Formation of ultrasonic spot welded Cu/Cu NPs/Cu joints and the mechanical properties and electrical resistance

To enhance the mechanical properties and reduce the electrical resistance of ultrasonic spot welded (USWed) Cu/Cu joints, Cu nanoparticles (NPs) interlayer was added between the two Cu sheets. The results showed that, as the welding time increased, the cavities in the Cu NPs interlayer and at the in...
