What are the categories of materials used to manufacture friction pairs?
Thread Content
There are many materials available for manufacturing friction pairs nowadays. Commonly used non-metallic materials include carbon graphite, ceramics, polytetrafluoroethylene, and plastics; common metal materials include cemented carbide, nickel-chromium steel, chromium steel, bronze, carbon steel, and cast iron. In addition, surface treatment methods such as surfacing, sintering, and spraying, as well as composite processing techniques, are used to modify or improve the surface properties of friction pairs. All materials possess certain properties; when selecting materials for friction pairs, it is necessary to make use of their strengths while avoiding their weaknesses, and to choose them appropriately based on specific conditions.
The materials used to manufacture friction pairs are mainly divided into two categories: non-metals and metals. Non-metallic materials include carbon graphite, ceramics, polytetrafluoroethylene, and plastics, while metallic materials comprise cemented carbide, nickel-chromium steel, chromium steel, bronze, carbon steel, and cast iron. There are also methods to improve the surface properties of friction pairs through surface treatment techniques such as surfacing, sintering, and spraying, as well as composite processes. When selecting materials, their properties need to be considered in order to suit different usage conditions. .
