    • A method includes applying a first powder to an aluminum article and heating the first powder to form a first layer on the aluminum article providing mechanical strength, corrosion durability and bonding potential. The method also includes applying a second powder to the aluminum article and heating the second powder to form a second layer on the aluminum article protecting the aluminum article from ultraviolet radiation. A coated article includes an aluminum substrate, an epoxy layer and a topcoat layer. The epoxy layer promotes adhesion, enhances corrosion durability and provides mechanical strength, and is formed by applying a first powder containing an epoxy to the aluminum substrate and curing the first powder. The topcoat layer provides resistance to ultraviolet radiation and environmental contaminants, and is formed by applying a second powder to the aluminum substrate and curing the second powder.
    • 一种方法包括将第一粉末施加到铝制品上并加热第一粉末以在铝制品上形成提供机械强度,腐蚀耐久性和结合电位的第一层。 该方法还包括将第二粉末施加到铝制品上并加热第二粉末以在铝制品上形成保护铝制品免受紫外线辐射的第二层。 涂覆制品包括铝基材,环氧树脂层和顶涂层。 环氧树脂层促进粘合,提高腐蚀耐久性并提供机械强度,并且通过向铝基材施加含有环氧树脂的第一粉末并固化第一粉末而形成。 面漆层提供对紫外线辐射和环境污染物的抵抗力,并且通过将第二粉末施加到铝基底并固化第二粉末而形成。
