“…As a result, the relative density and hardness of samples increase with the heating process. It is worthy noting that the soaking time should not be too long, lest secondary recrystallization takes place [23] and reduce the density of the sample.…”

-Sample parts with WC-6Co cemented carbides were manufactured successfully with a novel method called coupled multi-physical-fields (electric field, temperature field and force field) activated sintering technology, using a Gleeble-1500D thermal simulation machine. Effects of sintering temperature on the densification, microstructures and hardness of samples were investigated. It was found that densification of the samples was enhanced with the increase of the sintering temperature and a relative density of as high as 98.76% achieved when a sintering temperature of 1200°C was used. The particle size of the WC in sintered samples increased from 1.837 lm to 2.897 lm when the temperature was increased from 1000°C to 1200°C, resulting in the decrease of the hardness from HRC 63.5 to HRC 61.7. The presented work shows that, potentially, coupled multi-physical-fields activated technology is able to produce hard alloys to meet the engineering applications.

“…Estos valores se asemejan a los obtenidos por Higuera [4 y 18] pero son inferiores a los publicados por Tu [19] y Zhu [20] debido, no solo a defectos locales como porosidad, discontinuidades y microgrietas de origen térmi-co, más abundantes en el recubrimiento con polvo micrométrico, sino también a cambios microestructurales sucedidos durante la proyección. El análisis de los espectros de DRX de las materias primas (Fig.…”

“…Many efforts, such as developing new spray methods [5], minimizing the size of the spray powders [6], have been made to improve the friction properties of WC-Co coating. However, Usmani et al [7], and Stewart et al [8] reported disappointing sliding wear and abrasive wear resistances of nanostructured WC-Co coatings for the increased decarburization.…”
