“…The SiC particles are irregularly distributed on the surface of the composite coating without any obvious agglomeration. This should be attributed to the fact that the addition of SiC particles increases the number of nucleation sites of Ni crystals while effectively inhibiting the growth of Ni grains [10,45]. Gyawali et al [46] and Huang et al [16] described the similar structural morphology of Ni-SiC coating prepared by electrodeposition methods.…”

“…The surface of the 2218 aluminum alloy disc samples (φ 50 mm × 8 mm) was polished using 400, 600, 800 and 1000 grain metallographic sandpapers in a certain order [10,40]. The surface roughness was measured to be ~0.22 µm with a TR 200 surface roughness meter with an accuracy of 0.001 µm (Beijing Saiboruixin technology Co., Ltd., Beijing, China).…”

“…Figure 6 shows the surface microhardness and bonding strength of experimental samples. The hardness is often used to evalu ate a material's wear resistance, cutting and scratching properties [10,[47][48][49]. To investi gate the effect of surface microhardness on its tribological properties, the microhardness of experimental samples is measured.…”

“…The research of surface coating technique, which reduces wear and improves service life and reliability of industrial equipment by preparing a protective coating on the contact surface, has aroused great interest [3][4][5]. Laser cladding [6], chemical/physical vapor deposition [7,8], plasma spraying [9] and electrodeposition [10] are all commonly used as surface coating techniques to enhance wear resistance of materials. Among these methods, the electrodeposition method has received much attention owing to its low cost, ease of implementation and applicability to various geometries [11][12][13][14][15].…”

Among the preparation methods of functional coatings, the electrodeposition technique has attracted much attention due to its advantages of economy, high efficiency and good structural adaptability. The application of aluminum alloy materials is greatly limited due to their poor friction reduction and wear resistance. Therefore, to enhance the tribological behaviors of aluminum alloy materials, the Ni-MoS2, Ni-SiC and Ni-MoS2/SiC composite coatings were prepared on the 2218 aluminum alloy by an electrodeposition technique. The prepared composite coating samples exhibited a compact and dense microstructure, which was consistent with the result of their high microhardness. No obvious microcracks and defects appeared at the interfaces, indicating that the composite coating samples had good adhesion to the substrates and can effectively improve the frictional shear resistance. The results of wear experiment showed that the wear rate, friction coefficient and friction response time of all composite coating samples were lower than that of the substrate sample. However, the friction reduction and wear resistance of the same composite coating sample were not consistent. The friction coefficient of the Ni-MoS2 composite coating sample was the lowest, and the wear rate of the Ni-SiC composite coating sample was the lowest. According to the worn surface observations, the wear mechanism of composite coating samples was mainly characterized by the mild abrasive wear, flake spalling, tearing and pits caused by particle shedding, and the substrate sample showed a severe adhesive wear and abrasive wear.
