本文研究了La对GBC-12合金在1030℃下抗高温氧化以及抗熔融玻璃腐蚀的影响。结果表明:La改善了氧化膜及腐蚀膜与基体金属的粘结性,促进了Cr的扩散,有利于CrO_3保护膜的形成,从而提高了该合金在1030℃时抗高温氧化和抗熔融玻璃腐蚀的能力。
In this paper, the effect of La on GBC-12 alloy at 1030 ℃ for high temperature oxidation and corrosion resistance of molten glass was studied. The results show that La improves the adhesion between the oxide film and the base metal and promotes the diffusion of Cr, which is favorable for the formation of the CrO_3 protective film and improves the high temperature oxidation resistance and the resistance to molten glass corrosion at 1030 ℃ Ability.
