Embodiment Construction

[0020] In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0021] Such as figure 1 As shown, a multi-environment vacuum friction and wear test system with sample transfer and X-ray photoelectron spectroscopy analysis functions, including a friction test chamber for friction test and environmental test, used to connect the friction test chamber and XPS analysis chamber , and a multi-interface sample transfer chamber to realize the transfer of samples between the two chambers, and an XPS analysis test chamber for surface element analysis of materials. The three chambers are connected by bellows and separated by plate valves. The first plate valve is used to separate the friction test chamber and the sample transfer chamber, and t...

Abstract

The invention provides a multi-environment vacuum friction wear test system. The vacuum degree of a sample conveying cavity is located between a friction test cavity and an XPS analysis test cavity, after a sample reaches the sample conveying cavity, the vacuum degree of the sample conveying cavity is extracted again until the difference value between the vacuum degree of the sample conveying cavity and the vacuum degree of the XPS analysis test cavity is smaller than a set value; therefore, the influence of the sample conveying cavity on the vacuum degree of the XPS analysis test cavity with the ultrahigh vacuum degree is greatly reduced, material samples can be transferred in cavities with different vacuum degrees, and it is ensured that the material samples are always in the environment isolated from the outside atmosphere in the whole process of friction tests, environment tests, sample conveying stages and XPS analysis.

Description

technical field [0001] The invention belongs to the technical field of vacuum equipment, in particular to a multi-environment vacuum friction and wear test system. Background technique [0002] Materials used in low-orbit environments need to experience a variety of space environments during the friction and wear process, including atomic oxygen and ultraviolet radiation, high and low temperature environments, etc., and the existing ground test equipment first conducts static atomic oxygen and Ultraviolet radiation test, and then conduct high and low temperature friction and wear tests on the materials after the irradiation test, which is completely different from the real friction and wear process of materials on orbit; after the friction and wear test is completed, in order to analyze the elemental composition and valence state of wear debris To judge the friction and wear behavior of materials, XPS elemental analysis is usually performed on wear debris. During the process...
