Abstract
Copper and Cu-based alloy coatings suppress carbon transfer to the metal surface from carbon-supersaturated gaseous environments. The metal dusting resistance of such coatings has been investigated in CO-H2 gas mixtures at temperatures ranging from 450°C to 700°C. Conventional plating and cladding methods have been employed to deposit Cu-based materials on the surfaces of commercial materials such as 2.25Cr-0.5Mo steel and carbon steel. In addition to the performance of Cu-based materials under laboratory conditions, the effect of alloying elements such as Sn, Zn, Ni and Al in Cu on the corrosion process and the coating/substrate interface stability are discussed with particular attention to commercial scale applications.
