Effect of the Solid Concentration in the Suspension on Electrophoretic Deposition (EPD) Coating Parameters

Abstract:

In this study, electrophoretic deposition (EPD) method was used for biphasic calcium phosphate (BCP) coating on 316L stainless steel substrates, using ethanol as a dispersive medium. Deposition was achieved on the cathode at 30 V in 30 seconds at room temperature in variable concentrations (0.5, 0.8, 1, 1.25, 1.5g of BCP powder). After deposition, the coated substrates were sintered at 800 °C for 1 hour. The phase purity and structure of the synthesized powders were checked by X-ray diffraction (XRD). The morphology, structure and phase composition of the coatings were investigated by scanning electron microscopy (SEM) and energy dispersive spectrometer (EDS). The results show that deposition weight and thickness increased with increasing concentration. Furthermore, increases in cracks and changes in morphology on coating surfaces as concentration increased at the constant applied voltage during electrophoretic deposition were observed.
