  "abstract": "This study investigates the microstructural and high-temperature oxidation behaviour of SA516 boiler steel coated with Ni-20Cr, Ni-20Cr+40TiC, and Ni-20Cr+40TiN using High Velocity Oxygen Fuel (HVOF) and Plasma Spray (PS) techniques. The cyclic air oxidation tests were performed for fifty cycles at 900°C in a simulated laboratory environment, and the resulting microstructural and phase changes were analyzed by means of X-ray Diffraction (XRD), Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEM/EDS), and X-ray mapping. The uncoated SA516 steel experienced intense spalling and cracking of the oxide layer, developing an unprotected phase (Fe 2 O 3 ). Among all coatings, the HVOF-sprayed Ni-20Cr+40TiC coating diminished maximum weight gain by 95.71% compared to bare SA516 steel, indicating superior oxidation resistance. This enhanced performance of coatings is attributed to formation a dense, protective oxide layer consisting of Cr 2 O 3 , TiO 2 , NiTiO 4 , and NiO, coupled with reduced porosity and enhanced microhardness.",
