Nickel is a metal with high tensile strength, toughness and corrosion resistance, and is a popular choice as an MMC that hard and soft reinforcements could be dispersed on it, while improving its wear, anti-friction and corrosion resistances. As the earliest model of its type, Guglielmi’s model is based on a two-step process involving loose and strong adsorption of the particles. Several models for studying co-deposition of particles in metal matrices could be found in the literature for example, Guglielmi’s and Celis’s models. In addition, electrodeposition as a low-cost technique has a high deposition rate that leads to homogenous distribution of the particle. Under ambient pressure and temperature, electrodeposition is one of the most important techniques used for producing composites. There are several routes to prepare and form MMCs, i.e., squeeze casting, hydrothermal methods, powder metallurgical methods, high-velocity oxygen fuel thermal (HVOF) spraying, physical and chemical vapor deposition (PVD and CVD) and electrodeposition. MMCs have been used in various fields ranging from high-tech industries (e.g., electronic components and computers) to more traditional industries (e.g., general mechanics and automobile, paper mill, textiles and food industries). Copper, aluminum, chromium, zinc, cobalt, iron and nickel act as common matrix materials, with a wide variety of inert particles such as carbon fiber, TiO 2, ZNO, SiC, Al 2O 3 and SiO 2 as reinforcement. Generally, MMCs could be classified into three different microstructures, namely particle-reinforced MMCs, short-fiber or whisker-reinforced MMCs and continuous-fiber or sheet-reinforced MMCs. MMCs have been under consideration over the past decades, due to their superior properties such as wear and corrosion resistance, hardness, thermal, electrical and magnetic properties, in comparison with pure metal or alloy coatings, have attracted significant attention in the protective coating industry. Metal matrix composites (MMCs) could be described as a class of composite materials with two constituents: a metallic matrix that consists of dispersed inert particles. The materials should be robust and light while offering a combination of several desired mechanical properties such as wear resistance, hardness, self-lubrication (in some cases), and heat resistance while providing good corrosion resistance at the same time. Nowadays, the need for the properties of construction materials is increasing. The results showed that Ni–SiO 2 composites prepared in the presence of ALES had better corrosion resistance, hardness and wear properties. Furthermore, the addition of ALES into an electrolyte bath negatively supercharged silica surfaces and increased silica dispersion, which led to a dramatic increase in the silica incorporation percentages to around 14 v%. CTAC was found to lead to entrapment mode silica co-deposition in the Ni coating. In fact, upon increasing the internal stresses, the products prepared in the presence of CAPB and DG were found to crack to some degree. The effect of the presence of four surfactants, namely cocamidopropyl betaine (CAPB), decylglycoside (DG), cetyltrimethyl ammonium chloride (CTAC) and ammonium lauryl ether sulfate (ALES), on overcoming this problem was investigated in this research, and the surfactants were found to greatly influence the surface charge of silica, silica incorporation percentage and the microstructure of the composite. The incorporation of hydrophilic silica particles into the Ni composite coating during co-electrodeposition is so difficult due to the small size and the hydrophilicity of SiO 2 particle, generally less than 2 v% of silica is incorporated into the composite at different current densities, agitation speeds and silica concentrations. This article presents a method for the electrochemical preparation of a coating of nickel–silica nanocomposites on a carbon steel substrate.
