METHOD FOR PREVENTING ADHESIVENESS TO NICKEL PLATING FILM FROM DETERIORATING

摘要

PROBLEM TO BE SOLVED: To provide a method for preventing adhesiveness to a nickel plating film from deteriorating, without laminating an other film on the surface of the nickel plating film. SOLUTION: This method is characterized by keeping a plated article having a nickel plating film as the outermost layer, in such a state that the nickel plating film has, when the surface is analyzed by an X-ray photoelectron spectrometer with the use of a MgKαray as a X-ray source, 0.10 or more of a ratio (an area851.0-854.0 /an area851.0-859.4 ) of a peak area (the area851.0-854.0 ) in bonding energy of 851.0-854.0 eV, to the peak area (the area851.0-859.4 ) in bonding energy of 851.0-859.4 eV.
