摘要/Abstract

摘要： 本文研究MAR-M247镍基超合金表面经铝化涂层或白金铝化涂层处理后,其热腐蚀效应对腐蚀速率与显微组织之影响,并藉试片质量增加量的变化评估抗热腐蚀的能力.铝化涂层之主要组成为-βN iA l相,而白金铝化涂层表面的主要组成为PtA l2相,利用盐喷覆法将Na2SO4被覆在试片表面,置于热处理炉中观测其热腐蚀性.实验得知,铝化涂层和白金铝化涂层均可明显抑制MAR-M247的热腐蚀,且后者之效果更明显,此两种涂层在910℃之Na2SO4环境中的抗蚀性均较MAR-M247合金为佳.

Abstract: This study is to investigate the high temperature hot corrosion behavior of aluminide coating and platinum-aluminide coating on Ni-base superalloy MAR-M247. On the platinum-aluminide, aluminide and the base metal, respectively, by the salt spraying method. The resistances to hot corrosion of platinum-aluminide coating, aluminide coating and the base metal were evaluated by the variations of weight gains. Aluminide and platinum-aluminide coating showed significanty beneficial effect on inhibiting the hot corrosion of MAR-M247. But that of the platinum-aluminide coating was even much better. The aluminide coating surface was composed of β-NiAl, and that of the platinum-aluminide coating was PtAl_(2). Both two phases could provide better resistances to hot corrosion than that of MAR-M247 in Na_(2)SO_(4), at 910℃.
