摘　　要：采用膏剂法在890，920和950℃对工业纯铁进行稀土硼铝共渗及硼铝共渗，考察了稀土在各温度条件下对渗层生长动力学的影响。根据试验结果，通过计算机拟合给出了渗层生长动学曲线并建立了方程。结果表明，稀土在890和920℃作用较明显，曲线拟合度达99．0％以上，可用于渗层的预报和控制。The effect of rare earths on the kinetics of boron-aluminized layer growth of armco iron using Pasty method at 890, 920 and 950 t was studied. The kinetics curvers of layer growth andcorresponding equations were given with computer fitting. The results show that the effect ofrare earths is more obviously at 890 and 920 t. The curve can be used in forecasting and controlling of the larger.
