Embodiment 1
[0034] The nickel-based molybdenum disulfide powder for laser cladding includes the following components:
[0035] Molybdenum disulfide: 3%wt, particle size 200 microns;
[0036] Aluminum: 2%wt, particle size 0.1 micron;
[0037] The balance is nickel with a particle size of 50 microns.
[0038] Its preparation process includes the following steps:
[0039] (1) Add the molybdenum disulfide powder, aluminum powder, and nickel powder that have been confirmed in particle size to the ethanol solution, stir it into a paste, then add it to the mixed solution of 80% ethanol and 20% methanol, soak for 10-30min, Remove the dirt on the surface of molybdenum disulfide powder, aluminum powder and nickel powder;
[0040] (2) Select quantitative filter paper to filter separately, and place them in a drying oven at 120°C for drying treatment for 30-60 minutes to remove residual ethanol and methanol;
[0041] (3) Mix powder, weigh molybdenum disulfide powder and aluminum powder in proport...
