In a gas turbine engine, a method and apparatus for containing molten materials and ignited titanium and titanium alloys within the confines of the turbine engine environment. The method includes the step of first applying a bond coating to the inner surface of the outer compressor casing. The bond coating is then plasma oversprayed with a non-reactive, thermally insulative ceramic top coating. The apparatus includes a substrate having a bond coating and a ceramic top coating, surrounding at least a portion of the gas turbine engine, for containing turbine engine fires within the turbine engine environment. Preferably, the bond coating is a Ni--Co--Cr--Al--Y alloy, and the top coat is stabilized zirconia.

[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [1.] In a gas turbine engine, having a substrate surrounding at least a portion of the engine, the substrate having a solid inner surface and an outer surface, a method for preventing a burning material expelled from the engine from penetrating the substrate, comprising the steps of:spraying a bond coating directly onto the inner surface of the substrate; andapplying an insulative thermal barrier coating onto the bond coating, the barrier coating having a melting temperature higher than an expected temperature of the burning material and higher than a melting temperature of the substrate.
