Abstract

Arc plasma treatments of Fe-Co-Ni alloy using Ar, Ar-Cl₂, Ar-N₂, Ar-O₂, Ar-Cl₂-N₂ and Ar-Cl₂-O₂ arc plasmas with varying O₂ flow rate were examined. Large amounts of fumes were formed when Ar-Cl₂-N₂ and Ar-Cl₂-O₂ plasmas were used. The Fe component was separated selectively from the alloy using Ar-Cl₂, Ar-Cl₂-N₂ and Ar-Cl₂-O₂ plasmas with a small concentration of O₂, while the Co component was separated using Ar-Cl₂-O₂ plasmas with a high concentration of O₂. The separation of Fe components was attributed to the selective chlorination of Fe. The separation of Co was attributed to both the chlorination of Co and the oxidation of Fe.
