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 ,从而提高了渗速
The effect of rare earth and oxygen on the effect of catastrophic gas infiltration was studied in the process of rare earth ionizing nitriding. The results show that rare earth is easy to combine with oxygen in the atmosphere of nitriding to remove part of the oxygen in the atmosphere and weaken the impediment of oxygen to nitriding,
