| Summary: | This study is about the electrodeposition of Ni-SiC composite coatings at various ultrasonic agitation temperatures (50, 55, and 60°C). The coatings were characterised by a scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS). Vickers microhardness test and immersion test were used to determine the hardness and corrosion behaviour of the composite coating respectively. The immersion test was conducted in 0.5M sulphuric acid to analyse the coating corrosion rate. The results demonstrate that increasing the ultrasonic agitation temperature increase the corrosion resistance of the composite coating. Furthermore, the hardness of the Ni-SiC shows higher hardness values at the highest agitation temperature, 60°C. This shows that Ni-SiC composite coating sample S.60 had the best hardness and corrosion behaviour. |
