To provide a composition, a system and a method that apply an erosion-resistant protective coating to a substrate exposed to a high temperature and erosion environment.
The coating (12) composition includes a cermet material having metal carbide phase particles with an average size of less than 5 microns. The coating (12) has an average surface roughness of less than approximately 5 microns. The system (10) for applying the coating (12) to the substrate includes a spray gun (16) configured for use with a high velocity oxygen or high velocity air fuel system. The system (10) further includes a cermet material supplied to the spray gun (16), wherein the cermet material includes at least approximately 34 percent by weight of a metal carbide phase having an average particle size of less than or equal to approximately 5 microns. The metal carbide phase is dispersed in a liquid selected from the group consisting of water, alcohol, an organic combustible liquid, or an organic incombustible liquid.
