Abstract

The invention discloses an automatic evaluation device for the tribological property of a lubricating thin film. The device is composed of a friction testing machine, a friction force test unit, a vacuum system, a servo motor and an electric appliance control unit. According to the device, environments such as high-vacuum or atmosphere, nitrogen and helium environments and the like, and the friction testing machine with a servo motor system are optically integrated with an instrument with a preset start-stop logic relation and a relay switch control circuit; and a test device is capable of automatically evaluating the friction force, the friction coefficient, the friction life and the like of the lubricating thin film in the environments such as the high-vacuum or atmosphere, nitrogen andhelium environments and the like, and also can realize an evaluation test under manual control.

Description

technical field [0001] The invention relates to an automatic evaluation device for the tribological performance of a lubricating film, which belongs to the technical field of lubricating space machinery. Background technique [0002] The lubrication of space precision machinery is one of the necessary conditions to ensure high reliability, high stability and long life of space vehicles, but the preparation of lubricating film composite materials on precision parts is more complicated. For example, a physical vapor deposition method, a chemical vapor deposition method, an electrochemical deposition method, and the like. The lubricating film composite materials prepared by this kind of process need to carry out necessary tribological performance evaluation and screening of lubricating film material types in high vacuum, atmosphere and different gas environments, so that it is possible to further develop aerospace lubricant materials and engineering applications. Therefore, it...
