The contribution of particle analysis to the study of wear of metals

Abstract The possibilities of particle tribology in general and ferrography in particular are discussed as means for identifying and quantifying the modes of wear as determined by environmental and operational factors. Whilst adhesion between interacting bodies occurs frequently, this cannot of itself cause wear particles to be formed and the importance of fatigue in the wear process is stressed with reference to Japanese work. The delamination theory of wear is summarized and adduced to explain the formation of thin plate-like particles which are usually encountered under low wear conditions. A series of experiments wherein discs in edgewise contact were subjected to various loads and speeds produced a predominant number of rubbing wear platelets together with occasional spheres and cutting-type particles. The application of the science of fracture mechanics to wear studies may illuminate the process of particle formation.
