Study on the Elementary Process of Adhesive Wear: Generation of Wear Elements and Their Growth into Transfer Particles

摘要

The mechanism of adhesive wear is explained by a model for the formation of a wear particle through a mutual transfer and growth process. In the initial stages of this process, elemental debris of wear particles, which are called wear elements, are generated by contact between asperities. The wear elements with diameters of 10-30 nm have been observed by atomic force microscopy (AFM). In order to clarify the mechanism of wear and establish the wear equation, it is necessary to study the elementary process of wear. In this study, the influencing factors for the generation of wear elements and the formation of transfer particles in adhesive wear, have been investigated for the rubbing of pure metals.
