What is the wear resistance of ceramics? What are the main factors affecting the wear resistance of wear-resistant ceramics?
The wear resistance of ceramics refers to the ability of wear-resistant ceramic materials to resist mechanical wear. So what are the factors that affect wear resistance?
1. Hardness: The hardness of the wear-resistant ceramic material reflects the ability of the ceramic to resist the material being pressed into the surface. The higher the hardness, the shallower the depth of the material intrusion, the smaller the volume of wear, and the higher the wear resistance.
2. Strength: With high strength, it can provide good support for resisting wear and give full play to the ability of anti-wear and hard to resist wear, that is to say, strength and hardness complement each other.
3. Roughness: The smaller the roughness value, the higher the fatigue and wear resistance. The surface roughness of the ceramic has a certain relationship with the thickness of the powder particles under certain conditions.
Of course, in addition to the above three factors, the wear resistance of the material has a certain relationship with the toughness and defects of the ceramic. In daily production and procurement, we must grasp the main factors affecting wear resistance, improve strength and hardness, increase the smoothness of the surface of wear-resistant ceramics, and use composite steel plates and composite rubber to improve the toughness and resistance of wear-resistant ceramics. Impact capability, optimized wear-resistant ceramic properties.
