EN In this paper, information about the durability of friction clutches under high heat conditions was described. As a way to extend their life and performance, thermal spray coating method is proposed. Process of modeling and conducting simulation in FEA (finite element analysis) environment was described. The thermal stress distribution in coating system in relation to the thickness of applied coating was investigated. Conducted simulation allowed to obtain data that presented strong correlation between coating thickness and both maximum value of Huber-Mises reduced stress and stress distribution characteristics within coating. Collected data allowed to evaluate the possibility of application of such coating on an aluminum plain clutch plate that works under high heat and dry conditions. Presented research has proven that design of such coating should especially cosnider coating thickness and thermal stress condiitons, as these factors may have strong influence on relibilty of cluth plates.
