Investigation of Wear Resistance of High Velocity Oxy-fuel Sprayed WC-Co and Cr3C2-NiCr Coatings

Original language description

The comparative investigation of wear resistance was carried out for two types of thermal spray coatings - WC-Co and Cr3C2-NiCr coatings deposited by HVOFspraying process. The wear mechanism was investigated in the interrelationship with wear particles formation. Wear resistance of coatings was evaluated by tribotester FALEX T-09. The wear debris after scuffing were studied by AFM. Metallographical investigation was carried out using optical microscopy and scanning electron microscopy (SEM). X-ray energy dispersion microprobe analysis was used for the investigation of the composition of coatings. The obtained results show that WC-Co coatings are characterized by better tribological characteristics. Wear resistance of coatings was connected with the microstructure.
