Embodiment 1
[0023] Cu-70%MoS 2 (or WS 2 , or Al 2 o 3 , or SiC) coated composite powder.
[0024] Pretreatment of MoS 2 Powder (or WS 2 Powder, or Al 2 o 3 powder, or SiC powder) 35g. MoS 2 The powder is evenly mixed with 210mL of alcohol, and after it is activated and dispersed, it will be used as the substrate for plating. Preprocessed MoS 2 Powder (or WS 2 Powder, or Al 2 o 3 powder, or SiC powder) was dispersed in 1000mL electroless copper plating solution, and then copper coating was carried out. The concentration or weight of each component in the electroless copper plating solution is: copper sulfate pentahydrate (CuSO 4 ·5H 2 O): 59 g / l; Reduced iron powder (Fe): 13.15 g. Heat the plating solution, stir evenly, and control the temperature to maintain at 90°C. After the coating experiment was completed, 0.05 g of benzotriazole was added to the solution of the copper plating layer and stirred evenly. Finally, the coating powder and the solution were separated and f...
Embodiment 2
[0026] Cu-39%MoS 2 -1% Al 2 o 3 Coated composite powder.
[0027] Pretreatment of MoS 2 Powder 9.75g and Al 2 o 3 Powder 0.25g. MoS 2 and Al 2 o 3 The mixed powder is evenly mixed with 60mL of alcohol, and after it is activated and dispersed, it is used as the substrate for plating. Preprocessed MoS 2 and Al 2 o 3 The mixed powder was dispersed in 1000mL plating solution, and then copper coating was carried out. The concentration or weight of each component in the plating solution is: copper sulfate pentahydrate (CuSO 4 ·5H 2 O): 59 g / l; Reduced iron powder (Fe): 13.15 g. Heat the plating solution, stir evenly, and control the temperature to maintain at 80°C. After the coating experiment was completed, 0.002 g of benzotriazole was added to the solution of the copper plating layer and stirred evenly. Finally, the coating powder and the solution were separated and filtered, washed with clean water, and dried in a vacuum oven at 90° C. for 1 hour. Preparation of...
Embodiment 3
[0029] Cu-15%WS 2 -15% SiC coated composite powder.
[0030] Preprocessing WS 2 Powder 3.75g and SiC powder 3.75g. Will WS 2 Mix the powder with SiC and 30mL of alcohol evenly, and after it is activated and dispersed, it will be used as the substrate for plating. Preprocessed MoS 2 and Al 2 o 3 The mixed powder was dispersed in 1200mL plating solution, and then copper coating was carried out. The weight of each component in the plating solution is: copper sulfate pentahydrate (CuSO 4 ·5H 2 O): 69g; reduced iron powder (Fe): 15.3g. Heat the plating solution, stir evenly, and control the temperature to maintain at 90°C. After the coating experiment is completed, 0.0125 g of benzotriazole is added to the solution of the copper plating layer and stirred evenly. Finally, the coating powder and the solution were separated and filtered, washed with clean water, and dried in a vacuum oven at 80° C. for 1.2 hours. Prepared Cu-15%WS 2 -15% SiC coated composite powder. Coat...
