Summary: | This paper describes the elucidation about the surface modification processing of permalloy 45 using Na sub(2)SO sub(4)-electrolyzed oxidizing water (It abbreviates as Na sub(2)SO sub(4) EO water). Firstly, as for the influence of Na sub(2)SO sub(4) EO water on the surface micro shape of permalloy 45 which was processed in the polish to the mirror surface, it was made clear using the results of FE-SEM observation and AFM measurement of the test pieces surface before and after immersion processing. The results is as follows. In the case of non-heating processing, if using Na sub(2)SO sub(4) EO water compared with the H sub(2)SO sub(4) solution and NaCl EO water, the test pieces surface is more uniformly done by the etching. In the case of heating processing, Na sub(2)SO sub(4) EO water, H sub(2)SO sub(4) solution and NaCl EO water are same and don't have big influence on the test pieces surface. Next, it reviewed about the removal of surface oxidation layer in the test pieces surface after heating processing. The results showed the surface oxidation layer can be more efficiently removed if using Na sub(2)SO sub(4) EO water compared with H sub(2)SO sub(4) solution; however, there is possibility that surface oxidation layer which is thicker than a natural-oxidation layer is formed. By this study, it got the possibility that Na sub(2)SO sub(4) EO water can be applied to the surface modification processing of permalloy 45. |
