文摘
- •
Nickel based MMC coatings were fabricated by wide-band laser cladding.
- •
Coating microstructure was greatly refined by cored-eutectic consisting of cored boride, (Cr,W)23C6 and γ-Ni(Fe).
- •
The growth behavior of cored-eutectic was successfully controlled by adjusting the wide-band laser power.
- •
The wear resistance of composite coatings was promoted to 6.8 times that of substrate steel.
