Effect of CeO₂ on the Microstructure and Properties of Thermal Spray Welded FeNi Coatings

Abstract:

FeNi self-fluxing alloy powders and CeO₂ were flame spray welded onto carbon steel, bonding strength investigations of the coating/substrate systems were conducted. The microstructure of the coatings was analysed by a field emission gun scanning electron microscope(FEGSEM), with attached energy dispersive spectroscopy(EDS). The result showed that with the addition of CeO₂, the microstructure of the coatings are refined compared with that without CeO₂. The mechanism of the microstructural refinement by the addition of CeO₂ is dicussed in this paper.
