摘　　要：为了研究300M钢在海洋大气环境下的接触腐蚀及防护问题。文章将不同接触方式的300M钢在青岛团岛大气暴晒1年后进行疲劳寿命的测定,通过扫描电子显微镜(SEM)观察疲劳断口形貌,并运用概率统计中的T检验处理疲劳数据,分析了海洋大气环境下300M钢的疲劳性能的影响。结果表明:海洋大气腐蚀环境下涂漆及涂胶装配都能可以有效预防300M钢腐蚀,从而有效提高300M钢的疲劳寿命。To solve the corrosion problem of 300M steel in marine atmosphere, the effects of different protection methods on corrosion fatigue behavior of 300M steel after one year exposure test in marine atmosphere have been investigated. Firstly, fatigue data were analyzed by T test of probabilistic method, and fatigue fracture morphology was observed by scanning electron microscope （SEM）. Finally, corrosion protection method was summarized for 300M steel. The results showed that the Marine atmosphere corrosion environment paint and glue assembly can be can be effective in preventing 300M steel corrosion. Surface painting is one of effective methods to prevent corrosion in marine atmospheric environment for 300M steel.
