Effect of Reciprocal Sliding on Severe-Mild Wear Transition

It is well known that adhesive wear is strongly dependent on load, sliding velocity, temperature and several other operating parameters. Besides these parameters, test configuration and type of motion also significantly affect the wear mode. For example, severe-mild wear transition is strongly dependent on the orientation of a test rig and the possibility of retention of wear particles on rubbing surface. It has earlier been shown that the retention of mild wear particles is crucial for severe-mild wear transition [1].
