Abstract

PURPOSE:To easily remove an Ni-P alloy plating film from a plated Cu or Cu alloy member without damaging the Cu or Cu alloy substrate by immersing the member in a removing soln. having a specified compsn. and by carrying out anodic electrolysis at a specified electric potential. CONSTITUTION:When an Ni-P alloy plating film having superior corrosion, wear and heat resistances is removed from a plated Cu or Cu alloy member having a complex shape, the member is immersed in a removing soln. contg. 50-70wt.% sulfuric acid and 1-15g/l at least one kind of chloroacetic acid such as mono-, di- or trichloroacetic acid. The electric potential of the Cu or Cu alloy member having the Ni-P alloy plating film to the removing soln. is measured and anodic electrolysis is carried out while regulating the electric potential to above a value at which the Ni-P alloy is eluted and below a value at which the Cu or Cu alloy is dissolved or a value at which the Cu or Cu alloy is passivated and hardly causes dissolution. Thus, only the Ni-P alloy plating film is easily removed.
