稀土在离子渗氮中的除氧作用

Deoxidization Role Rare Earth in Plasma Nitriding Process

研究稀土催渗离子渗氮过程中 ,稀土与氧之间的作用对催渗效果的影响。结果表明 ,稀土易与渗氮气氛中的氧结合 ,使气氛中的部分氧被清除 ,削弱了氧对渗氮的阻碍作用 。

Effect of reaction of rare earth to oxygen on catalysis effect in plasma nitriding process catalyzed by rare earth has been studied in this paper. The results show that it is easy to combine rare earth with oxygen in nitriding at mosphere, lead to clear away the part of oxygen in the atmosphere, weaken the hindrance role of oxygen from nitriding, increase the nitriding velocity.
