Interest in electrocodeposition of nickel-based composite coatings has increased in recent years due to their unique combination of wear, magnetic, electrical, and corrosion properties (Ref 1). In general, composite coatings reinforced with hard oxide or carbide particles such as Al2O3, TiO2,SiO2, SiC, and WC or even diamond improves their wear resistance and reduces friction wear (Ref 2-4). Non-metallic inclusion such as WC and SiC in the metal changes its electron structure and crystal lattice that result in changes in the physical and mechanical properties of the electro-deposits(Ref 5, 6). On the other hand, metallic deposits such as carbon black (CB) and carbon nanotubes (CNT) incorporated in the metal through electrocodeposition result in formation of clusters. The electric fields are stronger around the CB/CNT clusters, than in other areas, which may result in increased local deposition rates and higher current densities. Under higher current densities, the differential depositing rates lead to a coarser surface. This may affect the mechanical properties of the composite coatings (Ref 7). |

| 近年来由于其独一无二的磨损，磁，电和防腐性能，镍基复合涂层的电沉积引起了人们广泛的关注。大体上，添加了比如Al2O3, TiO2,SiO2, SiC, WC或者钻石等坚硬的氧化物或者碳化物颗粒来提高他们的耐磨性，并减少摩擦磨损。非金属夹杂物，比如金属里面的WC，SiC改变了其电学结构和晶格，从而引起了在电沉积在物理，机械性能方面的转变。另一方面，比如金属中的炭黑和碳纳米管这类金属沉积能够通过电沉积形成簇。在CB/CNT簇的周围的电场比其他地方的电场强，使得在这些地方的沉积速度加快，并且有更高的电流密度，而不同的沉积速度就会产生粗造的表面，这就会影响复合涂层的机械性能。 |

| Interest in electrocodeposition of nickel-based composite coatings has increased in recent years due to their unique combination of wear, magnetic, electrical, and corrosion properties (Ref 1). 近年来，镍基复合镀层电化学复合共沉积技术由于其独特的耐磨性、磁性、电学和防锈蚀特性而日益引起关注。In general, composite coatings reinforced with hard oxide or carbide particles such as Al2O3, TiO2,SiO2, SiC, and WC or even diamond improves their wear resistance and reduces friction wear (Ref 2-4).通常而言，复合镀层的可由硬氧化物或碳化物微粒如Al2O3, TiO2,SiO2, SiC和 WC的加入而得到加强，甚或金刚石加入亦可改善镀层的耐磨性和减少磨损。 Non-metallic inclusion such as WC and SiC in the metal changes its electron structure and crystal lattice that result in changes in the physical and mechanical properties of the electro-deposits(Ref 5, 6). 金属中的非金属夹杂物如WC和SiC改变了金属材料的电子结构和晶格结构，导致电沉积物物理和力学特性的变化。On the other hand, metallic deposits such as carbon black (CB) and carbon nanotubes (CNT) incorporated in the metal through electrocodeposition result in formation of clusters.另一方面，金属沉积物，如通过电化学复合共沉积技术包含炭黑和碳纳米管在金属中者导致簇的形成。 The electric fields are stronger around the CB/CNT clusters, than in other areas, which may result in increased local deposition rates and higher current densities. 炭黑/碳纳米管簇周围的电场强度高于其他区域，可能导致局部沉积率增加和较高的电流密度。Under higher current densities, the differential depositing rates lead to a coarser surface. 在较高的局部电流密度下，差异化的沉积率造成表面粗糙。This may affect the mechanical properties of the composite coatings (Ref 7).这可能影响复合镀层的力学性能。 |
