Abstract
Finite element analysis of a coated SCMV (high-strength alloy steel) substrate with interlayer has been studied with the emphasized of stresses behaviour predicted in the substrate region due to the fretting wear surface profiles modification. The analysis is simulated using a simple cylinder-on-flat contact geometry under gross sliding condition for a given surface profile on a specific number of fretting cycles. The effect of interlayer stiffness on the stresses predicted in the substrate region is studied. It is found that the stresses in the substrate region are generally predicted to reduce with the increase of interlayer stiffness and with the advancement of wear.
