The processing method the copper membrane of doing the aluminum cooking instrument

摘要

This invention, anodizing the above-mentioned aluminum ware in regard to the processing method the copper membrane of doing aluminum ware, in order for 1st step and the metal copper stain membrane which form anodic oxidation layer on that surface to be formed, exposes the aluminum surface to the asymmetric variable voltage control interchange block electric current which possesses correct phase and negative phase and, the aluminum surface which with thing, is anodized includes with the 2nd step which is stained at electrolytic inside the tank the copper salt is included. This invention is obtained by the above-mentioned processing method, the copper membrane is accompanied, it regards also aluminum ware.
