中文摘要: 本文针对五种MCrAlY材料进行了700℃的热盐腐蚀试验,通过对材料表面、腐蚀产物、腐蚀截面、腐蚀失重等方面进行分析,研究Co、Cr、Al等MCrAlY的基本元素对700℃下含硫热腐蚀的影响。结果表明,700℃下,腐蚀产物以氧化铬、氧化铝为主,伴随少量尖晶石生成。腐蚀以网状氧化铝形貌向深处蔓延,网状氧化铝的附近往往伴随硫化铬的生成。Co、Cr为抗热盐腐蚀的有益元素,其中,Cr对抗700℃热盐腐蚀的提升作用优于Co元素。

Abstract:This paper conducted a hot salt corrosion test at 700°C on five MCrAlY materials. Through the analysis of the material surface, corrosion products, corrosion cross-section, corrosion weight loss and other properties, the effect of basic elements of MCrAlY such as Co, Cr, and Al on sulfur-containing materials at 700°C was studied. The results show that at 700°C, the corrosion products are mainly chromium oxide and aluminum oxide, accompanied by a small amount of spinel. Corrosion spreads to depth in the form of a reticular aluminum oxide, and the vicinity of the reticular aluminum oxide is often accompanied by the formation of chromium sulfide. Co and Cr are beneficial elements for resisting hot corrosion. Among them, resistance of Cr to hot corrosion at 700°C is higher than that of Co.
