摘要
A plating method for a nickel-titanium alloy member is provided which comprises the steps of: subjecting a nickel-titanium alloy member to an anodic electrolyzing treatment and a cathodic electrolyzing treatment in succession by using an electrolyte containing hydrochloric acid as an essential component thereof, in particular, an electrolyte having a chloride ion concentration of 0.1 mol/l or more and a pH value of 2 or less, or an electrolyte having a chloride ion concentration of 0. 4 mol/l or more, or still preferably, an electrolyte having a chlorine ion concentration of 0.3 mol/l or more and a pH value of 2 or less; strike plating the treated nickel-titanium alloy member with a desired metal; and electroplating the struck nickel-titanium alloy member with a desired metal. The adhesion between the nickel-titanium alloy member and a plating layer is very good.
