摘要
A plating film is provided with enough hardness before anodic oxidation, which is hard to be damaged during handling, and also the production method of the plating film. This problem can be solved by an aluminum plating film with aluminum concentration of 98 wt. % or lower, and with a Vickers hardness of 250 or higher. The hardness is increased by containing oxygen, carbon, sulfur, and a halogen element as impurities. The impurity concentration is controlled by adjusting the current density, the plating temperature, or the plating bath composition.
