Oxidation Study of APS Thermal Barrier Coatings in Elevated Temperatures

Article Preview

TBCs is a type of multilayer systems, mainly used in the thermal parts of aero engine, acting as the part of heat insulation. The using temperature of parts can be improved because of the being of TBCs. TBCs is one of the most advanced high temperature coatings, and it has many perfectly properties, including the chemical property at high temperature, anti-erode and thermal insulation [1,2]. If TBCs spall from the base, the base will expose in the high temperature, then, rapidly destroy. TBCs generally include three layers, superalloy, bonding layer, insulation layer, and the thermally grown oxide (TGO) between the bonding layer and insulation layer. Justly because of the being of TGO, the TBCs easily failed [3,4]. Although many researchers studied the oxidation of TBCs, the investigation of the relations between oxidation and oxide temperature has not been done by far. So, the work put the emphases on the discussion of APS TBCs’ oxidation property in different temperatures by experiment.
