摘要

In this work, Cu/brass/1015 steel-laminated composites were fabricated via an arc-spraying–annealing–cold rolling–annealing (SARA) process. The microstructural evolution, interfacial characteristics, and mechanical properties of the composites were systematically investigated. The results showed that the as-sprayed coating exhibited significant porosity (9.8%) and a lamellar structure with limited interfacial bonding. The SARA process effectively eliminated porosity (reduced to < 0.24%) and promoted densification, while enhancing interfacial cohesion through mechanical interlocking and the formation of a 2–3 μm interdiffusion layer. Post-treatment induced grain refinement and recrystallization, optimizing the microstructure. Consequently, the final composite achieved a superior strength–ductility balance, with uniform elongation increasing significantly to 46% while maintaining adequate tensile strength. Deep drawing tests confirmed excellent interfacial bonding and co-deformation capability, with no evidence of coating delamination or cracking. This work provides a viable strategy for manufacturing high-performance Cu/steel laminates and offers promising prospects for structural–functional applications.
