Hardness, fracture toughness, and wear resistance are strongly inter-related properties of cemented tungsten carbide. Higher hardness usually dictates higher wear resistance but at the cost of fracture toughness. A new dual composite of WC-Co, named DC carbide, is reported in this article.

Kinetics and oxidation behavior of laser clad WC-Co and Ni/WC-Co coatings
Ceramics International, 2018Abstract In this study, the oxidation behavior of WC-12Co and electroless Ni/WC-Co coatings is investigated by Thermogravimetric analysis (TGA), X-Ray Diffraction (XRD), and scanning electron microscope (SEM). Time dependence of weight gain showed a linear behavior for WC-Co coating and a parabolic-like behavior for Ni/WC-Co coating. This behavior is

Nanoindentation of WC–Co hardmetals
Journal of the European Ceramic Society, 2013Abstract WC–Co cemented carbide has been investigated using instrumented indentation with maximum applied loads from 0.1 to 10 mN. The hardness and indentation modulus of individual phases and the influence of crystallographic orientation of WC on the hardness and indentation modulus have been studied.

An algorithm is described for the calculation of a conventional elastic limit for WC-Co alloy in compression taking into account residual thermal stresses in its phases. The algorithm is based on the equations of thermoelasticity of two-phase composites. Comparison of theoretical and experimental results points to their fair agreement.

ABSTRACT Operating conditions for maximum removal rate were established using a wire electrical discharge machine (EDM) with pulse type power supply. Material removal was primarily by vaporization and melting of cobalt followed by the dislodging of WC grains. The resolidified liquid smears the surface cracks and decreases the surface roughness.

Abstract The composite of tungsten carbide–cobalt (WC–Co) is a very important material used in carbide dies, cutting tools and components under erosion. The machining of this material is very difficult because of its very high hardness. Among conventional methods, this material can be machined with pendulum grinding method when special and expensive ...
