Abstract
A dense and conductive LaCrO3 coating was prepared on type 316 stainless steel (316 SS), aiming at exploring its potential applications 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 °C for 200 h was characterized. The effect of LaCrO3 coating on oxidation resistance of the steel in air was also investigated. The results showed that the coating was adhesive to the substrate and improved greatly the oxidation resistance of the alloy.
