Abstract
A process ( ) for the repair of a component part ( ) incorporating a cold spray process step ( ) for depositing material particles ( ) to fill a discontinuity ( ) in the part surface ( ) or to create a desired surface geometry ( ) on the part ( ). The cold spray process may be controlled to provide a grit blasting effect prior to depositing the material in order to remove contaminants ( ) from the surface of the part. The material deposited ( ) by the cold spray process may form a joint ( ) between an insert ( ) and the part ( ). The process may be used to repair parts made of directionally solidified (DS) or single crystal (SC) base material ( ) without causing a re-crystallization of the base material. The process may further be used to deposit repair material ( ) over a braze material ( ).
