Etching Effects of Electrolyzed Oxidizing Water on the Surface of Permalloy 45

Abstract

In this paper we discuss the etching effects of electrolyzed oxidizing water (EO water) on the surface of Permalloy 45. We threw light on the etching efficiency of NaCl EO water and Na2SO4 EO water on the surface of Permalloy 45 by comparing it with the etching efficiency of soaking in HCl solution and H2SO4 solution. The comparative study showed that as for the etching efficiency on Permalloy 45, NaCl EO water and Na2SO4 EO water was superior to HCl solution and H2SO4 solution. Also, EO water can process an etching equally to each composition elements of Permaooly 45 compared with chemicals.
