Cryogenic treatment Wikipedia
20191030&ensp·&enspA cryogenic treatment is the process of treating workpieces to cryogenic temperatures (i.e. below −190 °C (−310 °F)) in order to remove residual stresses and improve wear resistance on steels and even composites. In addition to seeking enhanced stress relief and stabilization, or wear resistance, cryogenic treatment is also sought forProcesses&ensp·&ensp

20191111&ensp·&enspWear is the damaging, gradual removal or deformation of material at solid surfaces. Causes of wear can be mechanical (e.g., erosion) or chemical (e.g., corrosion). The study of wear and related processes is referred to as tribology. Wear in machine elements, together with other processes such as fatigue and creep, causes functional surfaces toWear types and mechanisms&ensp·&ensp

In fact, carbonitrided bearings are used widely for the guide rolls of continuous casting machines. In addition, it is possible to improve wear resistance more by using special steel that includes Cr and
Effect of Heat Treatment on Microstructure and
20131224&ensp·&enspThe casting conditions, and the evolved microstructure after heat treatment greatly affect the wear performance of high chromium white cast iron. Quenching, seeding and microalloying can, to a limited extent, increase the wear resistance, but this is best achieved by heat treatment in the solid state.

However, the scientific meaning of wear resistance is vague, and there is no specific unit to describe wear resistance. Nevertheless, the inverse of mass loss or volume loss is sometimes used as the (relative) wear resistance.
