In a previous study, the wear resistance of a large range ofceramic materials has been assessed on the basis of friction,abrasion, erosion (20 and 90°) as well as scratch tests. Except forthe last damaging mode, the wear behaviour has been compared withthat of non-ceramic materials (metal, polymer, rubber, etc) in orderto determine the wear modes following which ceramic materials giverise to some improvement. This comparative study initially performedby dry testing has been extended to aqueous media (neutral and acid).In presence of such media, it has been shown that most of thepreviously established wear-mechanical properties relationships canno longer be used to predict the wear behaviour.
