Use of graphite products----as wear-resistant and lubricating material

The use of graphite products is much higher than we expected, so what are the uses of graphite products we know so far?

Used as wear-resistant and lubricating material

In addition to the characteristics of high chemical stability, carbon and graphite materials also have good lubricating properties. Under the conditions of high speed, high temperature and high pressure, it is often impossible to use lubricating oil to improve the wear resistance of sliding parts. Graphite wear-resistant materials can work in corrosive media at temperatures from -200 to 2000 degrees Celsius and at high sliding speeds (up to 100 m/s) without lubricating oil. Therefore, many compressors and pumps conveying corrosive media widely use piston rings, sealing rings and bearings made of graphite materials. They operate without the addition of lubricants. This wear-resistant material is made of ordinary carbon or graphite impregnated with organic resin or liquid metal material. Graphite emulsions are also good lubricants for many metalworking (wire drawing, drawing tubes, etc.).
