摘要：
A chemical conversion coating formed on a surface of an aluminum substrate. The coating comprises a composite material formed by a reaction of a nitrate or sulfate of an alkali metal or alkaline earth metal and an organic compound that can form a compound with aluminum or exhibit a weak basicity an an aqueous aluminum treating liquid comprising the nitrate or sulfate of alkali metal or alkaline earth metal and the organic compound, with the aluminum substrate. The coating is corrosion-resistant, bacteria-proof or fungiproof, and the surface is of a heat exchanger, etc.
