| Abstract: | he effect of carburizing treatment on the oxidation resistance at high temperature of Ti-48Al-2Cr-2Nb(at.%)alloy was investigated.It has been found by test that the odidation resistance of TiAl basedalloy at elevated temperature can be effectively improved by this way.SEM, wave length spectrum analy-sis, EDAX and X-ray diffraction analysis were used to study the mechnism of enhance of oxidation resis-tance of TiAl based alloy by carburization. |
