Abstract
The objective of this research is to investigate observable process changes during multi-layer friction surfacing of EN AW 6060 aluminum, whether for repair, remanufacturing, or new part manufacturing. In this study, friction surfacing was performed with a 10-mm-diameter rod of EN AW 6060 aluminum at spindle speeds ranging from 1000 to 7000 rpm to create up to three layers of 40-mm-long deposits on a substrate of the same alloy. The process forces and layer temperatures were observed. Post-process measurement of flash geometry, layer geometry and microhardness were conducted with the motivation to understand the impact of multi-layer depositions on performance and identifying acceptable conditions required to achieve acceptable build quality. The thickness, deposition and joining efficiency of layers in the multilayer configuration remained consistent. Friction surfacing of EN AW 6060 aluminum allowed for high deposition rates of 9 kg/hr, when compared to other metal additive technologies.
本研究的目的是研究ena6060铝合金在多层摩擦表面处理过程中可观察到的工艺变化，无论是用于修复、再制造还是新零件制造。在这项研究中，在主轴转速从1000到7000转/分的范围内，用直径10毫米的EN AW 6060铝棒进行摩擦表面处理，在同一合金的基底上形成多达三层40毫米长的沉积物。观察了工艺力和层温。为了了解多层沉积对性能的影响，并确定实现可接受的构建质量所需的可接受条件，对闪光几何形状、层几何形状和显微硬度进行了后处理测量。在多层结构中，层的厚度、沉积和连接效率保持一致。与其他金属添加剂技术相比，EN AW 6060铝的摩擦表面允许9 kg/hr的高沉积速率。
