Ceramic grain size affecting the abrasion resistance
Ceramic grain size affecting the abrasion resistance
Abrasion resistant ceramic materials are widely used in the fields of grinding and polishing materials, wear-resistant coatings, pipes or equipment linings, equipment structural parts, etc. Their wear resistance directly determines the safe service life of mechanical equipment and parts. Common wear-resistant ceramic materials are diamond, zirconia, cubic boron nitride, silicon nitride, boron carbide, silicon carbide, various corundum and so on
Ceramic abrasion resistance property directly affect the application lifetime of wear resistance materials. And many scholars have studied the wear mechanism of ceramic materials and the factors affecting the wear resistance of ceramics , and think that ceramic grain size directly affect the abrasion resistance of alumina ceramics.
The scholars have studied the wear resistance of alumina and zirconia. It is found that the smaller grains are mainly plastic deformation and part of the trans granular fracture, and the wear is less; the larger grains are broken along the inside of the material. Even large dies are pulled out of the material to cause greater wear. The extraction of large-sized crystal grains will cause large defects on the ceramic surface, which will easily cause stress concentration and crack propagation, and cause low-stress brittle fracture of the material.
Pingxiang Chemshun Ceramics Manufacturer deeply recognize the importance of ceramic grain size, so high quality raw material should be chosen and tested before mass abrasion resistant ceramics production.at the same time. Strict quality control and advanced production and test equipment greatly improve the yield of ceramics
