To Study High Temperature Erosion-Corrosion of Detonation Gun Sprayed Al2O3 Coated and Uncoated T-91 Boiler steel in Actual Environment of Boiler
Gurkamal Nain Singh, Tarlochan Singh
Erosion and corrosion is the commonly experienced causes of failure at a premature stage of component life, when component subjected under high temperature environment. To achieve higher performance and efficiency of components raise the demand of protective surfaces (coatings). In the present work, a boiler steel T-91 was been taken as a sample material for its erosion-corrosion study in actual environment. Detonation gun thermal spraying process was used for coating of Al2 O3 powder on T-91 boiler steel. The coated and uncoated samples were subjected to cyclic erosion-corrosion in actual environment i. e. in boiler for 10 cycles. The SEM/EDAX and thermo gravimetric techniques were used to analyse the corrosion -erosion products. After the analysis, it was found that Al2 O3 coating was less effective than the uncoated samples of T-91 steel for providing the protection against erosion-corrosion in actual environment of boiler.
