摘要: Five ZrO2-based composites (ZrO2-WC, ZrO2-TiCN and ZrO2-TiN grades) five WC-Co cemented carbide grades were machined by wire-EDM tested on a linearly reciprocating sliding pin-on-flat tribometer PLINT TE77 in dry conditions against WC-6wt%Co pins. Measurement of friction coefficient penetration depth due to wear was performed continuously. The results revealed strong influence the secondary phase, surface finish, chemical mechanical properties tribological characteristics carbides. WC10Co(Cr/V) displayed superior resistance compared other grades. lowest encountered with ZrO2-WC.
