AbstractNi-SiC composite coating was electrodeposited from the modified bath containing SiC particles. The system consisting of NiSO4 center dot 6H(2)O (35 g/100 mL), NiCl2 center dot 6H(2)O (4 g/100 mL), H3BO3 (3.5 g/100 mL), sodium dodecyl sulfate (SDS) (0.5 g/100 mL) and SiC (0.4 similar to 4.0 g/100 mL) was used at pH=4 and 35 similar to 50 degrees C to obtain a Ni-based composite coating containing SiC particles. The effects of temperature, current density, content of SiC in the electrolyte and ultrasonic dispersion time on codeposited content of SiC particles were investigated. The Ni-SiC composite coating was characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis. The results indicate that the codeposited content of SiC particles increases with increasing of temperature and then decreases at 35 similar to 50 degrees C. When current density is between 0.026 similar to 0.06 A/cm(2), SiC content increases with the increase of current density and then decreases. When the concentration of SiC is between 0.4 similar to 1.0 g/100 mL in the plating solution, it increases with the increase of concentration of SiC. When the content of SiC exceeds a certain value (0.6 g/100 mL), the rate increase becomes low. When the ultrasonic dispersion time is between 10 similar to 50 min, the codeposited content of SiC particles first increases and then decreases with increasing of time. Uniform distribution of SiC particles in the coating is beneficial to refine the grain size of deposit

The system consisting of NiSO_4·6H_2O (35 g/100 mL), NiCl2·6H_2O (4 g/100 mL), H_3BO_3 (3.5 g/100 mL), sodium dodecyl sulfate (SDS) (0.5 g/100 mL) and SiC (0.4~1.0 g/100 mL) was used at pH=4 and 35~50 ℃ to obtain a Ni-based composite coating containing SiC particles. The effects of temperature, current density, content of SiC in the electrolyte and ultrasonic dispersion time on codeposited content of SiC particles were investigated. The Ni-SiC composite coating was characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis. The results indicate that the codeposited content of SiC particles increases with increasing of temperature and then decreases at 35~50 °C. When current density is between 0.026~ 0.06 A/cm~2, SiC content increases with the increase of current density and then decreases. When the concentration of SiC is between 0.4~1.0 g/100 mL in the plating solution, it increases with the increase of concentration of SiC. When the content of SiC exceeds a certain value (0.6 g/100 mL), the rate increase becomes low.
