Abstract

A novel, environmentally friendly, fast, and flexible polishing process for Nitinol parts is presented in this study. Nitinol samples with both superelastic and shape memory properties at room temperature were investigated. The chemical contamination and surface roughness of superelastic Nitinol plates were examined before and after plasma electrolytic polishing. The shift in phase transformation temperature and tensile strength before and after the polishing process were analysed using Nitinol wire with shape memory properties. The obtained experimental results were compared to the data obtained on reference samples examined in the as-received condition. It was found that plasma electrolytic polishing, when the right process parameters are applied, is capable of delivering Nitinol parts with extremely high surface quality. Moreover, it was experimentally proven that plasma electrolytic polishing does not have a negative impact on functionality or mechanical properties of polished parts.

摘要

本研究提出了一种新颖、环保、快速且灵活的镍钛诺零件抛光工艺。对在室温下具有超弹性和形状记忆特性的镍钛诺样品进行了研究。在等离子体电解抛光前后，对超弹性镍钛诺板材的化学污染和表面粗糙度进行了检测。使用具有形状记忆特性的镍钛诺丝，分析了抛光过程前后相变温度和拉伸强度的变化。将获得的实验结果与在原始状态下检测的参考样品所得到的数据进行了比较。结果发现，当应用正确的工艺参数时，等离子体电解抛光能够生产出具有极高表面质量的镍钛诺零件。此外，实验证明等离子体电解抛光对抛光零件的功能或机械性能没有负面影响。
