Sn-Ag-Cu alloy coating was prepared by using the self-developed Sn-Ag-Cu mesylate electropla-ting solution on brass substrate.The effects of electroplating process parameters on the composition,sur-face morphology,and thickness of Sn-Ag-Cu alloy coating were discussed by scanning electron microscope(SEM)and energy dispersive spectroscope(EDS).The results show that under the conditions of a current density of 4 A/dm2,a temperature of 25 ℃,and a pH of 5.5,the obtained Sn-Ag-Cu alloy coating has fine and dense crystals,smooth and bright surface,and uniform thickness.
