Abstract

PURPOSE: To form antirust insulation films of superior durability, corrosion resistance and adhesiveness on copper surfaces by anodizing the surfaces in the solution which contains the specific concentration of aluminate ions and has been controlled to the specific pH by the oxide or hydroxide of one or more kinds of alkali metals or alkaline earth metals.
CONSTITUTION: Copper being the object to be treated having undergone pretreatments such as alkali degreasing and pickling is provided as anode in the alkali solution which contains aluminate ions at 0.1 g/l to saturation and has been controlled to pH 9 to 14 by using the oxide or hydroxide of one or more kinds of alkali metals or alkaline earth metals, whereby it is electrolyzed. The electrolysis forms and deposits the oxide film of copper containing the oxide of Al on the surfaces of the copper.
