摘要
对八种商用冷作工具钢进行了热处理,使其硬度达到 650 HV。通过光学和扫描电子显微镜 (SEM)、显微硬度和 X 射线衍射 (XRD) 对热处理样品进行了研究,以确定微结构特征和相。分别在三种不同的磨损模式下对样品进行了检测:粘着磨损、在 SiC 上使用针磨损的双体磨损以及回收塑料切割机。通过三维扫描技术对样品的磨损表面进行了分析。钢的微观结构决定了其磨损特性。在低滑动和较高的切割速度下,由于切割线中产生的应力,钢的粘合磨损性能顺序发生了逆转。所有样品的磨损率都与载荷成正比。在循环塑性切削过程中,碳化物最少且分散均匀的试样磨损性能最好。对 S3 样品进行回火处理可防止裂纹形成并提高断裂韧性。
Wear characteristics of cold tool steels for recycling plastic preprocessing
Eight type of commercial cold work tool steels were heat treated to achieve the equal hardness of 650 HV. Heat-treated samples were investigated by optical and scanning electron microscopy (SEM), microhardness, and X-ray diffraction (XRD) to identify microstructural features and phases. The samples were examined in three distinct wear modes: adhesion, two-body wear using pin wear on SiC, and recycling plastic cutting machine, respectively. The wear surfaces of samples were analyzed by 3D scanning technology. The microstructure of steels determined their wear characteristics. For low sliding and higher cutting speeds, the order of adhesive wear performance of the steels was reversed due to the stress occurring in the cutting line. The wear rate of all samples was commensurate with load. In the recycling plastic cutting process, the sample with the minimum and homogeneously dispersed carbides exhibited the best wear performance. Tempering the S3 sample prevented crack formation and improved fracture toughness.
