ABSTRACT:
The object of the invention is to provide a thermal barrier coating system for protecting metal surfaces at high temperature in normally corrosive environments.
The thermal barrier coating system includes a metal alloy bond coating, the alloy containing nickel, cobalt, iron, or a combination of these metals. The system further includes a corrosion resistant thermal barrier oxide coating containing at least one alkaline earth silicate.
The preferred oxides are calcium silicate, barium silicate, magnesium silicate, or combinations of these silicates.
