摘要
Laves相NbCr2的高温抗氧化性能限制了其作为高温结构材料在1200℃以上的应用进程.本文对Laves相NbCr2高温抗氧化性的研究进展进行了综合评述,着重介绍了Laves相NbCr2高温抗氧化性的影响因素及提高其抗氧化性的几种方法,包括合金化、稀土元素效应及防护涂层等,并就目前研究进展中的不足以及今后发展方向提出了一些看法.
The application of Laves phase NbCr2 at high temperaturs （over 1200℃） as high temperature structural materials in aeronautical and astronautical field is hindered by its poor high temperature oxidation resistance. Therefore,the research on the high temperature oxidation resistance of Laves NbCr2 compounds was reviewed. The factors having effect on their oxidation behovior were summarized and several methods for improving oxidation resistance of NbCr2 were mainly introduced, such as alloying, active element effect and protective coatings. Finally, the problems existed in the field and the development trend of the future research were pointed out.
