Opis:: Metallic oxide layer of heat resistant element contributes to the high-temperature oxidation resistance by delaying the oxidation, and also has positive effect on the electrical resistivity increase. In this study, the green compacts of Fe-Cr-Al powder mixed with STS434L were oxidized at 950°C up to 210 hrs in order to consider the effect of metal oxide on the oxidation and electrical resistance. It exhibited the low oxidation resistance in case of 434L only, however it increased as the amount of Fe-Cr-Al powder in the 434L compact. The higher electrical resistivity was observed at the Fe-Cr-Al compact with and 434L powder. The metal oxides of (Fe_0.6C_0.4)₂O₃, Cr₂O₃, and Fe₂O₃ contributed to the electrical resistivity, whereas Al₂O₂ took a role of oxidation resistance.

Opis:: In order to improve the high-temperature oxidation stability, a study of 434L sintered stainless steel was focused on the effect of addition of metallic oxides to form stable oxide film on the inner particle surface. In this paper, oxidation behavior of 434L compacted parts in accordance with the addition of metallic oxides were discussed with high temperature oxidative reaction, and sintering behavior analysis under 950°C. Oxidation weight gains of 434 L have increased as a form of parabolic laws. The hightemperature oxidation resistance was improved by the mixed addition of amorphous SiO₂ and silica up to 2wt.%. The oxidation rate was decreased and kept constant after 60 hours. It was caused by the restraint succeeding oxidation due to the stable oxide formation of Cr₂SiO₄ phases on the particle surface to prevent densification and inhibition the external diffusion of Cr. High-temperature stability was confirmed by the electrical resistivity maintains the constant value of 1.3×10^-2 Ω ·cm when the silica added less than 2w/o to 1w/o A-SiO₂ added 434L.
