采用室内加速腐蚀试验，通过表面形貌分析技术和电化学方法研究了盐雾环境中热镀锌、富锌涂料和重防腐蚀涂料对碳钢的保护作用。结果表明，在中性盐雾气氛和海水坏境中，重防腐蚀涂层保护效果最好，富锌涂层次之，热镀锌相对较差; 在酸性盐雾环境下，重防腐蚀涂层和富锌涂层皆有良好的保护效果，富锌涂层效果稍强于重防腐蚀涂层。

The protective effects of hot galvanizing, zinc-rich coating and high performance coating on carbon steel exposed to salt environments and simulated seawater were investigated using accelerated corrosion tests, surface morphology analysis and electrochemical methods. The results show that in the salt environment with a pH value of 6.5 or simulated seawater, the high performance coating showed the best effect in protecting carbon steel from corrosion. While in the salt environment with a pH value of 3.5, both the high performance coating and zinc-rich coating exhibited good protective effect and the zinc-rich coating was a little better.
