通过共电沉积平均尺寸为 39 nm 的 Ni 和 Cr 纳米颗粒，制备了一种新型 Ni-9.6 wt.% Cr 纳米复合薄膜。 Cr 纳米颗粒分散在电沉积纳米晶 Ni 颗粒中（平均 31 nm）。 800℃的氧化表明，与电沉积纯镍薄膜和未涂覆的镍基体相比，沉积态镍铬纳米复合薄膜具有优异的抗氧化性。 X 射线衍射表征和横截面研究表明，电沉积纳米复合薄膜上形成了连续的 Cr2O3 鳞片。 (C) 2003 Elsevier B.V. 保留所有权利。
A novel Ni-9.6 wt.% Cr nanocomposite film was prepared by co-electrodeposition of Ni and Cr nanoparticles in an average size of 39 nm. The Cr natroparticles were dispersed in the electrodeposited nanocrystalline Ni grains (31 nm in average). The oxidation at 800 degreesC showed that the as-deposited Ni-Cr nanocomposite film has a superior oxidation resistance compared to the electrodeposited pure Ni film and the uncoated Ni matrix. X-ray diffraction characterization and cross-sectional investigation indicated that a continuous Cr2O3 scale formed on the electrodeposited nanocomposite film. (C) 2003 Elsevier B.V.
