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.

Abstract

The invention relates to a reciprocating motion friction experiment device. The device comprises a base and a force measuring part, wherein a linear reciprocating motion part is arranged on the base; a motion platform is arranged on the linear reciprocating motion part; an experiment disk is arranged on the platform; a support part is fixed on the base; a strip-type substrate connected with a rotating shaft is arranged on the support part and rotates around the rotating shaft; the axis of the rotating shaft is vertical to the motion direction of the motion platform; a transmission part is fixed on the upper part of the substrate; the lower part of the substrate is connected with a loading part in a sliding mode; the upper end of the loading part is elastically connected with the lower end of the transmission part through a spring to form elastic force loading; an experiment pin clamping piece is arranged at the lower end of the loading part; and the force measuring part includes a first force measuring sensor arranged between the spring and the loading part and a second force measuring sensor arranged between the base and the lower end of the substrate along the motion direction of the motion platform. A correlation between the motion and load of an experiment sample and frictional wear is measured through an experiment. The device has high compatibility and strong functions and is easy to operate and low in cost.

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...
