摘要： A method for treating a metal surface to reduce corrosion thereon and/or to increase the reflectance of the treated surface, the method comprising a) plating a metal surface with an electroless nickel plating solution; and thereafter b) immersion plating silver on the electroless nickel plated surface, whereby corrosion of the metal surface is substantially prevented and/or the reflectance of the silver plated surface is substantially improved. The treating method is useful for increasing the solderability of the metal surface, for example, in electronic packaging applications and in manufacturing light emitting diodes (LEDs).
