Beschreibung
Zusammenfassung:	The invention concerns a thermal barrier coating system (12) requiring no bond coat adherence high temperature heat treatment and having enhanced insulating capabilities such that it may be applied to gas turbine engine components of varied shape, thickness and size. In preferred embodiments, the system includes a metallic bond coat which does not require a bond coat adherence high temperature heat treatment to form a bond between the metallic bond coat and a metallic substrate to which it is applied. A porous ceramic insulating layer is deposited on the metallic bond coat. In another preferred embodiment, the porous ceramic insulating layer is deposited directly on the metallic substrate. The coating system is particularly advantageous for insulating metallic components prone to distortion in heat treatment and those requiring insulation in an as machined condition.
