The present study examines the hot corrosion behavior of carbon nanotube (CNT)reinforced zirconium-yttrium coatings on T-91 boiler tube steel in a molten salt environment consisting of Na₂SO₄–60 wt% V₂O₅ at 600 °C under cyclic conditions. The coatings were
fabricated using the air plasma spray technique. Uncoated and coated specimens, along with all as-coated samples, were exposed to hot corrosion in a silicon tube furnace at 600 °C for 50 cycles. Corrosion behavior was assessed by measuring the mass gain after each cycle. The corroded products were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive X-ray analysis (EDAX).
