摘　　要：通过在自制渗硼剂中加入不同比例的稀土成分,进行对比试验,研究了稀土元素对45钢固体渗硼的催渗作用及其对其渗层的显微硬度的影响。研究表明:在渗剂中加入适量的稀土元素,对渗硼有一定的催渗作用,使渗硼层的显微硬度得到明显提高,但渗层的峰尖深度随稀土加入量的增加变化不明显。The rare-earth element infiltration catalytic action on the 45 steel in the solid- boronizing and effect on its infiltrating layer microhardness is analyzed through adding the different proportional rare-earth element in the selfmade boronizing agent and on trial by contrast. The resuh shows that adding proper rare-earth element in the boronizing agent can have a certain infiltration catalytic action on boronizing to improve the microhardness of the boronizing layer. However, the peak depth change of the infiltration layer is not obvious with increasing the amount of the rare-earth.
