Cavitation and Sand Slurry Erosion Resistances of WC-10Co-4Cr Coatings
Source abstract
Abstract
Two WC-10Co-4Cr coatings were deposited by high-velocity oxygen fuel (HVOF) and high-velocity air fuel (HVAF) spray processes, respectively, and their basic mechanical properties, cavitation and sand slurry erosion resistances were investigated. The results show that the HVAF-sprayed WC-10Co-4Cr coating exhibited a lower degree of decarburization and better properties in terms of hardness, fracture toughness, porosity, cavitation and sand slurry erosion resistances than those of the HVOF-sprayed WC-10Co-4Cr coatings, respectively. Therefore, HVAF-sprayed WC-10Co-4Cr coatings may be better employed for the protection of hydro-turbine component surfaces against cavitation and sand slurry erosion.
