The current study explores the effects of SiC co-deposition in Ni matrix during pulse electrodeposition (PED) at various pulse frequencies. X-Ray Diffraction (XRD) analysis indicates that at lower frequencies, the composite coating favours the (111) plane orientation, while at higher frequencies (50 and 100Hz), it changes toward the (200) plane. Scanning Electron Microscopy (SEM) analysis shows a decrease in SiC particle content with increasing frequency. Coatings deposited at 10Hz display a compact, uniform structure with higher SiC particle concentration, resulting in smoother surfaces compared to pure Ni coatings. This leads to higher hardness (440 HVN) compared to coatings deposited at higher frequencies (425 HVN and 410 HVN for the 50Hz and 100Hz, respectively). Furthermore, the composite coatings exhibit superior corrosion resistance, with reduced electrolyte penetration and localized corrosion relative to pure Ni. Notably, the 10Hz coating demonstrates a lower corrosion rate of 0.005mm/year and a higher corrosion protection efficiency of 88%. Therefore, SiC co-deposition at 10Hz acts as a protective barrier, inhibiting corrosion progression and enhancing long-term durability against corrosion.
