PHYSICAL-STATISTICAL INTERPRETATION OF ABRASIVE WEAR OF SOLIDS,
Abstract
The author proposes a wear model for the abrasive wear of solids. The model scheme is based on the following: microscopic contacts appearing in the course of friction of deforming surfaces exist in coupled states of adhesion and slip which do not prevent the macroscopic movement continuity of one surface with respect to the other; contacts in a state of cohesion, similar to free particles, undergo small irregular shifts with respect to magnitude and direction under the effect of fluctuating forces from the side of adhering microscopic surface masses; certain 'anomalous' tangential shifts lead to the separation of adhering roughnesses from surfaces and to their ejection during subsequent moments of slip in the form of wear particles; and the strain of wear particle separation is proportional to the surface forming on the surface in this case.
