Beschreibungen/Notizen

• One model that is offered for predicting the wear of minimally lubricated sliding parts suggests that wear may be predicted directly from the mechanics of contact. In this model the lubricant is assumed to carry part of the applied load and asperities carry the remainder of the load by solid contact and adhesion with each other. Experiments show that the assumed metallic adhesion does not take place on the predicted scale in ordinary practice, and thus catastrophic wear does not necessarily take place. The reason is that protective chemical species form on the asperities to prevent high surface shear stress. These films form in all practical systems but are particularly effective when a proper running-in procedure is followed.
