| dc.description.abstract | Coating SUS316L stainless steel is essential to address its limitations in medical applications. While it offers strength, corrosion resistance, and affordability, it is not fully inert in the harsh environment of the human body. Thus, for this experiment, the objective is to fabricate SUS316L coated calcium carbonate (CaCO3) via electrophoretic deposition technique. This project also aims to investigate the effect of current voltage, time and polyvinyl alcohol (PVA) percentage on the formation of CaCO3 coating on SUS316L. The process starts from sample and suspension preparation. Then electrophoretic deposition (EPD) was done followed by characterizations such as, X-Ray diffraction analysis (XRD) for phase characterization, scanning electron microscope (SEM) for morphology observation, energy dispersive X-ray (EDX) for elemental analysis and surface roughness measurement. Based on SEM results, higher voltages agglomerate more CaCO3, while increasing the time increases the amount of CaCO3 coated onto the substrates and 2% of PVA produced more uniform coating compared to 1% PVA. In conclusion, higher voltage agglomerates more CaCO3 coating while increasing the time from 30 minutes to 60 minutes increase the amount of CaCO3 coated onto the substrates and higher percentage of dispersant such as PVA contribute to more uniform coating. All of this proved that the deposition coating can be easily modified by either adjusting the voltage, the deposition time and the percentage of PVA. Additionally, coating proven when the surface roughness value increases after coating. | |
