Prediction of Sliding Wear of Artificial Rough Surfaces

Abstract

When two surfaces are brought in contact, deformation takes place at asperity level. The local pressure distribution and deformation of the contacting surfaces are importance with respect to wear. This paper describes a wear model to predict the wear of rough sliding contacts. The wear model is based on the general Archard’s wear equation in combination with finite element analysis (FEA). In this paper the roughness is represented by uniformly distributed spherical asperities. The proposed model, FE in combination with Archard’s wear law, has proven to be a powerful tool in predicting wear of rough surfaces.
