Abstract The metal-carbide coating includes a Ni-Cr-Al alloy base layer adhered to metal substrate, a mixed NiCr-Cr3C2 and NiCrAl face layer covering the base layer, and a surface sealing layer of high-temperature organic silicon resin. It can protect overheater against hot corrosion and thus reduce the decrepitation accident of overheater pipe.
