Microstructure and cavitation-silt erosion behavior of two HVOF-sprayed hardfacing coatings for hydro-turbine applications

Microstructure and cavitation-silt erosion behavior of two HVOF-sprayed hardfacing coatings for hydro-turbine applications

The cavitation-silt erosion (CSE) has caused severe technical challenges and economic losses to the hydro-turbine operated in silt-laden river. In this manuscript, two hardfacing (i.e., WC-20(Cr3C2)-7Ni and Cr3C2-25(NiCr)) coatings were manufactured via a high-velocity oxygen fuel (HVOF) spraying me...
