Friction stir processing (FSP) is a material processing technique recognized to enhance the mechanical properties of the material owing to micro-structural refinement. In the present study, the feasibility of the use of ...

In the current work, Ni–Al2O3 based composite coatings were fabricated using High Velocity Flame Spray (HVFS) system. The effect of alumina content on the microstructure and various mechanical properties viz. microhardness, ...

Performance of hydropower plant is severely affected by the presence of sand particles in river water. Degree of degradation significantly depends on the level of operating parameters (velocity, impingement angle, ...

Performance of Ni–Al2O3 based composite coatings was evaluated under slurry erosion condition. Erosion resistance was correlated with different properties of the coatings. It was observed that fracture toughness is an ...

Hydroturbines and other fluid machineries are generally subjected to cavitation and slurry erosion environment resulting in the degradation of impellers, vanes, nozzle, spear, labyrinth seal, and buckets. Although hydroturbine ...
