A composite material, a fiber reinforced enamel, has been formulated to repair metallic components damaged by corrosion. This material bonds chemically to the corroded metallic substrate and can be applied in a furnace or in the field by an acetylene torch. Fibers are added to the enamel to increase fracture toughness and help relieve thermal cycling stresses. An important factor in determining if an enamel is successful is evaluating its resistance to corrosion. Two tests have have been found to effectively compare different coatings in their resistance to erosion and cavitation corrosion.
