Abstract

FeCr alloy were developed as a replacement of ceramic interconnect, they are favored because their moderate oxidation resistance and fairly good corrosion resistance provided by the formation of Cr2O3 scale in the presence of oxidant. Therefore the FeCr alloy compatible for SOFC application. The aim of this project is to conduct the research on the effect of each process in the high temperature oxidation for SOFC application of FeCr alloy. The new process of this research is combining the ball milling process with holding time 15 h, 20 h, 40 h, 60 h, and 80 h, hot pressing at pressure of 25 MPa and temperature of 1000 0C with sample name HP1000, spark plasma sintering at pressure of 10 MPa and temperature of 800 0C and 900 0C with sample name SPS800 and SPS900 and surface treatment via ion implantation by La as implant to obtain material that having good electrical resistance, good microstucture and good in high temperature oxidation for SOFC application. In the ball milling process the smallest crystallite size in milling time 60 h, and the SEM micrograph not identifies the crack and voids in the surface of consolidated specimens. Surface treatment via La-implanted effective to obtain a better result at consolidation process, surface treatment process and electrical analysis than commercial materials. The contribution of La implantation is also essential for the effectiveness of internal to external oxidation transition.
