Effect of Ni Addition on In Situ WC-Cr3C2 Cermet Coating by Laser Controlled Reactive Synthesisuse

Abstract:

Article Preview

WC-Cr3C2 cermet coating on carbon steel was fabricated by laser controlled reactive synthesis and exhibited the metallurgical bonding at the interface between coating and substrate. Experimental results show that addition of Ni results in a significant change on phases and microstructure of coating. Ni addition remarkable improves resistance to thermal shock of coating. This is accounted for by increasing planar crystal zone of the coating due to Ni addition, which decreases stress concentration at the interface.
