Аннотация

A model of contact fatigue damage of a coated body in high-cycle friction performed using a periodic system of indenters has been proposed. The influence of wear of non-fatigue origin on damage accumulation in the coating and substrate is studied. It is shown that the rate of damage accumulation in the coating decreases but remains unchanged or increases at the coating-substrate interface. Comparison of results for a constant and stochastically time-varying pressure distribution shows that variable loading increases the number of detachments of finite-thickness layers and inhibits contact fatigue damage accumulation at the interface.
