文摘
- •
Ni-P/nano-WC composite coatings were treated by electrical contact strengthening (ECS).
- •
Metallurgically bonded composite coatings with low porosities and fine grains were obtained after ECS.
- •
The coating microhardness increased with increasing contact current.
- •
The microhardness distribution of the Ni-P/nano-WC composite coating became more uniform after 20 kA ECS.
- •
The wear resistance of the Ni-P/nano-WC composite coating increased with increasing contact current.
