在本文中，研究了层沉积过程中浴温对镍钴/碳化钨纳米复合涂层电化学/磨损响应的影响。 Ni-Co/碳化钨纳米复合涂层是通过在 20、40 和 60°C 三种 Ni-Co 浴温度下同时沉积碳化钨纳米颗粒而获得的。随后，为了表征所获得的涂层，在3.5wt% NaCl中进行了场发射扫描电子显微镜（FE-SEM）和透射电子显微镜（TEM）、X射线衍射（XRD）、MAP分析、动电位极化和电化学阻抗谱方法以及使用针盘法的磨损测试。这项研究的结果表明，从镍钴浴中获得的沉积物含有碳化钨纳米粒子，并在不同温度下在涂层中产生强（200）和硬（111）织构。另外，将镀液温度从20℃提高到40℃，会导致钴和碳化钨纳米粒子的吸收，同时降低镀层中的镍含量和耐腐蚀性，一方面提高镀层的耐磨性。然而，浴温从40℃升高到60℃会导致钴和碳化钨纳米粒子的吸收减少，镀层中镍含量和耐腐蚀性增加，同时镀层的耐磨性降低。
In this article, the effect of bath temperature during layer deposition on the electrochemical/abrasion responses of Ni-Co/tungsten carbide nanocomposite coating has been investigated. The Ni-Co/tungsten carbide nanocomposite coating was obtained using simultaneous deposition of tungsten carbide nanoparticles in three Ni-Co bath temperatures of 20, 40, and 60 °C. Afterwards, in order to characterize the obtained coatings, Field Emission Scanning Electron Microscopy (FE-SEM) and Transmission Electron Microscopy (TEM), X-Ray diffraction (XRD), MAP analysis, potentiodynamic polarization and electrochemical impedance spectroscopy methods in 3.5 wt% NaCl, and also abrasion test using a pin on disc method were carried out. The results of this study revealed that the deposition obtained from Ni-Co bath contains tungsten carbide nanoparticles and results in strong (200) and hard (111) textures in the coating at different temperatures. Also increasing the bath temperature from 20 to 40 °C results in the absorption of cobalt and tungsten carbide nanoparticles, as well as reducing the nickel content and corrosion resistance in the coating, and on one hand it increases the abrasion resistance of the coating. However, a bath-temperature increase from 40 to 60 °C results in reducing the absorption of cobalt and tungsten carbide nanoparticles, and increasing the nickel content and corrosion resistance in the coating as well as reducing the abrasion resistance of the coating.
