Hot corrosion behavior of NiCrAl-NiC sealing coating in thiochlorate

  • 摘要: 为探究NiCrAl-NiC封严涂层在高温熔盐环境下的腐蚀行为,使用大气等离子喷涂技术制备NiCrAl-NiC封严涂层。通过测量NiCrAl-NiC封严涂层的失重情况研究涂层的动力学变化,通过扫描电子显微镜(SEM)、X射线衍射(XRD)、激光共聚焦显微镜等方法,探讨NiCrAl-NiC封严涂层在650 ℃下混合硫氯酸盐(75% Na2SO4 + 25% NaCl)中的热腐蚀行为。结果表明:在进行10 h的热腐蚀实验后,NiCrAl-NiC封严涂层呈现出快速增重状态,增重速率为32.041 mg2·cm−4·h−1。在进行20 h的热腐蚀实验后,涂层由于表面氧化膜的脱落而发生减重现象。在热腐蚀进行了30 h后,涂层表面膜的生长覆盖了整个涂层,涂层表面形貌均匀,表面孔隙减少,可以对基体起到很好的保护作用。在完整的氧化膜的保护作用下,进行了40 h热腐蚀实验的NiCrAl-NiC封严涂层的质量变化速率为0.064 mg2·cm−4·h−1;通过XRD测试探究涂层热腐蚀后氧化膜的组成,发现热腐蚀后涂层表面的氧化膜以NiO和NiCr2O4为主。在热腐蚀过程中,尖晶石结构的NiCr2O4对涂层的热腐蚀起到了阻碍作用,是涂层腐蚀进程缓慢的主要原因。
