摘要

QCr0.5合金进行内氧化时

在氧源中加入稀土粉末（Ce）

即在稀土气氛中进行内氧化

内氧化后测量内氧化层的厚度

并对试样进行硬度、导电性测试和组织观察与分析。结果表明

QCr0.5合金在稀土粉末气氛中进行内氧化时

内氧化层比无稀土气氛时内氧化的厚度大

也就是提高了内氧化的速率;稀土气氛下QCr0.5合金内氧化层的硬度比无稀土气氛的硬度大;稀土气氛提高合金的导电性。

Abstract

During QCr0.5 alloy internal oxidation

rare earth oxide powder was added in the oxide source to form rare earth atmosphere.After internal oxidation

the oxidation layer thickness

hardness and conductivity of the samples prepared were measured.In addition

the microstructure of the samples prepared was observed and analyzed.The results show that the oxidation layer and hardness of QCr0.5 alloy in rare earth atmosphere are higher than those without rare earths.Meanwhile

the electrical conductivity of QCr0.5 alloy is improved in rare earth atmosphere also.
