| 摘 要： | 对ＴiNi合金化学抛光液的组成和抛光工艺进行了研究和优化发现，化学抛光的质量不仅与抛光液配和抛光工艺直接相关，还与ＴiNi合金的处理状态有关，冷轧态固溶及退火态易获得低的表面粗糙度，用电化学方法测试了化学抛光与机械抛光试样的阳极极化曲线，结果表明，化学抛光能提高ＴiNi合金的点蚀电位（Ｅb) ,降低再钝化电位（Ｅrp)从而显著提高其耐蚀性，使化学抛光的表面达到镜面状态。

| Abstract: | Cailiao Baohu 2001, 34(1), 30～31(Ch). The chemical polishing technique and its effects on corrosion resistance of TiNi alloy were investigated by constant current and constant potential methods. A mirror-like surface of TiNi alloy could be made by the technique mentioned in this paper. The quality of polished surface was related to the previous treatments of alloy. The chemical pol-ishing could improve corrosion resistance of TiNi alloy obviously by in-creasing spot corrosion potential (Eb) and reducing re-passivating poten-tial(Erp). |
