Description
Summary:A dense and conductive LaCrO3 coating was prepared on type 316 stainless steel （316 SS）, aiming at exploring its potential appli-cations in SOFC and in other high temperature environments. Powder of LaCrO3 with perovskite structure was synthesized by sol-gel method. LaCrO3 coating on 316 SS substrate was obtained by slurry coating technique. The microstructure of the coating on 316 SS after sintering in air at 800 and 900 ℃ for 200 h was characterized. The effect of LaCrO3 coating on oxidation resistance of the steel in air was also investi-gated. The results showed that the coating was adhesive to the substrate and improved greatly the oxidation resistance of the alloy.
