摘要：
The operating conditions in power station boilers are conducive to erosion, both in the furnace wall and in the super heater and reheater areas, and these effects cause tube wall thinning and premature failure. The present research work has been undertaken; with an objective to explore the coating potential of Al2O3-3 wt% TiO2 deposited on boiler steel T11 with detonation gun spraying process for erosion resistance. Erosion performance at room temperature as well as elevated temperature by simulating the temperature to actual working conditions of the boilers was evaluated. The eroded samples were analysed with SEM/EDX and optical profilometer.
