"Friction" is a quite common phenomenon, which is accompanied by human activities all the time, such as walking requires friction, driving of cars requires friction, and running of trains also requires friction. The physical phenomenon caused by this relative movement seems to be very friendly to human beings, but in fact, it often shows a ferocious side.
"Friction" is a quite common phenomenon, which is accompanied by human activities all the time, such as walking requires friction, driving of cars requires friction, and running of trains also requires friction. The physical phenomenon caused by this relative movement seems to be very friendly to human beings, but in fact, it often shows a ferocious side.
For example, in industry, the "friction" between two objects is often harmful, which will lead to the wear of object contact surfaces, and serious wear will even make the normal working motion mechanism invalid. In order to deal with this industrial enemy, people often use advanced ceramic materials with excellent wear resistance as a substitute for ordinary metals or plastics, or cover the surface of vulnerable workpiece with wear-resistant ceramics to improve its durability.
Compared with ordinary metals or plastics, wear-resistant ceramics have the following advantages: high hardness, high strength, good wear resistance, more than 100 times higher than manganese steel and high chromium steel, high temperature resistance, acid and alkali corrosion resistance, light weight, only half of steel, which can greatly reduce the load of equipment. Among them, alumina ceramics, with a very user-friendly price, is quite suitable for industrial applications, and has become one of the most commonly used wear-resistant materials in this field. It can be seen everywhere in ore crushing processing systems, raw material grinding systems, high-speed cutting and other "wild and unrestrained" occasions.
