US07749582B2 Surface-treated metallic material, method of surface treating therefor and resin coated metallic material, metal can and can lid 有权
表面处理金属材料，表面处理方法和树脂涂层金属材料，金属罐和罐盖

Surface-treated metallic material, method of surface treating therefor and resin coated metallic material, metal can and can lid
Abstract:
A surface-treated metal material is obtained by forming an inorganic surface-treating layer containing at least Zr, O and F as chief components but without containing phosphoric acid ions on the surfaces of a metal by the cathodic electrolysis or by forming an inorganic surface-treating layer containing at least Zr, O and F as chief components and having an atomic ratio of P and Zr of 0≦P/Zr
Abstract(Chinese):

表面处理的金属材料是通过阴极电解形成无机表面处理层，其中至少含有Zr，O和F作为主要成分，但在金属表面上不含有磷酸离子，或者通过形成无机表面处理层， 处理层至少含有Zr，O和F作为主要成分，并且P和Zr的原子比为0＆nlE;通过阴极电解在金属表面的最上表面的P / Zr <0.6，成本低，特征高 生产力，环保性，抗疤性，粘合性，可加工性和贴合性。 通过使用通过用有机树脂，特别是用聚酯树脂涂覆表面处理的金属材料而获得的金属材料，金属罐或罐盖即使在高度加工的部分也表现出优异的粘合性和耐腐蚀性 。 此外，即使在通过加热灭菌后，罐盖也显示出优异的开口性能。
