【摘要】：將帶Al2O3涂層和無涂層的GH3535合金在FLiNaK熔鹽中進行全浸腐蝕實驗,利用SEM,EDS,XRD等手段研究了有無Al2O3涂層的GH3535合金在熔鹽中的腐蝕行為.結(jié)果表明,有無涂層的GH3535合金在700℃的FLiNaK熔鹽中的腐蝕行為均表現(xiàn)出Cr,Mo的脫熔腐蝕特征,無涂層合金表現(xiàn)出顯著的沿晶腐蝕特征.Al2O3涂層并未提高合金的抗腐蝕性能,Al2O3涂層在FLiNaK熔鹽中發(fā)生了溶解,并與因Al2O3溶解脫落而裸露出來的合金表面形成腐蝕電池,從而加速了GH3535合金的腐蝕.
[Abstract]:The corrosion behavior of GH3535 alloy with or without Al _ 2O _ 3 coating in molten salt was studied by means of SEMMA-EDS- XRD and FLiNaK molten salt. The corrosion behavior of GH3535 alloy with or without Al _ 2O _ 3 coating was studied. The results show that the corrosion behavior of GH3535 alloy with or without coating in FLiNaK molten salt at 700 鈩，
