Silicon carbide composition for turbine blade tips |
摘要 |
A granular composition is applied to tips of rotor blades utilized in a gas turbine engine wherein the blade tips rub against an abradable ceramic layer. Individual grains each have a core of silicon carbide and a layer of aluminum nitride on the core. A layer of a cladding metal may be bonded to the aluminum nitride. The composition also may include particles of cubic boron nitride and/or particles of metal alloy blended with the grains of silicon carbide.
