Galvanized steel has excellent corrosion resistance in atmospheric and soil corrosive environments, because a dense and passive zinc oxide film, formed on the surface could effectively inhibit the corrosion of the Fe substrate. The galvanized steel wire has been widely embedded in vegetation-growing concrete for reinforcement and showed good corrosion resistance and strengthening performance. However, in the marine area, the corrosion rate of galvanized steel is accelerated, and the galvanized steel wire will be failed in vegetation-growing concrete in a short time. This study has been carried out with a view to analyze the corrosion performance and corrosion mechanism of galvanized steel wire embedded in vegetation-growing concrete in the marine environment. EIS and Tafel curves were employed to study the corrosion performance of galvanized steel under different chloride concentrations and temperatures in vegetation-growing concrete lixivium. Results showed that the corrosion rate of galvanized steel increased with the increase of chloride concentration and the temperature in vegetation-growing concrete lixivium.

海洋环境中植物生长混凝土中镀锌钢的腐蚀与防护（一）：腐蚀性能

镀锌钢在大气和土壤腐蚀环境中具有优异的耐腐蚀性能，因为其表面形成致密的钝化氧化锌膜，可有效抑制铁基体的腐蚀。镀锌钢丝已广泛嵌入植被混凝土中进行加固，表现出良好的耐腐蚀性能和增强性能。然而，在海洋区域，镀锌钢的腐蚀速度加快，在短时间内镀锌钢丝将在植被混凝土中失效。开展这项研究的目的是分析在海洋环境中嵌入植被混凝土中的镀锌钢丝的腐蚀性能和腐蚀机制。采用 EIS 和 Tafel 曲线研究了镀锌钢在不同氯化物浓度和温度下在植被生长的混凝土浸出液中的腐蚀性能。结果表明，随着氯化物浓度的增加和植被生长的混凝土浸出液温度的升高，镀锌钢的腐蚀速率增加。
