摘　　要：为获得渗硼工艺参数对Cr12钢表面摩擦磨损性能的影响规律,采用浆料包渗法在Cr12钢表面制备渗硼层,对试样获得的渗硼层进行组织结构观察和摩擦磨损性能测试,研究供硼剂含量、渗硼温度及保温时间对渗硼层摩擦磨损性能的影响,并对试验结果进行分析讨论,结果表明:随着硼剂含量、渗硼时间和渗硼温度的增加,摩擦系数增大,耐磨性提高.To obtain effects of boronizing process parameters on the friction and wear properties of Cr12 steel,boronizing layer was prepared on the surface of Cr12 steel by using slurry pack cementation process.Friction and wear tests were then carried out to evaluate influences of boron content,boronizing temperature and holding time on abrasion resistance of the boronizing layer.The results show that friction coefficient increases and wear resistance is improved with increases in boriding content,boriding time and temperature.
