Embodiment 1

[0032] A preparation method of a special lubricating and anti-friction coating for aluminum alloys of the present invention, comprising the following steps:

[0033] (1) Preparation of modified molybdenum disulfide / graphene nanoparticles

[0034] (1.1) Put molybdenum disulfide and silane coupling agent into an ethanol solution with a volume fraction of 95% at a mass ratio of 1:10, the silane coupling agent is aminopropyl triethoxysilane, molybdenum disulfide and silane coupling agent The mass ratio of the total mass of the agent to the ethanol solution is 1:20, and then acetic acid is added to adjust the pH value of the solution to about 4 to obtain a mixed solution. The mixed solution was stirred in an oil bath at 60°C for 6 hours, filtered, washed with ethanol for 3 times, and dried at 60°C for 24 hours to obtain a molybdenum disulfide pretreated product.

[0035] (1.2) Put molybdenum disulfide pretreatment product and graphene into N,N-dimethylformamide solvent at a mass r...
