摘要
研究了渗碳处理对Ti-48Al-2Cr-2Nb(at.%)合金高温循环氧化性的影响。试验发现,表面渗碳处理能够显著地改善TiAl基合金抗高温氧化能力。使用SEM、波谱分析、能谱分析和X射线衍射分析,研究了渗碳处理提高TiAl基合金抗高温氧化性能的机理。
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.
