Abstract
A thin coating made of linear elastic functionally graded material (FGM) perfectly bonded to an elastic substrate is considered. This work which is of particular interest to tribological community is devoted to the determination of the thermal and mechanical stresses due to mixed normal and tangential Hertzian surface pressure. The thermomechanical properties of the FGM coating are assumed to vary exponentially through the thickness. Solutions for temperature rise and stresses are obtained by use of Fourier transform technique. The influences of coating thickness, Peclet number and friction coefficient on temperature rise and stresses in the FGM coating are investigated. Comparative studies on FGM versus homogeneous surface coating under thermomechanical loading confirms that use of FGM coating could result in considerable reduction of surface temperature rise. The results also reveal that flexural tensile stresses in the FGM coating are significantly reduced.
