Inconel 718-Silicon Carbide Composite coatings for BHEL Nozzle component
Ceramic Division, BHEL, Bangalore
The team at BHEL’s Ceramic Division visited the surface engineering laboratory. They were satisfied with the Thermal Spray facilities, and briefed the team at the research domain on the various erosion problems in their current coal burner nozzles.
Severe Erosive wear of inner surfaces of coal burner nozzle leading to higher maintaining cost and frequent power shut down .
High quality Inconel 718-Silicon Carbide Composite coatings were developed using optimized thermal spray parameters by HVOF process on BHEL Nozzle component.
Based on the positive results of the tests conducted at ceramic division, BHEL, Bangalore placed orders for coating their nozzle component.
