논문 초록 (Abstract)
Oxidation behavior of Si pack cementation coatings on a three-phase Mo−Si−B alloy was examined. During Si pack cementation of a three-phase Mo−Si−B alloy, a MoSi2 outer layer was synthesized on the exterior layer. Following oxidation in air of the pack-coated alloys at 1200°C, the MoSi2 phase layer was consumed and replaced by the Mo5Si3 (or T1) phase. The synthesized T1 phase provided excellent oxidation resistance when exposed to high temperatures. The silicide-coated alloys exhibit higher oxidation resistance compared with uncoated Mo−Si−B alloys. The enhanced oxidation behavior and its mechanism are discussed in terms of the thicknesses of the oxide layers under exposure to high temperatures.
