Given its high temperature stability, oxidation-, corrosion- and wear-resistance, and ferromagnetic properties, Nickel (Ni) is one of the most technologically important metals. This article reports that pure and nanocrystalline (Ni) films with excellent mechanical and magnetic properties can be additively printed at room environment without any high-temperature post-processing. The printing process is based on a nozzle-based electrochemical deposition from the classical Watt's bath. The printed Ni film showed a preferred (220) and (111) texture based on x-ray diffraction spectra. The printed Ni film had close to bulk electrical conductivity; its indentation elastic modulus and hardness was measured to be 203 ± 6.7 GPa and 6.27 ± 0.34 GPa, respectively. Magnetoresistance, magnetic hysteresis loop, and magnetic domain imaging showed promising results of the printed Ni for functional applications.
由于其高温稳定性、抗氧化、耐腐蚀和耐磨以及铁磁性，镍（Ni）是最重要的技术金属之一。本文报道称，具有优异机械和磁性能的纯纳米晶（Ni）薄膜可以在室温环境下进行增材打印，无需任何高温后处理。打印过程基于从经典瓦特浴中进行基于喷嘴的电化学沉积。印刷的 Ni 薄膜在 X 射线衍射光谱中表现出优先的（220）和（111）织构。印刷的 Ni 薄膜具有接近体电导率；其压痕弹性模量和硬度分别测量为 203 ± 6.7 GPa 和 6.27 ± 0.34 GPa。磁阻、磁滞回线和磁畴成像显示了印刷 Ni 在功能应用方面的有前景的结果。
