Abstract

Tungsten carbide hardmetals have been widely used for against wear due to their high hardness and strength with compromised toughness as well as self-lubricating properties. However, engineering conditions are always much more complicated. Corrosion is one of the common damages encountered. This study aimed to understand the effect of a different binder on fundamental properties and corrosion behavior of WC based HVOF coatings. Three kinds of coatings, each with a different binder, were prepared using commercial feedstock powders, i.e. WC-12Co, WC-10Co4Cr and WC-12Ni. Micro Vickers hardness tester, XRD and SEM were used. The corrosion performance was evaluated using a salt spray tester. It was found that the WC-10Co4Cr coating showed the highest corrosion resistance and superior hardness comparable to the WC-12Co coating.
