Nickel chrome coatings mixed with Yttria-Stabilized Zirconia (YSZ) were applied using the High-Velocity Oxy-Fuel (HVOF) method. Three types of coatings were prepared: Ni-20Cr, Ni-20Cr with 5% YSZ by weight, and Ni-20Cr with 10% YSZ by weight. Corrosion tests were conducted on both coated and uncoated samples in a Na₂SO₄-60% V₂O₅ environment at 850 °C, with the samples subjected to cyclic thermal conditions. The experiments were conducted in a silicon tube furnace, with each specimen subjected to 50 exposure cycles. During each cycle, the samples were exposed to a corrosive environment for one hour, followed by a 20-min cooling phase at ambient temperature. The corrosion products were characterized using Energy-Dispersive X-ray Spectroscopy (EDS) and investigated through Scanning Electron Microscopy (SEM). The findings demonstrated a notable enhancement in corrosion resistance when YSZ was incorporated into the Ni-20Cr coatings. Following 50 cycles, the weight gain of the Ni-20Cr, 5% YSZ-Ni-20Cr, and 10% YSZ-Ni-20Cr samples decreased by 70.40%, 82%, and 85.27%, respectively, relative to the substrate.
