... 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...

... is the progressive loss of original material from a solid surface due to mechanical interaction between that surface and a fluid, a multicomponent fluid, an impinging liquid, or impinging solid particles ( Ref 1 ). Erosion is a rather broad term and can be further classified into a number of more specific terms...

... between two solid bodies (for example, sliding). The term erosion is used where the wear is caused by a fluid, a stream of particles, or bubbles (in the case of cavitation), not by contact between two solid bodies. The operational classification for nonabrasive wear situations ( Table 1 ) is directly...
