鉴于其高温稳定性、抗氧化性、耐腐蚀性、耐磨性以及铁磁性能，镍（Ni）是技术上最重要的金属之一。本文报道了具有优异机械和磁性的纯纳米晶（Ni）薄膜可以在室温环境下增材打印而无需任何高温后处理。印刷工艺基于来自经典瓦特浴的基于电解质的电化学沉积。基于X射线衍射谱，印刷的Ni膜显示出优选的（220）和（111）织构。印刷的Ni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。磁电阻，磁滞回线，和磁畴成像显示了有前途的结果印刷镍功能应用。
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.
