                              磷酸液。磷化膜的品质优劣主要表现在晶体粗细和致密程?#21462;?#34920;面有无沉淀物及膜厚等方面,它们的差异直接影响磷化膜的品质。目前普遍采用磷化膜主要由铁系、锌系、锰系、锌钙系等磷酸盐溶液进行磷化,其中锌钙系性能最优良。控制工艺?#38382;?#20851;键要控制磷化温度(2540℃),时间(320min),促进剂含量(35气点)及总酸度(2040点)和游离酸度(0.83点)。

                               温度过太低则不能成膜或成膜速度慢,膜不完整,易泛黄?#29615;粗?#33180;粗大,耐蚀性低,同时槽液稳定性变差,沉渣增多。
