Damage, erosion and fracture are the key reasons for the invalidity of machine parts, which are commonly found in metallurgical industry, engineering construction, power engineering, mechanical equipment and other industries, among which the damage problem is more serious. Especially for conveying equipment, about 80% of the invalid parts are due to the damage of raw materials. As a result, the problem of damage has been attached great importance by the raw material academia.

1. Harm of strength and relative density of grinding mediumThe relative density and strength of grinding medium play a key role in grinding efficiency: the higher the relative density of medium is, the higher the grinding efficiency is; The higher the strength is, the smaller the wear is, and the ea

As a kind of structural ceramics, zirconia has excellent properties such as high compressive strength, high strength, good wear resistance, corrosion resistance and heat resistance. In addition to being widely used in industrial production, along with the rapid development of denture field in recent
