Notes:
The wear behaviours of alumina strengthen 3Y-TZP ceramics worn against high chromiumcast iron under various testing conditions were investigated using a block-on-block tribometer. Theresults showed that the wear rate increases with the increasing of the load and the sliding time. Under thelow load the main mechanism governing the wear properties of ceramic is the apparent plasticdeformation and ploughing, and the wear rate rapidly increases and the wear mechanism changes intobrittle fracture under high load. Meanwhile the wear resistance is depended on the properties of theabrasive particle. As expected, the wear resistance was increased with decreasing hardness of abrasiveparticle, but it was also influenced by the morphology, that is, the sharper the abrasive particle the higherwear rate
