摘要

针对铝铜间的物理性能差异以及熔化焊过程中易产生脆性相的特点，提出一种铜铝异质金属冷喷连接的新方法，该方法将纯铝粉末以固态形式高速撞击具有一定坡口的铜铝母材表面，通过粒子与母材、粒子与粒子间的累加成形将铝板和铜板在低于其熔点的情况下实现连接。为了提高接头的力学性能，采用不锈钢颗粒辅助强化方法，利用氮气为加速气体，气体预热温度为270℃，压力为2.4 MPa，Al/Cu冷喷连接接头的力学性能测试结果表明：拉伸断裂在铝母材，接头平均拉伸强度为63 MPa，结合区与铝结合界面平均剪切强度为42 MPa，结合区与铜结合界面平均剪切强度为38 MPa。接头与母材主要通过机械咬合方式连接，不锈钢颗粒的夯实效应使粒子塑性变形增加，提高了接头的致密度和强度，不锈钢颗粒在母材的嵌入钉扎作用可有效提高结合界面的剪切强度。

Abstract

The cold spray bonding method had been applied to connect the pure aluminum and copper in ambient environment under nitrogen gas at 2.4 MPa and 270℃, which can eliminate the brittle intermetallic compounds of welded joints under fusion welding process due to the physical mismatches in densities, melting points and elasticity modules. In this method, solid-state pure aluminum particles with high-speed impacted on the substrate. The stainless steel particles is added in the feedstocks that assisted to improve the mechanical properties of joints. The results of mechanical properties at the bonding joints show that the average tensile strength of bonded joints is about 63 MPa; the average shear strength of Cu-Al and Al-Al bonding interface is 38 MPa and 42 MPa, respectively. The joint is mainly connected to the base metals by mechanical interlocking; the plastic deformation of pure aluminum particles, the strength and density of bonded joints are significantly enhanced with the in-situ tamping effect from the stainless steel particles. The interlocking effect from the stainless steel particles embedded in the base materials can effectively improve the shear strength of the bonding joints.
