... compounds cause wear on rubbing surfaces in a form of parallel deep grooves. PTFE neither improves antiwear performance, nor reduces friction on the rubbing surfaces of steel. Friction modifier Boundary lubrication Wear mechanism High pressure Hon So' and Chih Chung Hu' Effects of Friction...

.... Special tests should be carried out in evaluating potential coolant candidates. It is not always true that coolant enhances tool life for milling. Wear mechanisms are presented by means of wear maps. Identified wear mechanisms are: micro-attrition, micro-abrasion, mechanical fatigue, thermal fatigue...

..., finer grain size and lower cobalt content. Observed active failure modes at high cutting speeds and feed rate were mainly chipping/fracture on the minor cutting edge for T1 and excessive nose wear for T2. The wear mechanisms on the former were interfacial sliding, dissolution/diffusion, and attrition...

... proportions of the two regions. Scanning electron microscopy (SEM) of the worn area shows clearly that different wear mechanisms dominate in the mild and severe wear regions. A possible wear transition model from mild to severe wear is discussed based on SEM observations of surface damage and the wear...
