    • In a method of manufacturing a metal member, a metal material containing aluminum as a main component is anodized in an anodization solution having a pH of 4 to 10 and containing a nonaqueous solvent having a dielectric constant smaller than that of water and capable of dissolving water, thereby forming a nonporous amorphous aluminum oxide passivation film on a surface of the metal member. The method includes a step of controlling the viscosity of the anodization solution. In the step of controlling the viscosity, the viscosity of the anodization solution is lowered by elevating the temperature of the anodization solution above the room temperature or by adding to the anodization solution a substance having a dielectric constant smaller than that of water and a viscosity lower than that of the nonaqueous solvent.
    • 在制造金属构件的方法中,以pH为4〜10的阳极氧化液阳极氧化含有铝作为主要成分的金属材料,并且含有比水的介电常数小的能够溶解水的非水溶剂 从而在金属构件的表面上形成无孔非晶态氧化铝钝化膜。 该方法包括控制阳极氧化溶液的粘度的步骤。 在控制粘度的步骤中,通过将阳极氧化溶液的温度升高到室温以上,阳极氧化溶液的粘度降低,或者通过向阳极氧化溶液中添加介电常数小于水的介电常数物质和较低的粘度的物质 比非水溶剂高。
