带有铋被膜的金属材料及其制造方法、在其中所使用的表面处理液以及阳离子电沉积涂覆金属材料及其制造方法
Abstract:
本发明提供涂覆追随性、耐腐蚀性和涂膜粘附性优异、可在低环境负担下制造的带有铋被膜的金属材料。该带有铋被膜的金属材料具有金属材料和在上述金属材料表面的至少一部分含有铋的层，上述带有铋被膜的金属材料表层中，铋原子的原子数比率为10%以上。
Abstract(English):

Provided is a metal material with a bismuth film attached, which has excellent coating properties, corrosion resistance and paint film adhesion, and which can be produced with little impact on the environment. The metal material with a bismuth film attached has a layer containing bismuth on at least part of the surface of the metal material, the numerical proportion of bismuth atoms at the surface layer of said metal material with a bismuth film attached being 10% or above.
