摘要

金属表面修饰

是一种有效的提高耐蚀性的手段。化学修饰同电化学修饰相比

操作简便

节能

而且实用性强

具有实际推广的意义。钛酸酯是由美国Kenrich石油化学公司开发的一类以Ti为中心元素的新型偶联剂。它有比较独特的分子结构

一端能与无机物表面的羟基反应

生成牢固的化学键

另一端能与有机物发生交联。由于钛酸酯的这一特点

其应用范围正在不断扩大

在涂料、粘合剂、塑料和橡胶等方面都得到了广泛应用。Sugerman和SalVatore研究了钛酸酯在水基和高固涂料中的耐蚀性能

探讨了烷基钛酸酯与金属表面清漆耐蚀性的关系。Yoshitaka等研究了α-Fe_2O_3经钛酸酯修饰后表面性质的变化

并初步探讨了钛酸酯与金属的成键方式。总之

钛酸酯的作用愈来愈受到重视。

Abstract

A modified composite of titanate and polymer (PVC) on the surface of carbon steel was investigated. The anti - corrosion performance of the modified specimen in various solutions was discussed by using some electrochemical techniques

such as polarization curve

polarization resistance and electrochemical impedance spectroscopy. The surface composition and structure of the modified film were analyzed by surface analysis techniques. The results showed that the modified composite film has good anti - corrosion performance in H2SO4 and NaCl solutions. The formation mechanism and protection mechanism of the modified film were discussed.
