Influence of Dilute NaCl Electrolyzed Water on Character of Al-Mg Alloy Cutting Surface

Abstract

This paper describes the elucidation about influence of dilute NaCl electrolyzed water on character of Al-Mg alloy cutting surface. First, the immersing experiment was conducted for cutting sample of Al-Mg alloy A5056B on the electrolyzed reduced water and electrolyzed oxidized water of 0.10wt% NaCl. Next, checked whether discoloration had occurred on sample surface, and analyzed the element distribution and chemical bond state on cutting surface by ASE (Auger Electron Spectroscopy) and ESCA (Electron Spectroscopy for Chemical Analysis). As results of the study, following could be identified. (1) Dilute NaCl electrolyzed water can be applied to processes, such as machining and surface treatment of Al-Mg alloy. (2) The element distribution of the Al-Mg alloy on cutting surface is controllable by dilute NaCl electrolyzed water. (3) The chemical bond state of aluminum element on Al-Mg alloy cutting surface is controllable by dilute NaCl electrolyzed water.
