Summary: | A particular type of steel has a higher concentration of carbon than other types of steel called carbon steel. This
study focused on the electrodeposition coating of Nickel Silicon Carbide (Ni-SiC) composite coating at 50 oC. In this study,
medium carbon steel was used as a substrate. 25 g/l SiC was used during the deposition. The carbon steel was acted as the
cathode and the carbon rod as an anode during electrodeposition. The coated sample was heat-treated at 350 OC for 1 hour.
Scanning Electron Microscope (SEM) was used to analyze the surface morphology and microstructure of the coated and
heat-treated sample before and after the wear test. The coated sample's element composition and phase distribution are
determined using the Energy Dispersive Spectroscopy (EDS) and X-Ray Diffraction (XRD). To identify the hardness of
the composite coating, Vickers micro-hardness test was used on the surface of the sample with 100g load in 10 seconds
with ten indentations. Weight loss method was conducted to determine the average wear resistance of the sample. The wear
behavior of the Ni-SiC was evaluated using the weight loss method with 3 g/l alumina as the abrasive material. The results
showed that the heat-treated coating had higher wear resistance than the without heat treatment. The findings also showed
that the sample with the heat-treatment process had a higher hardness. This proved that the heat-treated sample had the best
wear behavior and hardness value compared to without heat treatment due to denser coating produced |
