To describe the frictional interaction of a powder coating with a metal counterbody under steady wear, a statistical model has been developed based on the binomial distribution of removed wear particles. The profilometric method was used to study the microgeometry of contact surfaces in friction units «wear-resistant coating – steel counterbody» during sliding friction at room and low climatic temperatures. The analysis of profilometric data revealed that the distribution of heights of the friction surface profiles of wear-resistant coatings and counterbodies is mainly unimodal and is characterized by symmetry.
