Examples
Embodiment 1
[0024] For workpieces based on aluminum alloy, 6061 is used here.
[0025] (a) Degreasing, descaling, activating and cleaning the workpiece of the above-mentioned aluminum alloy substrate;
[0026] (b) Put in the prepared nickel sulfate (A·R) 200~500 g / L, boric acid (A·R) 30~50 g / L, sodium chloride (A·R) 10~15 g / L, Saccharin (A·R) 1~2 g / L, sodium lauryl sulfate (A·R) 0.01~0.1 g / L, molybdenum disulfide (A·R) 5~20 g / L, the rest is water In the composite plating solution, the working temperature is 40~50℃, pH4.0~5.0, and the current density is 1~2A / dm 2 Under the best process conditions, the plating is carried out for 30 minutes. During the plating process, the plating solution needs to be continuously stirred by air to ensure the uniformity of molybdenum disulfide in the plating layer.
[0027] (c) After taking it out, wash it with water and dry it, and then directly carry out laser cladding treatment.
Embodiment 2
[0029] For workpieces based on copper, ZCuAl10Fe3 is used here.
[0030] (a) Degreasing, descaling, activating and cleaning the workpiece of the above-mentioned copper alloy substrate;
[0031] (b) Put in the prepared nickel sulfate (A·R) 200~500 g / L, boric acid (A·R) 30~50 g / L, sodium chloride (A·R) 10~15 g / L, Saccharin (A·R) 1~2 g / L, sodium lauryl sulfate (A·R) 0.01~0.1 g / L, molybdenum disulfide (A·R) 5~20 g / L, the rest is water In the composite plating solution, the working temperature is 40~50℃, pH4.0~5.0, and the current density is 1~2A / dm 2 Under the best process conditions, the plating is carried out for 30 minutes. During the plating process, the plating solution needs to be continuously stirred by air to ensure the uniformity of molybdenum disulfide in the plating layer.
[0032] (c) After taking it out, wash it with water and dry it, and then directly carry out laser cladding treatment.
Embodiment 3
[0034] For workpieces based on stainless steel, stainless steel 18-8 is used here.
[0035] (a) Degreasing, descaling, activating and cleaning the workpiece of the above stainless steel substrate;
[0036] (b) Put in the prepared nickel sulfate (A·R) 200~500 g / L, boric acid (A·R) 30~50 g / L, sodium chloride (A·R) 10~15 g / L, Saccharin (A·R) 1~2 g / L, sodium lauryl sulfate (A·R) 0.01~0.1 g / L, molybdenum disulfide (A·R) 5~20 g / L, the rest is water In the composite plating solution, the working temperature is 40~50℃, pH4.0~5.0, and the current density is 1~2A / dm 2 Under the best process conditions, the plating is carried out for 30 minutes. During the plating process, the plating solution needs to be continuously stirred by air to ensure the uniformity of molybdenum disulfide in the plating layer.
[0037] (c) After taking it out, wash it with water and dry it, and then directly carry out laser cladding treatment.
