Abstract Scope |
The recycling of cemented carbides at the end of their product life cycle is of particular economic, ecological and strategic importance. These composite materials, mainly consisting of tungsten carbide embedded in a Co binder, can be recycled by the so-called zinc process. This research investigates the disintegration of cemented carbides in an excess of liquid zinc in dependence of the WC grain size as well as the Co content of the material, temperature and duration. The data indicate highest disintegration rates at low grain size, average Co content and temperatures as well as a high duration regarding the experimental limits. Therefore, this study provides insight concerning the recyclability of certain cemented carbide grades and discusses the ongoing phenomena. |
