On the empirical law of adhesive wear
WebWhen investigating the wear phenomena often there is a need for studying the wear process on the basis of variable parameters (microstructure, surface roughness, and load). A new experimental method was developed thorough several set of tests, by which the effects of the mentioned parameters in the wear process can be examined. The method … WebArchard's Wear Law may also be assumed to apply to the dressing tool. Although the above relationships have been derived on the basis of adhesive wear, a similar analysis applies to abrasive wear. For example, taking the abrasive cone model illustrated in Fig. 5.15, the volume of material removed in abrasion is
