摘要：
A method of forming a generally planar part for a jet engine is provided. The part is adapted for withstanding high thermal stress but not high mechanical stress. A preformed strip of a superalloy is mounted around a drum shaped mandrel. A low pressure plasma deposit of a different superalloy is formed on the preformed strip. The strip is demounted and mechanically straightened.
