[0002] At present, the known phenomenon of friction and wear of materials is ubiquitous. It is estimated that 1 / 3 of the world's industrial energy is lost by friction and wear, especially in extremely dry Friction and wear phenomena are more likely to occur in extremely humid environments. Therefore, the study of friction and wear is of great significance in many fields, and the development and research of friction and wear phenomena, theories, influencing factors, and friction-reducing and wear-resistant materials are inseparable from friction and wear. Testing machine. At present, although there are many types of friction and wear testing machines, there is a lack of friction and wear testing machines that can intelligently control the experimental humidity, especially the control of low humidity experimental environments. In addition, there are also methods to control the experimental humidity by adjusting the humidity of the laboratory environment. However, the experimental environment with too much humidity will affect the working stability of the friction and wear testing machine, and it takes a long time to reach the required humidity and the stability is poor.
