The authors, using sodium hypochlorite solution, hydrochloric acid, and sodium chloride, prepared acidic synthesized water having the same characteristics and composition as an anodically electrolyzed sodium chloride solution (acidic electrolyzed water). The following findings were obtained by investigating the characteristics of each solution and the dissolution behavior of copper. 1) The dissolved oxygen concentration and free chlorine concentration decrease immediately after electrolysis in acidic electrolyzed water. Their rates of decline are higher than in acidic synthesized water. 2) The dissolution rate and surface morphology of copper immersed in the respective solutions are almost identical. 3) Free chlorine in these solutions accelerates the dissolution rate. The dissolved chlorine increases the surface roughness of copper. 4) Oxygen nanobubbles probably exist much in acidic electrolyzed water. 5) Dissolution behavior of copper immersed in acidic electrolyzed water differs between during electrolysis and after electrolysis. Dissolution rate of copper is larger, and surface was not roughened in acidic electrolyzed water during electrolysis. These phenomena are presumably attributable to the actions of hydroxyl radicals generated during electrolysis.

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.

Electrolyzed alkaline water, obtained by the electrolysis of a dilute NaCl solution in a cathode compartment shows high pH (alkalinity), low ORP (Oxidation Reduction Potential), and moderate reducibility and oil-emulsification. By utilizing the characteristics of the alkalinity and the oil-emulsification of the electrolyzed alkaline water, metals and lead frames stamped with oil were washed and cleaned, then the cleanness of metals and lead frames for electronic products was evaluated. The surface analysis and quantitative data on remaining residual oils and ionic contamination, AES (Auger Electron Spectroscopy) analysis on metals, and wire-bond pull strength on the lead frames which were washed and cleaned by the electrolyzed alkaline water, showed the same level of cleanness compared to that of the conventional cleaning method by chemicals.

This paper describes development of end milling of carbon steel by electrolyzed reduced water of dilute sodium chloride solution, instead of conventional cutting with cutting fluid which is not environmentally consciousness. First, experimental equipments were built with a machining center, cutting fluid supply system made from the bath pump, temperature sensor and temperature recorder etc., and end milling processing of carbon steel was performed using electrolyzed reduced water of dilute sodium chloride solution and conventional cutting fluid respectively. Next, measured surface roughness, evaluated surface deterioration layer, temperature change of work piece and wear state of end milling. As the results of all evaluations above-mentioned, there is no difference between the end milling process using electrolyzed reduced water and that of conventional using cutting fluid. It is supposed electrolyzed reduced water instead of cutting fluid is environmentally consciousness process.
