摘要:
采用微型超临界反应釜进行了超临界水热液磷酸熔盐体系中，镍基合金Inconel 625在熔盐浸没下的腐蚀行为研究，通过扫描电镜（SEM）、能谱仪（EDS）和激光拉曼光谱（LRS），研究了超临界水热液磷酸熔盐对Inconel 625合金腐蚀行为的影响。结果表明，在含磷酸氢二钠的碱性超临界水体系中，磷酸熔盐会与NaOH熔盐形成混合熔盐引起Inconel 625合金的快速腐蚀增重。分析了超临界水热液磷酸熔盐中Inconel 625的腐蚀机理。
Abstract:
The corrosion behavior of nickel-based alloy Inconel 625 in supercritical hydrothermal phosphate molten salt system was studied by using a micro supercritical reactor. The effect of supercritical hydrothermal phosphate molten salt on the corrosion behavior of Inconel 625 alloy was studied by scanning electron microscope (SEM), energy dispersive spectroscopy (EDS) and laser Raman spectroscopy (LRs). The results show that in the alkaline supercritical water environment containing disodium hydrogen phosphate, the molten salt of phosphoric acid will form a mixed molten salt with the molten salt of NaOH, causing the rapid corrosion and weight gain of Inconel 625 alloy. The corrosion mechanism of Inconel 625 in supercritical hydrothermal molten salt was analyzed.
