Modeling of worn surface topography formed in a low wear process

Two types of worn surface topography modeling were used. For cylinder liners tests random one-directional Gaussian surface topography was imposed on the base surface (after honing). Worn surfaces of textured steel rings were modeled by simulation of actions of abrasive particles. After each kind of simulation selected parameters of measured and modeled surface textures were compared. We found that measured and simulated surfaces were correctly matched in the majority of cases.
