Problems solved by technology

In the process of changing the needle tip, it is inevitable that the sample will be exposed to the air, and the uncertain factors brought about by the complex surrounding environment (including oxidation, electrochemical action, surface pollution, etc.) will make the test result deviate from the real one, which is not conducive to the experiment.

Abstract

The invention discloses a multi-probe friction wear test and in-situ morphology detection system in vacuum. The system includes a main body and an external manual driving device; the main body includes a cavity upper cover, a light window top cover mounted in the cavity upper cover and for sealing, and multiple probe components installed in the upper cover of the cavity. The system can realize switch of SPM probes with different functions, complete tribological test and in-situ morphology detection in high vacuum environment one after another, and reach high in-situ localization accuracy. The probe change does not need opening of the cavity, so as to ensure that the experimental sample is not interference by the external factors, and that the experiment results are more authentic. Besides, the system saves the previous calibration adjustment time for experiment equipment, and improves the efficiency.

Description

technical field [0001] The invention relates to a multi-probe tribology test and in-situ shape detection system under vacuum. Background technique [0002] Friction is a common physical phenomenon in the material world, and it is closely related to human life and production. Friction, wear and lubrication are the sciences and techniques that study the behavior of two surfaces in contact with each other and in relative motion. All equipment moving parts involve friction, wear and lubrication. The research on friction and wear phenomena has a long history and is still in the ascendant. With the development of science and technology, the study of tribology has penetrated into the microscopic world; and the friction and wear in the microscopic field is more conducive to revealing the origin of friction from the molecular and atomic levels. Most of these studies rely on the corresponding experimental equipment or instruments. [0003] With the development of science and techn...
