- •
The submicron-sized WC particles are bound with WC-Co powders by ball mill method.
- •
The even distribution of WC particles at the interfaces of WC-Co splats is achieved.
- •
The presence of WC particles changes the stress state at the splats' interfaces.
- •
The WC particles at the splats' interface inhibit the propagation of microcracks.
- •
The addition of WC particles enhances the microhardness and sliding wear resistance.
