Improvement of High-temperature Oxidation Resistance of TiAl-based Alloy by Cr-Si Plasma Surface Alloying AITranslate
Abstract AITranslate
Cr-Si was permeated into the surface of TiAl-based alloy by plasma surface alloying.Morphology,alloy element content and phase composition of the alloyed layer were characterized by SEM,EDS and XRD.Effects of surface alloying on high-temperature oxidation resistance of TiAl-based alloy were investigated.The results show that the alloyed layer is composed of Cr3Si and TiCr2 Laves phase.The main phases in the transition layer are Al8Cr5 and Al3Ti.Cr and Si concentration of the alloyed layer is of gradient distribution.The alloying surface layer is covered with dense CrO2 after high temperature oxidation,and the inner layer is a continuous Al2O3 barrier.The oxidation kinetics curve of the alloyed layer show a typical parabola.
