Abstract :

[en] Due to the high demand and use of raw cobalt in the field of batteries for electrical cars, it seems interesting to evaluate the use of recycled tungsten-cobalt carbide powder in the hard materials field. The studied material is made from two different powders: a powder composed of raw materials (WC and Co powders mixed together) and a recycled powder (crushed powder containing 7.5 wt% cobalt). The samples are densified by vacuum sintering. The influence of the ratio of recycled powder is discussed by analyzing the density, the phases and the mechanical properties (hardness and toughness) obtained after sintering.
