摘要
将40钢试样在含稀土元素的LS_1渗硼剂中行进不同温度和时间的渗硼,然后用金相法测定层深,根据公式ρ~2=K_0te^(-Q/RT),对硼的激活能做了计算。经果表明,与未含稀土元素的LS_1渗硼剂相比,激活能降低了21％。
40 steel specimens are permeated in LS] addign boron with RE at different temperatures and times, and then the depths of seeping boron are determined by a metalloseope. The activation energy of seeping boron is calculated by making use of p2 = K0 te- Q/RT,and the result shows that there is a 21 % decrease in the activation energy as compared with LS] adding boron without RE.
