Document Type and Number:
WIPO Patent Application WO/2017/195805
Kind Code:
A1
Abstract:
The present invention relates to an aluminum alloy material that comprises: an aluminum alloy base material; and a coating film that is formed on at least one portion of the surface of the aluminum alloy base material and that comprises an oxide of aluminum that includes silicon. Over a pre-and-post-coating difference spectrum obtained by Fourier-transform infrared spectroscopy using parallel polarized light that is incident at an angle of 75°, the coating film has two absorption bands in the wavenumber range of 1000-1300 cm-1, and the two absorption bands are in the wavenumber ranges of 1080-1140 cm-1 and 1180-1240 cm-1. The Si content of the coating film is at least 20 at% but less than 70 at%, the Mg content of the coating film is at least 0.1 at% but less than 30 at%, and the Cu content of the coating film is restricted to less than 0.6 at%.
