Metco 5546NS is a blend of a wear-resistant chromium carbide and a hot corrosion resistant NiCrAlY (nickel-chromium- aluminum-yttrium) alloy. The coating structure produced by Metco 5546NS consists of chromium carbide particles that are finely dispersed in the NiCrAlY matrix. --- The chromium carbide constituent provides excellent high temperature erosion resistance. --- ""
