An enormous economic loss, as well as a waste of natural resources, is incurred world-wide as a result of wear of components and tools. Any effort expended in an attempt to reduce this loss is indeed worthwhile.
The purpose of this SAE Information Report is to present the current state of knowledge of abrasive wear. This report, therefore, covers wear, or the undesired removal of metal by mechanical action, caused by abrasive particles in contact with the surface. It does not concern metal-to-metal wear or wear in the presence of an abrasive free lubricant.
