Anodic Process of Cemented Carbide

Development of Creep-Resistant Tungsten Carbide Copper Cemented Carbide

Fine-grained tungsten carbide copper (WC-Cu) cemented carbide was sintered via spark plasma sintering at 1773K using a fine WC powder with a mean particle size of 0.11 mm. The mechanical properties were compared with tungsten carbide cobalt (WC-Co) cemented carbide and a binderless WC-sintered material. The Vickers hardness and fracture toughness obtained by the indentation fracture method for ...

Development of Cemented Carbide Tool of Reduced Rare Metal Usage

Cemented carbides, including coated cemented carbides, account for 75% of the cutting tools market because of their features such as high hardness, toughness, and the responsiveness to iron, through the use of tungsten carbide for their main hard phases and cobalt for their bonding metals. The consumption of tungsten continues to increase as the amount of carbide tool production increases with ...

Influence 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...
