Abstract
Surface characterization of PTFE composites in the case of water lubrication is discussed. Methods for analysis of surface quality are shortly presented. The study of the effect of wear is based on Abbott-Firestone curves which provide many advantages. Roughness studies were performed by the help of digital profilometer applied on PTFE samples. The surface quality study points out the statistical character of the information concerning the profile of composites with polymeric matrix. Keywords: PTFE, surface quality, Abbott-Firestone curves, water lubrication
