Abstract

In this research work, carbon nanotubes reinforced Al2O3 coated ASME-SA213-T22 boiler tube steel was investigated for high temperature corrosion behaviour in molten salt environment at 900°C temperature. The coatings were deposited using plasma spray technique and NiCr was used as bond coat before applying CNTs-Al2O3 coatings. The thermogravimetric technique was used to establish kinetics of corrosion. X-ray diffraction (XRD) and scanning electron microscopy/energy-dispersive x-ray analysis (SEM/EDAX) techniques were used to analyse the corrosion products. The CNTs reinforced alumina coatings enhance resistance to corrosion significantly.
