A FRACTURE-INDUCED ADHESIVE WEAR CRITERION AND ITS APPLICATION TO THE SIMULATION OF WEAR PROCESS OF THE POINT CONTACTS UNDER MIXED LUBRICATION CONDITION

Adhesive wear is one of the four major mechanisms and very common in almost all macro-, micro- or nanotribosystems. In an adhesive process, tiny material fragments are pulled off from sliding surface adhered onto counterpart. Later these form loose particles transfer between contact surfaces. Because topographical physicochemical property non-uniformity engineering surfaces, happens heterogeneously on loaded it also discontinuous during rolling motion owing to damage accumulation fracture occurred inside subsurface layers. Taking account characteristics, a novel fracture-induced criterion has been proposed this study order predict local sliding. Moreover, applied predicting particle formation morphology evolution mixed lubricated rough surfaces reciprocating sliding, simulation results compared with ball-on-disk experimental measurements.
