This paper describes the elucidation about influence of dilute NaCl electrolyzed water on surface character of nickel material. First, the immersing experiment was conducted which is immerse industrial pure nickel material of 99.3mass%Ni and plating side of nickel into the electrolyzed reduced water and electrolyzed oxidized water of dilute NaCl. Next, weight, externals, and the surface shape of the samples to which immersing experiment was done were confirmed. Furthermore, the surface of the samples of 99.3mass%Ni industrial pure nickel material that after immersing was done was analyzed by Auger electron spectroscopy, and the change in the chemical composition and the change of the oxide film thickness etc. were clarified. As results of the study, following could be identified. (1) Dilute NaCl electrolysis water can be applied to the machining of the nickel material and the process of the surface treatment etc. before and after plating. (2) Electrolyzed reduced water doesn't give the influence to the surface of nickel material at all. Therefore, use as the cutting fluid is possible. (3) Electrolyzed oxidized water has the action that improves the etching action, the smoothing action, and the nickel purity for the surface of nickel material, and it doesn't discolor to the surface of nickel material. Therefore, electrolyzed oxidized water can be applied to oxide film removal processing line before plating.
