Which of the industrial ceramics has the best wear resistance?


The reason why industrial ceramics are very widely used in various fields, and its wear resistance is inseparable, then the next by the United States Cheng electronic ceramics manufacturer to introduce you to the industrial ceramics in which the best wear resistance performance.


Industrial wear-resistant ceramics as the name implies, with a certain wear resistance. Wear-resistant ceramics are ceramics with excellent wear resistance, the current application of more industrial ceramics are alumina ceramics, zirconia ceramics and silicon carbide ceramics. So which industrial ceramics have the most wear resistance?


From the current technical capabilities, alumina ceramics is the most wear-resistant, because he has good toughness, hardness is also high, the only drawback is the price is too high. Silicon nitride ceramics are also more wear-resistant, silicon nitride, the molecular formula for Si3N4, is an important structural ceramic materials. It is a super-hard material, inherently lubricious and resistant to wear and tear; strong corrosion resistance and oxidation resistance at high temperatures.


Alumina wear-resistant ceramics are special corundum ceramics made of AL2O3 as the main raw material and rare metal oxides as the melting agent, roasted at high temperature of 1,700 degrees. Then it is combined with special rubber and high strength organic/inorganic binder respectively.


Its wear resistance is 266 times that of manganese steel and 171.5 times that of high chromium cast iron. Its density is 3.6-3.9g/cm3, only half that of steel, which can greatly reduce the equipment load. Its performance characteristics include high hardness, good wear resistance, and light weight. Its Rockwell hardness is HRA80-90, which is second only to diamond and far exceeds the wear resistance of wear-resistant steel and stainless steel.
