On the empirical law of adhesive wear
Web15 de jun. de 2004 · ABSTRACT. Careful measurements have been made of the wear of rubbing steel surfaces as a function of load, distance of travel, and hardness under controlled conditions which eliminated the effect of all factors except adhesion. Webamong other things, formulated the law of adhesive wear. This law is very simple and states that the volume V of worn material is proportional to the normal force, F, the …
