摘要
本文根据铁丝在渗碳过程中截面平均碳浓度的变化规律,导出了电阻法测定碳传递系数β新的数学模型。该模型具有计算精度高,β、D可同时测定等优点。
Based on the variation of the section average carbon density in iron wire during carburizing process, a new mathematical model for the measurement of carbon transport cofficients has been proposed by electric-resistance method in this paper. With this model carbon transport cofficients can be calculated accurately. Besides both β and D can be measured simultaneously.
