This research evaluates the use of novel 3D-printed titanium alloy electrodes (3DPEs) as electrical discharge coating (EDC) on tungsten surfaces. Characterization through experimental analyses revealed that 3DPEs provide significant improvements in coating thickness and titanium content when compared to conventional EDC techniques. At suitable parameters, the 3DPE coatings achieved a thickness of 119.61 μm, surpassing conventional coatings at 15.18 μm. Additionally, the 3DPE coatings exhibited higher titanium concentrations, reaching 74.93%, indicating enhanced performance. A statistical analysis highlights the balance between surface roughness and material transfer rate (MTR), with conventional coatings exhibiting a more favorable balance. Optimal pulse on/off times maximize MTR and minimize surface roughness, respectively, with 3DPE coatings offering a more straightforward optimization path. Therefore, 3DPEs present a transformative approach to EDC, offering thicker, more uniform coatings with customizable electrical properties for diverse applications.

使用 Ti6Al4V 粉末 3DPE 方法在钨基体上增强放电涂层的表面性能


这项研究评估了新型 3D 打印钛合金电极 (3DPE) 作为钨表面放电涂层 (EDC) 的用途。通过实验分析表征表明，与传统 EDC 技术相比，3DPE 在涂层厚度和钛含量方面具有显着改进。在合适的参数下，3DPE涂层的厚度达到119.61μm，超过了传统涂层的15.18μm。此外，3DPE 涂层表现出更高的钛浓度，达到 74.93%，表明性能增强。统计分析强调了表面粗糙度和材料转移率 (MTR) 之间的平衡，传统涂层表现出更有利的平衡。最佳脉冲开/关时间可分别最大化 MTR 和最小化表面粗糙度，同时 3DPE 涂层提供更直接的优化路径。因此，3DPE 为 EDC 提供了一种变革性的方法，为不同的应用提供更厚、更均匀的涂层，并具有可定制的电气特性。
