To study dynamics of a coating wear, this paper deals with an uncoupled thermoelastic contact problem on sliding of a rigid punch over the surface of a thermoelastic coating bonded to an electroelastic interlayer, which itself is bonded to an undeformable substrate. Friction, frictional heating and coating wear on the contact is taken into account. The problem solution was constructed by the Laplace integral transform method and was obtained in the form of the Laplace convolutions. Based on the obtained expressions it is possible to develop technique for monitoring of a coating wear on a sliding contact through values of electric current arising in the piezoelectric interlayer.
