SURFACE TREATED ALUMINUM MATERIAL, METHOD FOR PRODUCING SAME, AND RESIN-COATED SURFACE TREATED ALUMINUM MATERIAL

WIPO Patent Application WO/2013/118870

A1

[Problem] To provide: a surface treated aluminum material which has excellent bondability and adhesion over the entire surface of the aluminum material; and a method for producing the surface treated aluminum material. [Solution] A surface treated aluminum material which is provided with an oxide coating film on at least one surface. The surface treated aluminum material is characterized in that the oxide coating film is composed of a porous aluminum oxide coating layer that is formed on the surface side and has a thickness of 20-500 nm and a barrier aluminum oxide coating layer that is formed on the base side and has a thickness of 3-30 nm. The surface treated aluminum material is also characterized in that the porous aluminum oxide coating layer is provided with fine pores each having a diameter of 5-30 nm and that the fluctuation range of the total thickness of the porous aluminum oxide coating layer and the barrier aluminum oxide coating layer is within ±50% of the arithmetic mean of the total thickness in the whole surface of the aluminum material. Also provided is a method for producing the surface treated aluminum material.
