Document Type and Number:
WIPO Patent Application WO/2016/009649
Kind Code:
A1
Abstract:
[Problem] To provide a treated surface aluminum material with excellent long term resin adhesiveness over the entire surface of the aluminum material and a stable manufacturing method for such a treated surface aluminum material. [Solution] Provided are a treated surface aluminum material and a manufacturing method therefor, wherein the treated surface aluminum material comprises an aluminum material and an oxide film formed on at least one surface thereof and is characterized in that the oxide film is obtained from a 20-500 nm thick porous aluminum oxide film layer formed on the front surface side and a 3-30 nm thick barrier aluminum oxide film layer formed on the base surface side, 5-30 nm diameter pores are formed in the porous aluminum oxide film layer, and the moisture content contained in the oxide film is not more than 10 µg/cm2.
