摘要
阐述了RB40合金的性能特点及正确的锻造方法,通过对该合金实施镀镍-稀土渗硼、等温淬火、高温回火复合处理,能得到很高硬度、耐磨性及抗高温氧化和冷-热疲劳抗力,应用于喷油泵滚轮体的热冲压冲头上,使用寿命比相应的热作模具钢可提高15～20倍。
The property of RB40 steel-bonded carbide and its correct forging method were described, and very high hardness,wearability,anti high temperature oxidate and cold-heat fatigue strength can be gained by plating,rare-earth boronizing,isothermal quenching,high temperature tempering.Appling the technique to spurt pump gyro wheel punch for hot-punching,the service life of the punch can increase 15～20 times than that of hot forming dies steel.
