Abstract: To improve the corrosion resistance of Cu to GaIn alloy, Cr coating and Al coating were sputtered on the surface of pure copper by multi-arc ion plating.Cr/Cr2O3/Al2O3 composite coating, Cr/CrN/SiO2 composite coating and Al/Al2O3 /Al2O3 composite coating were prepared by in-situ reaction and sol-gel method. Corrosion tests were carried out in GaIn alloy at 60 ℃ and 200 ℃.GaIn alloy can cause severe pitting corrosion on the surface of copper block, but during the corrosion process, copper-gallium intermetallic compound which is attached to the surface of copper block will reduce the corrosion rate of GaIn alloy to copper block.GaIn alloy can cause serious corrosion to Al/Al2O3/Al2O3 coating.Large area of coating was desquamated. Cr/CrN/SiO2 coating was relatively stable in GaIn alloy, but the outermost layer of SiO2 showed a large amount of chipping. Cr/Cr2O3/Al2O3 coating was not obviously corroded in GaIn alloy. With the increase of corrosion temperature, the corrosion rate of GaIn alloy to samples also increased.The corrosion rate of copper at 200 ℃ was significantly more than 269 times that at 60 ℃, and the corrosion products adhering to the surface of copper were mainly CuGa2. Cr/Cr2O3/Al2O3 coating has the best corrosion resistance to GaIn alloy.Corrosion rate of Cr/Cr2O3/Al2O3 coating in GaIn alloy at 200 ℃ was 0.049 5 μm/h.The effect of Cr/Cr2O3/Al2O3 coating on thermal conductivity is around 1%.
