研究了表面渗碳处理对Ｔｉ－４８Ａｌ－２Ｃｒ－２Ｎｂ（原子分数）合金高温抗氧化性的影响结果表明，渗碳处理显著地提高ＴｉＡｌ基合金高温抗氧化能力，归因于渗碳处理在试样表面层形成了具有良好的抗氧化性和高温热稳定性的多层结构的渗碳层
The effects of surface carburization on the high temperature oxidation resistance of Ti-48Al-2Cr-2Nb (atomic fraction) alloys were investigated. The results show that carburizing treatment can significantly improve the high temperature oxidation resistance of TiAl-based alloys. Like the surface layer has a good oxidation resistance and high temperature thermal stability of the multi-layer structure carburized layer
