| 摘 要： | 采用硫酸铜点滴、线性极化、电化学阻抗等试验,对比研究了经硅烷偶联剂(SCA)和铬酸盐表面处理后的冷轧板的耐蚀性。结果表明经硅烷偶联剂表面处理后不但提高了基材的耐蚀性能,还提高了基材与涂层结合力,起到和铬酸盐钝化相同的防护效果。该方法有望取代造成环境污染的铬酸盐钝化工艺。

| Abstract: | The corrosion-resistance of the cold rolled steels treated with silane coupling agent(SCA) and chromate was studied by the tests of CuSO4 dropping,linear polarization and EIS etc.The results showed that the corrosion resistance of the steels and the adhesion between the steel and the coating were enhanced by the SCA surface treatment.The corrosion protection performance of silane treatment is comparable to that of chromate treatment,The conventional chromate could be replaced by the SCA treatment. |

| Keywords: | corrosion resistance silane coupling agent(SCA) chromate EIS linear polarization |
