Embodiment 1

[0027] The structural representation of the solid antibacterial lubricating film layer product of the space mechanism high binding force of the present invention, see figure 1 , where 1-substrate, 2-binding layer (Ti), 3-transition layer (TiN), 4-functional layer (MoS 2 -Cu-Ag), 5-functional layer (TiN).

[0028] The high-binding force solid antibacterial lubricating film layer product of the space mechanism includes: Ti / TiN / (TiN / MoS with a substrate of TC4 titanium alloy and a thickness of 2 μm 2 -Cu-Ag) nanocomposite multilayer film;

[0029] The specific preparation process is carried out in the following steps.

[0030] 1) Sputtering cleaning: the plated sample TC4 titanium alloy 6 is surface polished, ultrasonically cleaned with acetone, ultrasonically cleaned with ethanol and dried, then placed in figure 2 On the rotatable target platform 4 in the shown coating equipment, the vacuum chamber 7 is evacuated to 5.0×10 -3 Pa, through Ar, the control air pressure is 3.0×...

Embodiment 2

[0037] Under high load conditions, in order to improve the toughness of the coating and prevent the coating from peeling off due to brittle fracture, the preparation time of the TiN film layer in step 4 in Example 1 was shortened from 30min to 10min, and MoS 2 -The preparation time of Cu-Ag film layer is shortened from 30min to 10min, and the number of corresponding multilayer layers is increased from 12 to 36, and the outermost layer is MoS 2 -Cu-Ag film layer and keep the total thickness of film layer consistent, other steps are the same as embodiment 1.

Abstract

The invention relates to the technical field of material surface vacuum coating, particularly relates to a high-binding-force solid antibacterial lubricating film layer of a space mechanism and a preparation method of the solid antibacterial lubricating film layer. The solid antibacterial lubricating film layer comprises a basal body, a Ti bonding layer, a TiN transition layer, a TiN functional layer and MoS2-Cu-Ag functional layer, a nanocrystalline composite coating formed in sequence, wherein the TiN functional layer is connected with the MoS2-Cu-Ag The Cu-Ag functional layers are alternately arranged, and the outermost layer is an MoS2-Cu-Ag functional layer. The prepared nanocrystalline composite film is high in adhesive force, low in friction coefficient and good in antibacterial effect, the service life of the space mechanism system component can be greatly prolonged, and the reliability of the space mechanism system component can be improved.

Description

technical field [0001] The invention relates to the technical field of vacuum coating on the surface of materials, in particular to a solid antibacterial lubricating film layer with high binding force in a space mechanism and a preparation method thereof. Background technique [0002] The friction and wear of various moving parts in the space system, such as reaction wheels, gyroscopes, gears, pumps, transmissions, sealing devices, etc., is one of the main issues that determine the life of the space system. In addition, aerospace models also have a special type of material failure form-"corrosion" from the space environment. The good environment created by the manned space station for the long-term stay of astronauts also provides favorable conditions for the growth of microorganisms. Fungi and mold will corrode and degrade various materials of the space station, leading to the failure of space station equipment, the risk of platform failure and reduced airtightness. [00...
