OXIDIZATION TREATMENT BASE MATERIAL WITH CATALYTIC ACTIVITY AND PRODUCTION METHOD THEREOF

摘要

PURPOSE: An oxidization treatment base material is provided which forms oxides with anodize-type titanium oxide on a chemically treated plate by an Al and the surface of alloy base material of Al group so that it shows light catalytic activity, deodorization, shock-resistance and contamination-proof characteristics. CONSTITUTION: An oxidization treatment base material is produced as follows: (1) oxides is formed on the aluminum plate and the surface of aluminum alloy base material which contain 1-10 vol% of anodize-type titanium oxide and is 0.1-0.5 micrometer in thickness; (2) the aluminum with above oxides is chemically treated to produce an oxidization film; and (3) the aluminum material is treated with a titanium oxide on the surface of chemical film treatment by Al with light catalytic activity.
