Abstract
A quantity of particles () may be cold-sprayed toward the distal surface () of a turbine blade () at a temperature below a melting point of the particles at a velocity sufficiently high to cause at least a portion of the particles to adhere to the surface to form squealer ridge () with a desired cutting profile. The cutting profile may be defined by a face () and a land () disposed at a relief angle () relative to a direction of motion () of a cutting edge (). The ridge may be built by multiple passes of a cold spray gun depositing sequential layers () of varying widths. An in-service blade having worn distal surface may be repaired using this technique.
