| 中文摘要: |
| 目的 研究湿热海洋、干热沙漠大气环境对重要受力材料TM210A马氏体时效高强度钢腐蚀行为及机理的影响。方法 在万宁湿热海洋、敦煌干热沙漠2种典型大气环境中开展TM210A钢户外暴露试验，采用形貌观察、腐蚀产物膜分析、力学性能检测及断口观察等方法，分析暴露后TM210A钢的腐蚀行为及力学性能变化。结果 TM210A马氏体时效钢在湿热海洋、干热沙漠大气环境暴露2 a的抗拉强度分别下降6.0%、4.2%，断后伸长率分别下降16.7%、8.3%。在暴露1、2 a后，TM210A钢在干热沙漠环境中的力学性能下降量均低于其在湿热海洋环境中的力学性能下降量。结论 TM210A钢表面腐蚀是其强度和塑性下降的主要原因，TM210A钢在湿热海洋、干热沙漠大气环境暴露2 a后，表面均发生了明显的腐蚀，但在湿热海洋大气环境下腐蚀更严重，主要是由于湿热海洋大气环境湿度及Cl–浓度更高，加速了TM210A钢表面电化学腐蚀，降低了腐蚀产物层对基体的保护性。 |

| The work aims to investigate the effect of damp hot marine and dry heat desert atmospheric environments on the corrosion behavior and mechanism of TM210A maraging high-strength steel, which is an important load-bearing material. An outdoor exposure test was conducted on TM210A steel in two typical atmospheric environments, Wanning and Dunhuang. The corrosion behavior and mechanical property change were analyzed by means of morphology observation, corrosion product layer analysis, mechanical property test and fracture analysis. The results showed that the tensile strength of TM210A steel decreased by 6.0% and 4.2% and the elongation decreased by 16.7% and 8.3% after 2-year exposure to damp hot marine and dry heat desert atmospheric environments, respectively. The mechanical properties of TM210A steel in the dry heat desert atmospheric environmentdecreased by less than those in the damp hot marine environment. In conclusion, the surface corrosion of TM210A steel is the main reason for its strength and plasticity decline. TM210A steel has undergone significant corrosion on its surface after being exposed to damp hot marine and dry heat desert atmospheric environments for two years. However, the corrosion is more severe in the damp hot marineenvironment, mainly due to higher humidity and Cl concentrationin the environment, which accelerate the electrochemical corrosion on the surface of TM210A steeland reduce the protectiveness of corrosion product layer to the matrix. |
