bench tests, seems to be effective.
