Recently, a strategy of synthesizing SiC whisker-reinforced nickel (Ni/SiCw) composites with excellent mechanical properties by electrodeposition has been proposed for exploring its potential applications in micromechanical devices. In this paper, a series of external conditions that affected the content of SiC whiskers in composite films were studied, such as cathode current density, stirring rate and electrolyte temperature. The experimental results indicated that the optimum morphology was obtained at a stirring speed of 300 rpm, a temperature of 50 °C, and a current density of 18 mA/cm2. Additionally, the content of SiC whiskers and textural preference were also investigated by varying its external conditions, and the results demonstrated that the composites with high mass percentage whiskers are more advantageous for electrocrystallization of Ni in the (200) orientation. Finally, the relationship between external conditions and intrinsic morphology, composition and texture of Ni/SiCw composites was revealed, and it provides a constructive approach to fabricate the high-content SiC whiskers of these composites.

Ni/SiCw复合涂层形态和织构的电沉积外部条件研究

最近，人们提出了一种通过电沉积合成具有优异机械性能的 SiC 晶须增强镍 (Ni/SiCw) 复合材料的策略，以探索其在微机械器件中的潜在应用。本文研究了影响复合薄膜中SiC晶须含量的一系列外部条件，如阴极电流密度、搅拌速率和电解液温度。实验结果表明，在搅拌速度为 300 rpm、温度为 50 ℃、电流密度为 18 mA/cm2 时获得了最佳形貌。此外，还通过改变其外部条件研究了 SiC 晶须的含量和质地偏好，结果表明，具有高质量百分比晶须的复合材料更有利于Ni在（200）取向上的电结晶。最后，揭示了外部条件与Ni/SiCw复合材料的固有形貌、成分和织构之间的关系，为制备这些复合材料的高含量SiC晶须提供了一种建设性的方法。
