ABSTRACT:
In order to minimize a clearance between a turbine and its housing, and thus, improve the efficiency of a turbine engine, an abradable coating can be applied to an inner surface of the turbine housing. However, there are no known abradable coatings that can be applied to a housing that is subjected to temperatures between 950–1500° F. for extended periods of time. The apparatus of the present disclosure includes a housing including a 950–1500° F. section in which at least one rotating blade row is positioned. The rotating blades and the 950–1500° F. section each includes a surface being comprised of a relatively non-abradable material. The surface of the housing comprised of the relatively non-abradable material is covered by a 950–1500° F. relatively abradable coating that includes a metallic matrix and at least one of a thermoplastic and dry lubricant. The metallic matrix is 55–85% of the coating by volume.
