Problems solved by technology

[0003] Surface texture preparation methods usually include reactive ion etching, LIGA technology, abrasive jet processing, laser texture processing technology, etc. DLC thin film preparation methods generally include physical vapor deposition and chemical vapor deposition, etc. These technologies are complex and costly. However, the surface texture and the DLC film itself have many influencing parameters. In order to study the tribological properties of the textured DLC film in a water-lubricated environment, a large number of friction and wear experiments are required.

Description

technical field [0001] The invention relates to the field of mechanical and material tribology research, and provides a reliable, efficient and low-cost testing and evaluation platform for evaluating the friction and wear performance of new materials. Specifically relates to a reciprocating motion friction experiment device which can provide a platform for general pin-on-disk type tribology experiments. Background technique [0002] In recent years, with the gradual enhancement of people's awareness of environmental protection and the increasing emphasis on safe production, the traditional oil lubrication method is facing a serious test. Due to the characteristics of non-pollution, wide sources, energy saving, safety, and flame retardancy, water has become one of the lubricating media with great development potential. However, the low viscosity of water, poor lubricity, poor electrical conductivity, high gasification pressure, and large difference from oil lubrication m...
