摘要
从金相组织方面说明了采用同一固体渗硼工艺,40Cr钢的固体渗硼组织优于GCr15钢;同时从渗硼后的残余应力方面论述了渗硼后进行淬火加中温回火,可以减轻渗层脆性剥落,充分发挥渗硼层的耐磨性。附图4幅。
In the field of metallographical structure, the paper explains that if using same solid boriding technology, the solid boriding structure of 40Cr steel is superior tothat of GCr15 steel;meanwhile, in the field of residual stress after solid boriding, it expounds that carrying out quenching and medium tempering after solid boriding can reducebrittle f1aking of the boriding layer and bring wearing resistance of the boriding layer intofull play.
