Coatings Provide Protection from:
Stray abrasive particles, caught between mating surfaces
cannot gouge a hard ceramic coating.
Marginal lubrication is countered by the low
friction coefficient of ceramic coatings, also the minute surface pores
hold oil and therefore act as self-lubricating reservoirs.
Particle pull-out, caused by spot welding of mating
surfaces is prevented by the anti-galling properties of ceramic coatings.
Unlike metals, ceramics do not oxidize due to heat or
moisture, therefore there are no wear-causing oxides to wipe away in
Abrasive solids propelled by moving liquids or gases do
not erode hard tough ceramic coatings.
