| 1 | 3D打印NiTi形状记忆合金在模拟不同口腔环境中电化学腐蚀行为研究显示文摘采用测量开路电位、极化曲线、电化学阻抗谱和Mott-Schottky方法研究了3D打印NiTi合金在不同人工唾液环境中的电化学腐蚀行为。结果表明,在纯人工唾液环境中,随着浸泡时间的延长,3D-NiTi合金的开路电位正移,合金的热力学稳定性提高,合金表现为典型的金属钝化极化特征,在人工唾液中可形成耐蚀稳定的钝化膜。添加可乐后,合金的热力学稳定性降低,极化曲线向左下方移动,自腐蚀电位负移,自腐蚀电流密度增大。添加1%NaF后,合金的热力学稳定性急剧降低,表现为活化腐蚀状态,钝化膜的缺陷数增加了3.7倍,F-可极大地破坏钝化膜的完整性。 | 刘明 王杰 朱春晖 张延晓 | 2023 | 中国腐蚀与防护学报2023，43，4： | 0 |
| 2 | Additive manufacturing of Cu-AI-Mn shape memory alloy with enhanced superelasticity显示文摘The Cu-based shape memory alloy(SMA)with highly oriented columnar crystals is an ideal candidate for the commercial application,especially the ones obtained through rapid cooling via additive manufacturing method.In this work,Cu_(71)Al_(18)Mn_(11)(at%)shape memory alloy with strong<001>texture columnar grains was successfully prepared by selective laser melting(SLM).An L27(313)orthogonal array was designed to systematically investigate the effects of laser power,scanning speed,scanning spacing,layer thickness and their interactions on the forming quality of Cu_(71)Al_(18)Mn_(11)alloys.Cu_(71)Al_(18)Mn_(11)alloys with density of 7.3204 g·cm^(-3)and relative density of 99.18%were successfully prepared when the laser power,scanning speed,scanning distance and layer thickness were 240 W,1000 mm·s^(-1),0.11 mm and 25μm,the transformation onset temperature(Ms),martensite phase transformation termination temperature(Mf),austenite phase transformation onset temperature(AS)and austenite phase transformation termination temperature(Af)are-21.84,-26.04,-15.75 and-12.36℃,respectively.The compression strength and fracture strain along the building direction(BD)were significantly superior to the scanning direction(SD),while the superelasticity of compression along the SD reached 2.50%,which was better than that of2.32%along BD.The mechanical property and superelasticity anisotropy due to the formation of columnar grains and texture were discussed.This study shows that SLM is a proposed method for the preparation of Cu-Al-Mn SMAs with high superelasticity,which provides a new strategy for enhancing the shape memory alloy superelasticity. | Meng-Wei Wu Zhuo-Fan Hu Bing-Bing Yang Ying Tao Rui-Ping Liu Chun-Mei Ma Lei Zhang | 2023 | Rare Metals2023，42，12： | 0 |
