چکیده

The start of melting as well as the melting range in WC-Co and WC-Ni hardmetals is significantly influenced by the alloy gross carbon content as well as by additives (V, Cr). Both Vanadium and Chromium significantly lower the start of melting but also broaden the melting range, in particular at low carbon content (formation of M6C-phases). As a result, a certain temperature range can be defined in which the metallic alloy binder (Co, Ni) is only partly (and not fully) molten during the isothermal sintering process.

Effect of Carbide Particle Size on the Microstructure, Mechanical properties, and Wear Behavior of HVOF-sprayed WC-17% Co Coatings

This study investigates the effect of carbide particle size on the microstructure, mechanical properties, and abrasive wear resistance of WC-17%Co HVOF-sprayed coatings. The characteristics of WC-1, WC-2, and WC-3 coatings with carbide sizes of 1 µm, 0.9 µm, and 0.5 µm, respectively, were also investigated. WC-1 coating experienced the maximum carbon loss of 42%, while WC-2 and WC-3 coatings un...

Interfaces between Model Co-W-C Alloys with Various Carbon Contents and Tungsten Carbide

Interfaces between alloys simulating binders in WC-Co cemented carbides and tungsten carbide were examined on the micro-, nano-, and atomic-scale. The precipitation of fine WC grains and η-phase occurs at the interface of the alloy with the low carbon content. The precipitation of such grains almost does not occur in the alloy with the medium-low carbon content and does not take place in the al...

Evaluation of Microstructure and Mechanical Properties of Ti6A14V / (WC-Co) Friction Welds

The metallurgical and mechanical properties of Ti6Al4V/(WC-Co) friction welds have ben investigated. The microstructure close to the bondline comprised a mixture of acicular and equiaxed α plus β phases. The diffusion of elements in the welded specimens has been detected. The fracture strengths of Ti6Al4V/(WC-Co) friction welds markedly improved when the cobalt content in the (WC-Co) carbide su...
