Abstract Additive manufacturing of bulk metallic glasses (BMGs) through laser powder bed fusion (LPBF) has drawn growing interest in the last years, especially concerning industry-relevant alloys based on iron or zirconium. The process-inherent high cooling rates and localized melting pools allow to overcome geometrical restrictions given for the production of BMGs by classical casting routes. Yet, the achievable surface qualities are still limited, making an adequate post-processing necessary. In this work, we report on applying thermoplastic forming on LPBF-formed parts for the first time to decrease surface roughness and imprint finely structured surface patterns without the need for complex abrasive machining. This BMG-specific post-processing approach allows to functionalize surface areas on highly complex LPBF-formed specimens, which could be of interest especially for medical or jewelry applications.

增材制造的 Zr 基块状金属玻璃的热塑性成型:复杂结构表面处理的加工路线
摘要 近年来,通过激光粉末床融合 (LPBF) 增材制造块状金属玻璃 (BMG) 引起了越来越多的兴趣,尤其是与工业相关的基于铁或锆的合金。工艺固有的高冷却速率和局部熔池允许克服通过经典铸造路线生产 BMG 的几何限制。然而,可实现的表面质量仍然有限,因此需要进行充分的后处理。在这项工作中,我们报告了首次在 LPBF 成型零件上应用热塑性成型,以降低表面粗糙度并压印精细结构的表面图案,而无需复杂的磨料加工。这种 BMG 特定的后处理方法允许对高度复杂的 LPBF 形成的标本的表面区域进行功能化,
