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 ...

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...

Ammrc Tr 68-17 Titanium Carbide Content Effect on Erosion in Cermet Rocket Nozzles

Analyses were carried out on subscale cermet nozzles fired in the AMMRC solid propellant engine at a designated maximum chamber pressure of 1100 psi for nominal burning times of 15 jeconds in order to determine mechanisms of erosion and the effect of the carbide constituent on erosion. The cermet class investigated consisted of an AISI Type 316 stainless steel matrix incorporating a hard phase ...
