The study of ternary carbides formation during SPS consolidation process in the WC-Co-steel system
(ELSEVIER SCI LTD, 2009)
Tungsten carbide has a wide range of applications, mainly cemented carbides made of WC and Co, as wear resistant materials. However, the high cost of WC-Co powders encourages the use of a substrate to manufacture a ...
Estudo da substituição do cobalto pela liga Invar no metal duro com base em carbeto de tungstênio
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA MECÂNICA, 2020-01-27)
Cobalt is the most widely used binder in tungsten carbide (WC) -based hard metals
due to its properties, mainly wettability. However, this metal can cause toxicity problems,
and, in addition, it has a high production ...
Corrosion behavior of WC-Co coatings deposited by cold gas spray onto AA 7075-T6
(2018-01-01)
This work reports a morphological, mechanical, and corrosion resistance characterization of WC-12Co and WC-25Co coatings deposited by cold gas spray (CGS) onto AA 7075-T6 alloy. Cross-sectional images of the coatings ...
