在恒电位控制下,对固溶处理的以及敏化处理的In(?)660合金在高浓度NaCl溶液中的室温腐蚀疲劳性能进行了较系统的研究。结果表明,这种材料的腐蚀疲劳裂纹(?)由形变带的优先腐蚀溶解而产生的;敏化处理对Inconel600合金在室温4NNaCl溶液中的腐蚀疲劳性能具有有(?)影响;微量硫代硫酸钠或连四硫酸钠对Inconel600合金在室温高浓度NaCl溶液中的腐蚀疲劳过程具有抑(?)作用,这种作用可能是由于均匀腐蚀倾向增大及溶解速度增加,初始微裂纹被钝化或溶解(?)裂纹成核(?)难而产生的。
Under potentiostatic control, the room temperature corrosion fatigue properties of solution treated and sensitized In (?) 660 alloy in high concentration NaCl solution were studied systematically. The results show that the corrosion fatigue crack ()) of this material is caused by the preferential corrosion dissolution of the deformation zone; the sensitization treatment has a significant effect on the corrosion fatigue behavior of Inconel600 alloy in room temperature 4NNaCl solution; Sodium or sodium tetrasulfate has a suppressed (?) Effect on the corrosion fatigue process of Inconel 600 alloy at room temperature in high concentration NaCl solution. This effect may be due to the increase of uniform corrosion tendency and dissolution rate, the initial microcracking is passivated or Dissolved (?) Crack nucleation (?) Difficult to produce.
