| 摘 要： | 通过显微组织分析、动电位极化曲线和均匀腐蚀全浸试验研究了00Cr13Ni7Co5Mo4W马氏体时效不锈钢固溶温度1050~1150℃对该钢组织和人工海水中的耐蚀性的影响。结果表明,固溶温度影响马氏体时效不锈钢的组织均匀性和晶粒尺寸,进而影响该钢的抗点腐蚀能力;00Cr13Ni7Co5Mo4W马氏体时效不锈钢适宜的固溶温度为1100℃,经1100℃ 1 h固溶处理后,其年腐蚀速率仅为1.09μm/a,击穿电位为300 mV。

| Abstract: | The effect of solid-solution-treated temperature 1050-1150℃ on structure and corrosion resistance in artificial seawater of maraging steel 00Cr13Ni7Co5Mo4W has been studied by analysis on microstructure, using potentiodynamic polarization curves and uniform corrosion immersion testing. Results show that the solid-solution-treated temperature influences uniformity of structure and grain size of the maraging stainless steel, and then influences the pitting corrosion resistance of steel ； the suitable solid-solution-treated temperature of the maraging stainless steel 00Cr13Ni7Co5Mo4W is 1100 °C , and the annual corrosion rate of the maraging stainless steel 00Cr13Ni7Co5Mo4W solid-solution-treated at 1100℃ for 1 h is only 1.09μm/a, and the breakdown voltage is 300 mV. |
