Abstract

The invention discloses a nano multi-layer composite solid lubricating film layer with a long service life under space irradiation and preparation thereof. The nano multi-layer composite solid lubricating film layer composed of a Ti binding layer, a TiN bearing layer and an AgTiNi / MoS2Ti nano multi-layer lubricating functional layer is deposited on a titanium alloy substrate, an aluminum alloy substrate, a stainless steel substrate, a bearing steel substrate and the like by adopting a closed magnetic field unbalanced magnetron sputtering technology. The nano multi-layer composite film layer can reliably serve for a long time in strong space irradiation environments such as low-orbit high atomic oxygen density, medium-high-orbit high electron proton density and high ultraviolet irradiation dose, and is high in bearing capacity and low in friction coefficient, thus, the service life of a moving part of a spacecraft exposed in the space irradiation environments can be greatly prolonged, and the reliability of the moving part is improved. In addition, the preparation method has the characteristics that the process is environment-friendly and flexible, the film thickness is uniform, the compactness is good, the preparation process of the film layer is controlled in a programmed manner, the modulation period of the film layer is easy to regulate and control, and batch treatment can be realized, industrial production is easy to realize, and the good application prospect is achieved.

Description

technical field [0001] The invention relates to the fields of material surface vacuum coating technology and space environment engineering, in particular to a long-life nanometer multi-layer composite solid lubricating film under space irradiation environment and its preparation. Background technique [0002] Some materials in space vehicles (launch vehicles, etc.) and aircraft (artificial earth satellites, manned spacecraft, space stations, space probes, etc.) will produce friction and wear and cold welding effects during relative motion. Compared with ground applications, space The moving parts have their particularity in the service process. With the continuous development of my country's aerospace industry, the application of space moving parts is becoming more and more extensive and there are more and more types. Friction and wear are one of the main problems determining the life of space systems. Materials The tribological properties of the material are not entirely the ...
