ALUMINUM MATERIAL OR ALUMINUM ALLOY MATERIAL PROVIDED WITH COATING FILM, METHOD FOR PRODUCING THE SAME, AND AQUEOUS SURFACE TREATMENT AGENT

To provide an aluminum material or an aluminum alloy material with a surface treatment coating film that has excellent thermal and corrosion resistance.SOLUTION: The problem is solved by an aluminum material or an aluminum alloy material which has a coating film that contains chromium, zirconium, zinc and carbon in the surface or on the surface of the aluminum material or the aluminum alloy material, where the infrared spectrum of the coating film as determined by the specular reflection method of Fourier transform infrared spectroscopy (FT-IR) has peaks in the range of 3,600 cm-1 to 3,000 cm-1 and in the range of 1,750 cm-1 to 1,700 cm-1.SELECTED DRAWING: None 【課題】耐熱耐食性に優れた表面処理皮膜付きアルミニウム材又はアルミニウム合金材を提供する。【解決手段】アルミニウム材又はアルミニウム合金材の表面又は表面上に、クロム、ジルコニウム、亜鉛、及び炭素を含む皮膜を備えたアルミニウム材又はアルミニウム合金材であり、フーリエ変換赤外分光法（ＦＴ－ＩＲ）の正反射法にて測定された該皮膜の赤外スペクトルにおいて、ピークが３６００ｃｍ－１～３０００ｃｍ－１と１７５０ｃｍ－１～１７００ｃｍ－１とに現れる、アルミニウム材又はアルミニウム合金材により、課題を解決する。【選択図】なし
