Metal dusting is described as a severe form of corrosion attack in which iron, steels, nickel- and cobalt-based alloys disintegrate into metal or metal carbide particles in a coke deposit when exposed to strongly carburising gases (carbon activity ac>1) at elevated temperatures (300-800°C). Despite intense research efforts, which led to much progress in mitigating metal dusting, particularly in the oil and gas industry, the complete prevention still remains an issue. Current study focuses on measuring corrosion resistance of heat-treated austenitic Ni, Ni-Cr-based complex alloy compositions containing iron and copper as additional alloying elements.
