| Abstract: | AZ31B magnesium alloy was used as the base material,and electroless plating of NiP-SiC was conducted under the alkalinity environment.The optimum formula and process conditions determined through orthogonal experiment were as follows:NH4F 60.0 g/L,Na3C6H5O7 · 2H2O 75.0 g/L,KI 0.06 g/L,SiC 6.0 g/L,NiSO4 · 6H2O 24.0 g/L,NaH2PO2 ·H2O 18.0 g/L,Cl8H29NaO3S 0.06 g/L,pH value 8.5,temperature 85 ℃,time 1 h.Under these conditions,the prepared Ni-P-SiC composite coating adhere well to the substrate and possess dense surface and compact structure,which resulting in better corrosion resistance and wear resistance. |
