SEM image of a sol–gel derived composite presenting WC grains (grey phase) embedded in a Fe binder matrix (dark phase). The crystalline composites are prepared from amorphous sol–gel masses containing W, Fe alkoxides and ...

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 ...

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 ...

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 ...

The performance assessment as to water consumption in WC cisterns has contributed to the development of flushing system technologies, which allow smaller flushing volumes. The purpose of this work is to assess the performance ...
