A process (30) for the repair of a component part (36,66) incorporating a cold spray process step (50) for depositing material particles (54) to fill a discontinuity (40) in the part surface (42) or to create a desired surface geometry (78) on the part (66).

A process (30) for the repair of a component part (36,66) incorporating a cold spray process step (50) for depositing material particles (54) to fill a discontinuity (40) in the part surface (42) or to create a desired surface geometry (78) on the part (66). The cold spray process may be controlled to provide a grit blasting effect prior to depositing the material in order to remove contaminants (48) from the surface of the part. The material deposited (56) by the cold spray process may form a joint (78) between an insert (72) and the part (66). The process may be used to repair parts made of directionally solidified (DS) or single crystal (SC) base material (44) without causing a re-crystallization of the base material. The process may further be used to deposit repair material (56) over a braze material (22).

1. A process for repairing a component part, the process comprising the steps of:identifying a discontinuity in a part surface; excavating material from the part surface proximate the discontinuity to form a repair surface comprising a brazed material; and directing particles of a repair material toward the part at a velocity sufficiently high to cause the particles to deform and to form a mechanical bond but not a chemical bond to the brazed material.
