Title: | High temperature oxidation behavior of a novel Ni-20Cr alloy powder coating on T22 steel |
Authors: | Kumar, M. Singh, H. Singh, N. |
Issue Date: | 22-Nov-2021 |
Abstract: | Ni-20Cr alloy powder synthesized by the investigators was deposited on T22 boiler steel by high velocity oxy-fuel (HVOF) spraying process. High temperature oxidation behavior of uncoated and coated samples was studied under cyclic air oxidation conditions at 900C for 50 cycles in a silicon carbide tube furnace. The kinetics of oxidation was established using weight change measurements for the uncoated and the coated boiler steel. The oxidation products were studied using different characterization techniques, which include SEM/EDS and XRD analyses. Ni-20Cr coating was found to be successful to enhance the oxidation resistance of the steel. |
