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.
