摘要：
本发明提供不含钴化合物、耐蚀性和耐伤性优异、处理液的稳定性高、顾及环境问题等的三价铬黑色化学转化膜处理液，含三价铬的水溶性修饰处理液以及使用这些处理液的金属基材的处理方法。三价铬黑色化学转化膜处理液，所述处理液是用于金属基材表面的化学转化膜处理液，含有如下组分且不含钴化合物：三价铬化合物；两种或多于两种的有机酸或有机酸盐、或者一种或多于一种的有机硫化合物；以及硝酸根离子。
摘要（英）：

Provided are a treatment liquid for a black trivalent chromium conversion coating, and a trivalent chromium-containing water-soluble liquid for finishing treatment, achieving excellent corrosion resistance and scratch resistance without containing a cobalt compound, with high stability and adequate consideration for environmental issues; and a method for treating a metal substrate using the same. The treatment liquid for a black trivalent chromium conversion coating on the surface of a metal substrate contains no cobalt compound, a trivalent chromium compound, two or more organic acids or organic acid salts, or one or more organic sulfur compounds, and nitrate ions, and contains no cobalt compound.
