Abstract

The invention provides a method for solidly supporting molybdenum disulfide through a porous titanium oxide film, and belongs to the technical field of surface modification of metal materials. The method comprises the following steps: performing in-situ assembling on a porous titanium dioxide film on the metal surface of metallic titanium by an anodizing method; and then introducing a solid lubricant into the porous titanium dioxide film by a magnetron sputtering technology, wherein the minimum frictional coefficient of the titanium surface can reach 0.20 and is far less than the frictional coefficient of 0.46 of pure titanium; the solid lubricant can deposit on the surface of the porous titanium dioxide film and can be recycled in 4305 times; if the porous titanium dioxide film is not used, the lubricant falls off after being recycled in 15 times. According to the method, the technology of solidly supporting a solid lubricant in the porous titanium dioxide film is provided and can greatly decrease the frictional coefficients of the metallic titanium surface, and a novel effective measure is provided to solve the problem of meshing, caused by adhering, of a titanium alloy fastener.

Description

technical field [0001] The invention discloses a method for immobilizing molybdenum disulfide on a porous titanium oxide film, which belongs to the technical field of surface modification of metal materials. Background technique [0002] Titanium alloy has the characteristics of high strength, low density, good mechanical properties, good toughness and corrosion resistance, and is the material of choice for the aviation industry. However, titanium alloys have poor wear resistance and are prone to adhesion and seizure, which severely limits the application of titanium alloys in the aviation field. Molybdenum disulfide with a graphene-like structure has a low coefficient of friction and is an excellent lubricant. The solid lubricant MoS 2 Introducing it to the surface of metal titanium can reduce the friction coefficient of the titanium alloy surface, but the titanium alloy has high activity and is easy to form an oxide film on the surface, and the titanium and MoS 2 Direct...
