Abstract: A method for coating an LSM powder onto an SOFC metal interconnector using a plasma spray process is provided to improve the physical property of a final spraying material by adding an excessive amount of volatile material during a powder manufacturing process. In a method for coating an LSM powder onto an SOFC metal interconnector, a mixture powder is produced by mixing La2O3, SrCO3 and MnCO3 powders together, wherein an excessive amount of Mn containing powder is added to the mixture powder. The mixture powder is calcinated and a solid-phase reaction is performed relative to the mixture powder. Then, a wet milling process is performed relative to the powder to obtain slurry. The slurry is changed into powder by using a spray drying process. A sand blasting process is performed on a base material which is to be coated. The powder is coated onto the base material using a plasma spray process.
