摘要: Cr3C2-25(NiCr) coating is widely used in wear, erosion and corrosion applications. In the present study, D-gun-sprayed coatings with without 0.4 wt.% ceria incorporated were deposited on Superni 718, Superni 600 Superco 605 substrates. Hot-corrosion runs conducted 40 %Na2SO4-40 %K2SO4-10 %NaCl-10 %KCl environment at 900 °C for 100 cycles. Corrosion kinetics was monitored using weight gain measurements. Characterization of products carried out by field-emission scanning electron microscopy (FESEM)/energy-dispersive spectroscopy (EDS) x-ray diffraction (XRD) techniques. It observed that added both Ni-based alloys showed resistance to under given environment. Addition enhanced adherence oxide during run reduced overall gain. However, Cr3C2-25(NiCr)-coated did not perform satisfactorily this
