The wear resistance of modern wear-resistant ceramics:
Hardness: The hardness of wear-resistant ceramic materials reflects the ability of ceramics to resist material pressure on the surface. The higher the hardness, the shallower the depth of material invasion and the smaller the volume of wear, resulting in higher wear resistance.
Strength: High strength can provide good support for resisting wear, fully exerting the ability of hard wear-resistant ceramics to resist wear. In other words, strength complements hardness.
Roughness: The smaller the roughness value, the higher the ability to resist fatigue wear. The roughness of ceramic surfaces is related to the fineness of the powder particles to some extent.
