Abstract

The aim of this work is to study the influence of MAO-coatings on the thermal state of the engine piston. The results of numerical modeling of the temperature distribution in the piston are presented for different values of thickness and conductivity of the coating. Regression equations are obtained. For thermal protection of the piston it is recommended to apply MAO-coatings with thermal conductivity of 0.3...0.7 W/m.K and thickness 150…300 µm.
