摘　　要：通过对65Mn,T8,40Gr和45等钢种的热处理工艺、金相组织及机械性能的研究,研制出了经济适用的残膜回收机弧形挑膜齿。结果表明,40Cr和65Mn钢的淬透性及硬度比45和T8钢高,并且65Mn钢的相对耐磨性最高。用45钢制作的弧形挑膜齿如果热处理工艺制定得科学合理,完全可以满足使用要求。By Researching the heat treatment technics and structure and character of 65Mn, T8,40Gr, 45 steel etc, the economy teeth arc on Plastic film residue collecting machine has studied. The results show that the 40Cr, 65Mn steel is higher than 45, T8 steel on quench hardening ,the wearable capability of 65Mn steel is the highest in all.If constituting science heat treatment technics to 45 steel,the teeth arc of Plastic film residue collecting machine are all right.
