Changes in Structure and Corrosion Resistance of Cryogenically Treated WC-Co Cemented Carbides
Original language description
Deep cryogenic treatment (DCT) of WC-Co cemented carbides (CC) was experimentally explored. Four types of cemented carbides were studied. They had different WC grain sizes and the volume fractions of the cobalt binder. Some specimens were deep-cryogenic-treated (DCT) at -186°C in dry vapour of liquid nitrogen. Another group of specimens was tempered at 450°C. The corrosion resistance of treated specimens was then determined by potentiodynamic testing in artificial mine water. Microstructural changes were characterized with the aid of X-ray diffraction analysis. DCT-treated specimens showed a higher corrosion resistance than the untreated ones and than those which were only tempered. X-ray diffraction analysis revealed that DCT changed the ratio of ε-Co and α-Co phases. The extent of these transformations was dictated by the carbide phase grain size and by the volume fraction of cobalt.
