Abstract

Abstract The oxidation of a Sm(Co 0.68 Fe 0.22 Cu 0.08 Zr 0.02 ) 7.5 magnetic alloy deposited with a thin Al 2 O 3 film has been studied. The Al 2 O 3 -coated alloy exhibits almost no oxidation at 500 °C and only forms a few-micrometers-thick internal-oxidation-affected zone (IOAZ) at 600 and 700 °C for 20 h exposure to air. The effect of the Al 2 O 3 film on the oxidation degradation of magnetic phases of the alloy is disclosed based on microstructural characterizations of the IOAZ. The result also shows that the Al 2 O 3 film offers better protection than the Cr 2 O 3 film reported previously.
