摘要
灰铸铁经成分不同的中温磷化液处理后 ,磷化膜层的结晶形态差别较大 .分析认为Zn -Ca系比较适合用于灰铸铁的磷化 ,所处理的工件色泽呈深灰到黑色 ,耐蚀性好 ,溶液稳定 。
After teatment in phosphate solutions with different compositions at moderate temperature,the surface morphologies of the gray phosphate films formed on a gray cast iron are quite different.It is considered that the phosphate solution of Zn-Ca system is suitable for the gray cast iron.The treated samples show appearence of deep-gray or black and are good of corrosion resistance.The solution shows good stability with less deposit.
