Design of processes and tools for electrochemical machining of three-dimensional geometries in carbide-based materials

在电化学加工（ECM）中，导电材料的阳极溶解引起工件几何形状的特定变化，通常加工金属材料。在这项研究中，设计EC工艺或工艺链加工碳化物基材料的可能性应进行审查。因此，成形、成像和精加工过程将在理论上和实验上进行检验。此外，还应分析和评估加工碳化物基材料的适用性。为了克服非平凡表面氧化对阳极溶解的抑制作用，采用二次流体动力学和电过程作为工艺支持。该项目的目标是开发一种工具和工艺系统，用于使用电化学制造工艺在碳化物基材料中生产复杂结构。

In electrochemical machining (ECM) an anodic dissolution of electrical conductive material causes a specific change of the work piece geometry, where usually metallic materials are machined. In this study the possibility of designing EC process or process chains for machining carbide-based materials shall be examined. Thereby, processes of shaping, imaging and finishing are to be examined theoretically and experimentally. Furthermore, the applicability of machining carbide-based materials shall be analyzed and evaluated. To overcome nontrivial surface oxidation inhibiting the anodic dissolution, secondary fluid dynamic and electrical processes are used for the process support.The goal of this project is to develop a tool and process system for producing complex structures in carbide-based materials using electrochemical manufacturing processes.
