... damage of the worn products after the tribological process. Then, the article describes some examples of wear processes, considering possible transitions and/or interactions of the mechanism of fretting wear, rolling-sliding wear, abrasive wear, and solid-particle erosion wear. The role of tribological...

... bearings are designed on the principle of rolling contact rather than sliding contact; frictional effects, although low, are not negligible, and lubrication is essential. The article lists the typical characteristics and causes of several types of failures. It describes failure by wear, failure by fretting...

Only a few attempts have been made to develop analytical models for predicting the wear process. The importance of determining analytical models for wear mechanisms has been discussed ( Ref...

... alternating stress field within the rolling-contact bodies, which eventually leads to material removal. The mechanism of RCF thus differs from the delamination theory of wear ( Ref 1 , 2 ), which also relies on cyclic loading but in sliding conditions and at asperity level. The alternating stress field...

The authors concluded that the energy dissipation in the linear sliding case occurred mainly by the rolling and shearing actions on the rolled...
