Plasma Sprayed Functionally Graded and Layered MoSi2-Al2O3 Composites for HighTemperature Sensor Sheath Applications

摘要

Protective sensor sheaths are required in the glass industry for sensors that areused to measure various properties of the melt. Molten glass presents an extremely corrosive elevated temperature environment, in which only a few types of materials can survive. Molybdenum disilicide (MoSi2) has been shown to possess excellent corrosion resistance in molten glass, and is thus a candidate material for advanced sensor sheath applications. Plasma spray-forming techniques were
