Effect of Surface Treatment on the Bonding Performance of Liquid Solid Composite Copper Alloy/Ductile Iron Bimetallic Interface
The bonding performance is a key factor in whether copper/ductile iron bimetallic materials can be used under harsh conditions.This article uses different surface treatment methods to prepare copper/ductile iron bimetallic materials.Perform microstructure and elemental analysis of the joint microstructure through SEM,EDS,etc.,and carry out corresponding mechanical property testing and analysis.The results indicate that the normalizing process can reduce or remove graphite particles on the surface of ductile iron.The melting process allows molten copper to penetrate into the graphite grooves,increasing the bimetallic interface performance and enhancing the interface bonding strength.
