Microstructure and Structure of LaMnO3/Mn2O3 Film Prepared by Electrodeposition Method

In this study, LaMnO3/Mn2O3 (LMO/MO) film are synthesized using electrodeposition method on SS 316L substrate. The preparation LMO/MO for this electrodeposition was carried out with a concentration of La3+ and Mn2+ between 50 - 150 mM solution. Electrodeposition results show that with a currents variation of 0.1; 0.5; 1; 2.5 mA, LaMnOHx and MnOHx compounds have been formed. It is also observed that an increasing current are followed by increasing in the composition of the La atom. The good thickness of sample occurs at currents of 1 mA. The sample was then heated at 800 degrees C for 4 hours. The X-ray diffraction (XRD) analysis shows that the sample forms LaMnO3 and Mn2O3 phase with ratio composition of 1.79% and 98.21%.
