Abstract

PURPOSE: To form patterns at low cost without depending on mechanical means, by dipping Al or Al alloy in a solution of inorganic or organic compound containing S to treat by elecyrolysis, and then etching with alkaline solution.
CONSTITUTION: Al or Al alloy is pretreated in conventional process, and then dipped in a solution of inorganic compound such as sulfurous acid and persulfuric acid, or organic compound such as thioacetic acid, or metal salt of zinc sulfate, Ni sulfate, etc., possessing S which is easy to set free or decompose, then electrolytic treatment is applied by passing DC or AC superposed power supply. By selecting one or more than two kinds of said compounds, arbitrary patterns such as dot pattern and linear pattern may be formed. After electrolytic treatment, the material is etched in an alkaline aqueous solution, and strong recess etched pattern may be formed in the part of said pattern. Without requiring expensive facility in the conventional method, this method may be applied to materials of complicated shape at a low cost.
