摘要 |
A thermal barrier coating adapted to provide a thermally insulating protective barrier on a component, the coating being capable of being applied to the components by spraying methods and being ductile when exposed to high temperatures. The coating comprises a mixture containing constituents of finely divided hollow glass microspheres; a ceramic frit of finely divided particles of alkali silicate titanate glass; and a refractory filler material of finely divided partiles such as micronized mica; aluminum oxide of mullite. All of the constituents of the mixture are suspended in a high temperature resistant binder material such as potassium silicate, sodium silicate or aluminum orthophosphate.
