This work investigates the role of the temperature of the bath on the structural properties, coercive force, surface morphology and surface texture of the electrochemically produced binary Ni–Co/ITO deposits in detail and presents the first results. It was found that the Ni/Co ratio of the deposit structure was not affected by increasing bath temperature. All resultant Ni–Co thin films comprising 19.5–20 wt% Co and 80–80.5 wt% Ni displayed a slightly anomalous co-deposition behavior. In all deposits, the crystallographic phase structure was the face-centered cubic with the [111] out-of-plane texture. Raising bath temperature gave rise to an improvement in the crystallization and an increment in the crystallite size. The roughness of the surface structure and the size of the surface particles first decreased with increasing bath temperature from 22 to 32 °C and then increased with further increase in the bath temperature. From the surface texture analysis, it was understood that increasing bath temperature did not affect the nature of the surface texture. When the bath temperature was 32 °C, the deposit exhibited the lowest coercive force. The results also indicated that the surface roughness and the particle size were predominant factors on the coercive force.

电化学生长的纳米结构 Ni-Co/ITO 薄膜的浴温相关结构特性、矫顽力、表面形态和表面纹理

这项工作详细研究了镀液温度对电化学生产的二元 Ni-Co/ITO 沉积物的结构特性、矫顽力、表面形态和表面纹理的作用，并展示了第一个结果。发现沉积结构的Ni/Co比率不受浴温度升高的影响。包含 19.5-20 wt% Co 和 80-80.5 wt% Ni 的所有所得 Ni-Co 薄膜都显示出轻微异常的共沉积行为。在所有沉积物中，结晶相结构是具有[111]面外结构的面心立方。提高浴温导致结晶的改善和微晶尺寸的增加。表面结构的粗糙度和表面颗粒的大小首先随着浴温从 22°C 增加到 32°C 而降低，然后随着浴温的进一步升高而增加。从表面纹理分析可以理解，增加浴温不会影响表面纹理的性质。当浴温为 32 °C 时，沉积物表现出最低的矫顽力。结果还表明，表面粗糙度和粒度是矫顽力的主要因素。
