.... Experimental studies in hot forming suggest that sometimes good lubrication enhances abrasive wear. This is because lower interface friction permits larger sliding velocities at the interface and, consequently, higher wear rates. In addition, lubrication inhibits the formation of brittle (untempered martensite...

... ). When steel parts are lubricated properly, the presence of oxide debris often is indicative of fretting. If a part is unlubricated or experiences a lack of lubrication, oxide debris may not necessarily signify fretting but rather other types of wear that can be prevented by proper lubrication. Fretting...
