Dear researcher
I have made a tensile bond test of Ni-4TiO2 and NI-TiO2-Al2O3 coating deposited by HVFS. The application is for protection against slurry erosion in hydro turbine. After tensile bond test adhesive coating failure was observed for Ni-TiO2 and glue failure was observed for Ni-TiO2-Al2O3. If i want to predict the coating performance which one is better for the barrier against slurry erosion ?
