Formation of a molybdenum silicon suboxide: growth of SiO2 pegs.
J Mater Sci Lett 1986 May; 5(5):513-515
The high-temperature, long-term oxidation resistance of a low- chromium, silicon-molybdenum-iron alloy has been shown to result from the formation of a sio2 suboxide layer. This layer at the metal-oxide interface was observed by removing the substrate metal via chemical etching. Scanning electron micrographs of the oxide surface at the metal-oxide interface showed the presence of suboxide pegs extending into the substrate metal. A time sequence for the oxidation process of the alloy is presented.
