COMPOSITE COMPRESSOR IMPELLER WITH AN EROSION RESISTANT COATING AND METHODS OF MANUFACTURING

Impellers made of composite materials with flow path cavities covered by an erosion resistant coating are manufactured by covering removable molds having shapes corresponding to a negative geometry of the flow path cavities, with the erosion resistant coating using plating or thermal spraying. After...

More Information
Summary:Impellers made of composite materials with flow path cavities covered by an erosion resistant coating are manufactured by covering removable molds having shapes corresponding to a negative geometry of the flow path cavities, with the erosion resistant coating using plating or thermal spraying. After shaping and curing a composite material around the molds covered with the erosion resistant coating, the molds are removed, while the erosion resistant coating remains on the composite impeller.
