Abstract

Coating systems for a cooled turbine blade tip, such as a metal turbine blade tip, are provided. The coating system includes an abrasive layer overlying the surface of the turbine blade tip. One or more buffer layers may additionally be disposed between an outer surface of the blade tip and the abrasive layer. The coated blade tip can be used with a ceramic matrix composite (CMC) shroud coated with an environmental barrier coating (EBC) to provide improved cooling to the tip so as to lengthen oxidation time of the abrasive layer and reduce blade tip wear. Methods are also provided for formingthe cooled blade tip and applying the coating system onto the cooled turbine blade tip.

Description

technical field [0001] The subject matter disclosed herein relates to turbine blade tip wear, and more particularly, to cooling turbine blades including coating systems and methods for eliminating turbine blade tip wear in conjunction with CMC or metal shrouds in gas turbine engines. Background technique [0002] The turbine section of a gas turbine engine includes a rotor shaft and one or more turbine stages, each turbine stage having a turbine disk (or rotor) mounted or otherwise carried by a bearing and a perimeter mounted to and extending radially from the disk of turbine blades. Turbine assemblies typically generate rotating shaft power by expanding hot compressed gases produced by the combustion of fuel. Gas turbine blades or vanes generally have an airfoil shape designed to convert the thermal and kinetic energy of flow path gases into mechanical rotation of the rotor. [0003] In a turbine engine, a shroud is a ring of material that surrounds the rotating blades. ...
