摘要

摘要: 镁合金具有质轻、比强度高、减震性好、生物相容性高等特点,在航空、航天、生物医疗等领域应用潜力巨大。然而传统的加工技术无法实现一体化复杂结构件的制备,严重制约了镁合金零件的应用推广。增材制造技术是一种基于"离散+堆积"原理的先进技术,有望成为解决镁合金复杂、薄壁结构件难加工的重要技术途径。本研究通过密炼机将高分子黏结剂与镁合金金属粉末混合,利用挤出机制备了适用于熔融沉积(FDM)技术的丝材原料,并研究了FDM工艺对生坯表面形貌的影响规律,采用正交实验和数据统计分析了工艺水平因素对尺寸精度的影响,并提出了后续烧结工序的改进方向。

Abstract: Magnesium alloys have the characteristics of lightweight, high specific strength, excellent shock absorption and high biocompatibility, which have great potential for the application in the fields such as aviation, aerospace, and biomedical engineering. However, the traditional processing techniques can hardly achieve the preparation of the integrated complex structural components, having seriously restricted the application and popularization of the magnesium alloy parts. Additive manufacturing technology is an advanced technology based on the principle of "discretization+stacking", which is expected to become an important technological approach to solve the problem of complex and difficult machining of thin-walled structural components of the magnesium alloys. In this study, an internal mixer is adopted to mix polymer binder with magnesium alloy powders, and an extrusion machine is employed to prepare wire materials suitable for the fused deposition modeling (FDM) process. The influence of FDM process on the surface morphologies of the green billets is investigated. The orthogonal experiments and data statistics are used to analyze the influence of process level factors on the dimensional accuracy, and the improvement directions for the subsequent sintering processes are proposed.
