Abstract
A method for repairing a Ni-based alloy component includes preparing a surface of the Ni-based alloy component for receiving a cold spray repair; spraying a stream of particles onto a the surface of the Ni-based alloy component to form a coating thereon; and removing any over-spray on the surface of the Ni-based alloy component. The particles are formed from an alloy material having a melting point such that the particles are sprayed at a spray temperature that is less than the melting point of the alloy material.
