5.7.2 Types of wear

The types of wear can normally be divided in practice according to the stress. Sliding abrasion, grain sliding, rolling wear, impact and fretting wear are typical of closed tribological systems (see Table 11). Impact, cavitation, score grooving, scouring and jet wear occur in open tribological systems (see Table 12). The last two are also referred to as erosive wear.
It should be remembered that more than one wear mechanism can be active in any one wear process.
