Systems and methods are provided for applying cold spray erosion protection to an airfoil. One embodiment is a method for applying an abrasion coating to a fiber-reinforced composite substrate. The method includes applying a bond layer to the fiber-reinforced composite substrate by emitting, with a supersonic nozzle of a High Pressure Cold Spray (HPCS) system, a first gas stream including a first metal powder at a first speed below supersonic speed. The method further includes applying a cold spray deposit layer to the bond layer by emitting, with the supersonic nozzle, a second gas stream including a second metal powder at a second speed above supersonic speed.
