Solid Lubrication Materials

Solid lubrication is an important component of lubrication. It overcomes some inherent drawbacks for liquid lubrication. Solid lubrication can be adopted in very harsh conditions such as high temperature, heavy load, ultralow temperature, ultrahigh vacuum, strong oxidation, and intense radiation, etc. In above conditions, liquid lubrication will lose its lubricating function. Solid lubrication materials are divided into four categories, i.e., soft metals, metal compounds, inorganic and organic materials. They have different lubricating mechanisms and can be applied to different situations.
