One of the most technological to develop and adhere to the catalysts on the FeCrAl substrate are based on electrophoretic deposition. The objectives of this research is to investigate the coating thickness on FeCrAl metallic material for catalytic converter. The electrolyte prepared with distilled water, at a constant temperature of 40±50C, and pH value is 5 using HCl and NaOH reagent. A nickel (Ni) plate substrate acted as anode with dimension of 50 mm x 10 mm, whereas a FeCrAl acted as cathode with dimension of 40 mm x 20 mm. The electroplating was conducted for several times of 15, 30, 45, 60 and 75 minutes, current density of 8 A/dm2 and 3 g γ-Al2O3 inserted into the beaker for each sample. Coating thickness analysis on cross section of the coated samples were carried out using Scanning Electron Microscope (SEM)-Energy Dispersive Spectroscopy (EDS). The result shows that the UBdEL samples has lowest coating thickness of 5µm, the coating thickness of Electroplated FeCrAl increased for 11.3µm and the highest coating thickness signed by UB+EL samples for 12µm. Higher coating thickness potential to increase the thermal stability due to protective oxide layer on FeCrAl substrate material.
