Babbitt metal cubes were prepared by means of selected laser melting (SLM) process using Sn—11% Sb—6% Cu alloy powders; their microstructures were studied using optical microscope (OM), SEM, EDS, XRD and DSC; and their mechanical properties were tested using Vickers hardness and tensile methods. The results show that fully dense Babbitt metal components can be prepared by using appropriate SLM process parameters and an interlayer staggered laser scanning strategy. Anisotropy characteristics appear in both the microstructure and mechanical properties of SLM-Babbitt cubic specimens. The average hardness was in the range of 32.5 HV0.05 to 35.3 HV0.05. Both tensile strength and elongation were somewhat higher in a direction parallel to the laser scanning speed (Y axis) than in a direction perpendicular to the laser scanning speed (X axis). The strengthening mechanism is suggested to include solid solution strengthening of oversaturated Sb in the Sn matrix, as well as dispersion strengthening of finely dispersed SnSb and Cu₆Sn₅ particles. The overgrown acicular Cu₆Sn₅ phases at low laser scanning speeds and void formation at higher laser scanning speeds seriously deteriorate the mechanical properties of the SLM-Babbitt specimens.

通过选择的激光熔化（SLM）工艺，使用Sn-11％Sb-6％Cu合金粉末制备巴氏合金。用光学显微镜（OM），SEM，EDS，XRD和DSC研究了它们的微观结构。并使用维氏硬度和拉伸方法测试了它们的机械性能。结果表明，可以通过使用适当的SLM工艺参数和层间交错激光扫描策略来制备完全致密的巴氏合金成分。SLM-Babbitt立方试样的微观结构和力学性能均表现出各向异性。平均硬度在32.5HV0.05至35.3HV0.05的范围内。在平行于激光扫描速度（Y轴）的方向上的拉伸强度和伸长率都比在垂直于激光扫描速度（X轴）的方向上的拉伸强度和伸长率都高。₆ Sn ₅颗粒。在低激光扫描速度下过长的针状Cu ₆ Sn ₅相和在高激光扫描速度下的空洞形成严重恶化了SLM-Babbitt标本的机械性能。
