This paper describes the elucidation about the removal of Fe-42wt% Ni alloy (It abbreviates as alloy 42.) surface oxidation layer after heating processing using dilute electrolyzed oxidizing water. Almost, it clarified that electrolyzed oxidizing water could remove the surface oxidation layer of alloy 42, by the immersing experiment and the surface analysis of the samples. Next, it made clear when the barrier operation of the high nickel concentration area which was formed by heating processing, was cause about that the dissolved oxygen in electrolyzed oxidizing water didn't diffuse to the samples surface layer after the heating processing. Moreover, by the oxidation layer removal experiment which used the samples of the existence or non-existence of the heating processing, it reinspected that electrolyzed oxidizing water could remove alloy 42 surface oxidation layer after heating processing. Like oxygen, as for carbon there was not diffusion to the sample surface layer. The results indicate that electrolyzed oxidizing water can, indeed, be applied to remove alloy 42 surface oxidation layer after heating processing.
