本文介绍了球化剂对固体渗硼的催渗作用。实验结果表明,在固体渗硼剂中加入适量的球化剂,可以显著提高渗硼速度。使渗层加深,过渡层加厚,硬度梯度变缓,脆性有所改善。分析认为,农业机械中有较多的承受摩擦磨损或磨粒磨损而受冲击较小的工件,更宜进行渗硼处理,若用球化剂复合催渗则可获得更好的技术经济效果。 In this paper, the effect of nodulizer on the infiltration of solid boron is introduced. The experimental results show that the addition of an appropriate amount of nodulizer to the solid borrower can significantly increase the boronizing rate. So that the deepening of the infiltration layer, the transition layer thicker, hardness gradient becomes slower, brittleness has been improved. Analysis, more agricultural machinery to withstand friction wear or abrasive wear by the impact of smaller workpieces, boron treatment is better to deal with, if the nodularizing agent complex seepage can get better technical and economic results.
