Abstract

Spark plasma sintering (SPS) is a technique that uses resistive heating to enable rapid sintering. The ongoing industrialization of SPS is tied to the scaling of sintered parts. However, upscaling can lead to an inhomogeneous temperature distribution during sintering and to non-uniform properties in the sintered components. A solution lies in optimizing the SPS tooling design. The paper addresses this issue with a new digital twin, Leonardo 2.0, that numerically replicates the SPS setup. The digital twin is paired with an external database that contains properties of sintered and tooling materials. A control file governs the digital twin's operations in a specific case study. This editable ASCII file specifies the tooling geometry, materials, sintering cycle, boundary conditions, and output options. The paper demonstrates the application of the digital twin to analyze the impact of tooling components on the temperature distribution in electrically conductive (tungsten) and insulating (3YSZ zirconia) samples. The digital twin has great potential for applications in SPS tooling design across research and industry.

火花等离子烧结模具热管理的新型数字孪生体

火花等离子烧结（SPS）是一种利用电阻加热实现快速烧结的技术。SPS正在进行的工业化与烧结零件的结垢有关。然而，升级会导致烧结过程中的温度分布不均匀，烧结部件的性能不均匀。解决方案在于优化SPS工装设计。本文用一个新的数字双胞胎Leonardo 2.0解决了这个问题，它在数字上复制了SPS设置。数字孪生与包含烧结和模具材料特性的外部数据库配对。在特定的案例研究中，控制文件管理数字孪生的操作。这个可编辑的ASCII文件指定了模具的几何形状、材料、烧结周期、边界条件和输出选项。本文演示了数字孪生的应用，分析了工具部件对导电（钨）和绝缘（3YSZ氧化锆）样品中温度分布的影响。数字孪生在研究和工业领域的SPS工具设计中具有巨大的应用潜力。
