Abstract

The steam oxidation resistance of 80Ni-20Cr coatings on modified 9Cr-1Mo steel has been evaluated in the temperature range of 600 °C to 750 °C. High-velocity oxyfuel (HVOF) spray was used for the coating process. The steam-oxidized specimens exhibited the diffusion of iron from the substrate to the coating and diffusion of nickel from the coating to the substrate. Nickel diffusion to the substrate adjacent to the coating induced the microstructural changes. Micro X-ray diffraction (XRD) studies and energy-dispersive spectroscopy (EDS) point analysis on these transformed zones revealed that the newly formed phases are the austenite in the high-Ni-concentration region and the martensite in the low-Ni-concentration region. Microhardness studies showed higher hardness values in the martensite zones.
