| 摘 要： | 通过对磷化膜微观形貌、元素组成以及对磷化液pH值及化学成分的分析，结果表明磷化过程中磷化液酸度过高，造成磷化晶粒过细，成膜不均匀，膜层厚度较薄，是导致钢管支架内壁磷化膜在较短时间内生锈失效的主要原因。通过调整控制镀液pH值1.5～2.0，新制备的磷化膜厚度及均匀性大大增加，其耐蚀性能得到有效提高。

| Abstract: | Through analysis of morphology, composition of phosphating film,pH value and composition of phosphating solution, the results showed that the excessive acidity inducing excessively fine crystals, discontinuous and thin film resulted in corrosion of phosphating film. After controlling 1.5-2.0 of pH in solution, characteristics of new phosphating fihn was effectively improved. |
