摘要
本文应用电化学方法及物相分析技术研究了Ni_3Al-0.2B金属间化合物在熔融NaCl-(Na,K)_2SO_4中的腐蚀.发现Ni_3Al-0.2B耐熔盐热腐蚀能力极差,硫化-氧化是腐蚀破坏的主要原因.Ni_3Al-0.2B中添加6at.-％Cr,0.5at.-％Zr加速了材料的腐蚀。
Hot corrosion of Ni_3Al-0.2B in molten NaCl-(Na, K)_2SO_4 was studied by electrochemical methods and analytical techniques. The hot corrosion resistance of Ni_3Al-0.2B is quite bad, and the sulphidation-oxidation is responsible for corrosion damage. The addition of 6 at.-% Cr+0.5 at.-% Zr to Ni_3Al-0.2B may accelerate the hot corrosion.
