Abstract

AbstractIn this research work, carbon nanotubes reinforced Al2O3 coated ASME-SA213-T22 boilertube steel was investigated for high temperature oxidation behaviour at 900ï‚°C temperature inthe air. The coatings were deposited using plasma spray technique and NiCr was used asbond coat before applying CNTs-Al2O3 coatings. The hot corrosion studies were conducted onuncoated as well as plasma spray coated specimens in air at 900°C under cyclic conditions.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 Aluminacoatings enhance resistance to corrosion significantly.Keywords: Oxidation, thermal spray, carbon nanotubes, boiler steel, XRD, SEM/EDAXCite this ArticleRakesh Goyal, Buta Singh Sidhu, VikasChawla.
