Abstract
The deposition of an amorphous La–Cr–O thin film on a stainless steel was done by radio frequency magnetron sputtering to obtain a protective coating on the metallic interconnect for solid oxide fuel cells. The deposited film was amorphous, but underwent two-phase transformations to the perovskite structure as a result of annealing at 700 °C for 1 h. The first transformation was from amorphous to the monoclinic LaCrO
4 monazite type compound. The second transformation was from LaCrO
4 to orthorhombic LaCrO
3 perovskite. As a result of the phase transformation nano-structured self-assembled dendritic structure was formed with the desired perovskite phase. The structural characterization of the film was done by X-ray diffraction, phase shift microscopy, scanning electron microscopy with energy dispersive X-ray analysis, and micro-Raman spectroscopy.
