This study aims at exploring the wear performance of AISI 316L stainless steel fabricated via selective laser melting along different directions with respect to the building direction and via post annealing. Here, the wear resistance of the material was investigated via ball-on-disk tribology tests under a quasi-stationary condition, i.e., with linear sliding speeds in the range of 25–100 mm/s. The results revealed that, regardless the sliding direction and annealing heat treatment, the wear resistance of the alloy produced via the selective laser melting process is comparable to that of the cold-rolled alloy. Thus, the selective laser melting process can be used for applications where conventionally processed 316L alloys have been used under fretting or a quasi-static wear environment.

准平稳条件下选择性激光熔化的AISI 316L不锈钢的耐磨性的建立方向依赖性

这项研究旨在探讨AISI 316L不锈钢的磨损性能，该AISI 316L不锈钢是通过选择性激光熔化沿不同方向（相对于建筑方向）并通过后退火加工而成的。在这里，材料的耐磨性是通过在准平稳条件下（即线性滑动速度在25-100 mm / s范围内）的圆盘摩擦试验进行研究的。结果表明，无论滑动方向和退火热处理如何，通过选择性激光熔融工艺生产的合金的耐磨性均与冷轧合金相当。因此，选择性激光熔化工艺可用于在微动磨损或准静态磨损环境下使用常规加工的316L合金的应用。
