متن کاملInfluence of electrical discharge machining on sliding friction and wear of WC–Ni cemented carbide
Tribological characteristics of fine-grained WC–8 wt%Ni with different surface finishing conditions corresponding to sequential wire electrical discharge machining (wire-EDM) or grinding were investigated by performing dry reciprocating sliding experiments on TE77 pin-on-plate equipment with WC–6 wt%Co as mating material. Surface finishes and wear surfaces were characterized using surface topog...
متن کاملWear Characterization of Cemented Carbides (WC–CoNi) Processed by Laser Surface Texturing under Abrasive Machining Conditions
Cemented carbides are outstanding engineering materials widely used in quite demanding material removal applications. In this study, laser surface texturing is implemented for enhancing, at the surface level, the intrinsic bulk-like tribological performance of these materials. In this regard, hexagonal pyramids patterned on the cutting surface of a tungsten cemented carbide grade (WC–CoNi) have...
متن کاملFRACTURE AND FATIGUE BEHAVIOR OF WC-Co AND WC-CoNi CEMENTED CARBIDES
The fracture and fatigue characteristics of several cemented carbide grades are investigated as a function of their microstructure. In doing so, the influence of binder chemical nature and content (Co and 76wt%Co-24wt%Ni), as well as carbide grain size on hardness, flexural strength, fracture toughness and fatigue crack growth (FCG) behavior is evaluated. Mechanical testing is combined with a d...
متن کاملEDM machinability and dry sliding friction of WC-Co cemented carbides
A number of WC-Co cemented carbides with 6–12 wt. % Co were machined and surface finished by grinding or Electrical Discharge Machining (EDM). EDM was executed in deionised water through several consecutive gradually finer steps. Correlations between Material Removal Rate (MRR), surface finish and EDM parameters were derived. The quality and integrity of surface finishes were analysed by Scanni...
