Abstract

PURPOSE: To simply and quickly form very minute porous sand setting surface, by carrying out electrochemical sand setting by applying a specific alternating voltage in the electrolyte containing nitric acid, immediately after carrying out alkali etching of Al sheet.
CONSTITUTION: Electrochemical sand setting is carried out by alternating frequency wave current in the electrolytic solution containing nitric acid applying larger anode time voltage than cathode time voltage without dismatting by nitric acid, immediately after carrying out alkali etching of Al. Next, anodic oxidation treatment of Al is carried out continuously.
