Topology of WC/Co interfaces in cemented carbides [PDF]
Diffusion Fundamentals, 2023 WC–Co cemented carbides build one of the important classes of metal matrix composites. We show in this paper that the use of machine vision methods makes it possible to obtain sufficiently informative statistical data on the topology of the interfaces between tungsten carbide grains (WC) and a cobalt matrix (Co). For the first time, the outlines of the

Study of the Processing of a Recycled WC–Co Powder: Can It Compete with Conventional WC–Co Powders? [PDF]
Journal of Sustainable Metallurgy, 2021 AbstractCemented carbide tools suffer from many issues due to the use of tungsten and cobalt as raw materials. Indeed, those are listed by the European Commission as “critical raw materials” since 2011 and by the US Department of Interior as “critical minerals” in 2018.
