摘　　要：研究了一种用于钢铁表面的环保型钛盐化学转化膜处理工艺,给出了工艺流程、钝化液配方及工艺条件,并采用金相显微镜、EDS和盐雾试验等方法对膜的表面形貌、元素组成和耐腐蚀性进行了测试。结果表明,钢铁经此工艺钝化后防腐性能明显提高,其膜层主要由三氧化二钛组成。An environmentally friendly titanium salt chemical conversion coating treatment process on steel surface was investigated and the process flow, passivation solution and process condition were presented. The surface morphology, element compositions of the conversion coating and its corrosion resistance were tested by metallographic analysis, EDS and salt spray test. The results showed that the corrosion resistance of steel is improved remarkably after being passivated by the above process, and the main composition of coating is Ti2O3 .
