Abstract
Alloys and metals get corroded when exposed to high temperature in air or in actual boiler environment in thermal plants. In the present study, a Ni-20Cr coating was deposited by detonation gun process on ASTM–AS-213, T-11 boiler steel. Cyclic corrosion studies were carried out in molten salt environment at 900°C for 50 cycles. Each cycle consist of 1 hour heating in Silicon carbide tube furnace followed by 20 minutes cooling in air. The kinetics of weight gain or loss was measured after each cycle and visually examined, the surface studies of the exposed samples were characterized by SEM/EDS and XRD analysis. The results obtained showed the better performance of Ni-20Cr coated T-11 boiler steels than the uncoated T-11 boiler steel.© 2014 The Authors. Elsevier Ltd.
