Description
陽極酸化皮膜層の膜厚を設計するのに用いられる表面処理アルミニウム材の素地の硬度がビッカース硬さの場合、陽極酸化皮膜層の膜厚は、素地のビッカース硬さが４０ＨＶ未満のとき陽極酸化皮膜層の膜厚が１５μm以上２５μm以下、好ましくは１５μm以上２０μm以下であり、表面処理アルミニウム材の素地のビッカース硬さが４０ＨＶ以上５０ＨＶ未満のとき陽極酸化皮膜層の膜厚が７μm以上２０μm以下、好ましくは７μm以上１２μm以下であり、また、表面処理アルミニウム材の素地のビッカース硬さが５０ＨＶ以上のとき陽極酸化皮膜層の膜厚が０．１μm以上１２μm以下、好ましくは２μm以上１０μm以下である。この素地のビッカース硬さと陽極酸化皮膜層の膜厚との関係が上記条件を外れると、塗膜硬度と塗膜密着性及び耐衝撃性とにおいて同時に優れた塗膜性能を有する塗膜層を形成することが難しくなる。 When the hardness of the surface-treated aluminum material used for designing the thickness of the anodic oxide film layer is Vickers hardness, the thickness of the anodic oxide film layer is anodized when the Vickers hardness of the substrate is less than 40 HV. When the thickness of the coating layer is 15 μm or more and 25 μm or less, preferably 15 μm or more and 20 μm or less, and when the Vickers hardness of the base material of the surface-treated aluminum material is 40 HV or more and less than 50 HV, the film thickness of the anodic oxide coating layer is 7 μm or more and 20 μm or less, The thickness is preferably 7 μm or more and 12 μm or less, and when the Vickers hardness of the surface-treated aluminum material is 50 HV or more, the thickness of the anodic oxide coating layer is 0.1 μm or more and 12 μm or less, preferably 2 μm or more and 10 μm or less. If the relationship between the Vickers hardness of the substrate and the thickness of the anodic oxide film layer deviates from the above conditions, a film layer having excellent film performance at the same time in film hardness, film adhesion and impact resistance is formed. It becomes difficult to do.
