Abstract Selective laser melting (SLM) is a promising additive manufacturing technology. In this paper, the printing system is composed of a control system and a printer. Modeled on the control system, the laser was used to print the powder layer by layer, and 316L stainless steel was successfully prepared. At room temperature and a constant frequency of 5HZ, the effects of different forming surfaces (XOY, XOZ, YOZ) and different loads (2 N, 5 N, 10 N) on the wear behavior of SLM 316L and rolled 316L were studied. The wear properties of SLM 316L and rolled 316L were compared. From the perspective of microstructure, the relationship between structure and wear performance was studied. The results show that due to the typical microstructure of SLM 316L, the wear performance of SLM 316L is better than that of rolled 316L. In addition, the load has little effect on the coefficient of friction, while the wear rate increases with the increase of load. When the load is small, abrasive wear mainly occurs. With the increase of load, adhesive wear and oxidation wear occur.

激光选区熔化316L的显微组织和磨损性能

摘要 选择性激光熔化（SLM）是一种很有前途的增材制造技术。在本文中，打印系统由控制系统和打印机组成。以控制系统为模型，利用激光逐层打印粉末，成功制备316L不锈钢。在室温和5HZ恒定频率下，研究了不同成形表面（XOY、XOZ、YOZ）和不同载荷（2 N、5 N、10 N）对SLM 316L和轧制316L磨损行为的影响。比较了 SLM 316L 和轧制 316L 的磨损性能。从微观结构的角度，研究了组织结构与磨损性能的关系。结果表明，由于 SLM 316L 的典型微观结构，SLM 316L 的磨损性能优于轧制 316L。此外，载荷对摩擦系数的影响很小，而磨损率随着载荷的增加而增加。当载荷较小时，主要发生磨粒磨损。随着载荷的增加，出现粘着磨损和氧化磨损。
