Abstract

In the present study, the effect of Explosive Welding Stand-Off Distance on the structure and Corrosion behavior of aluminum alloy 5083-copper joint is studied. The microstructure was examined by optical microscopy and scanning electron microscopy and Corrosion behavior with potentiodynamic polarization tests and electrochemical impedance spectroscopy in a salt environment. Microscopic results showed that as the stand-off increased from 1. 5 to 2. 5 mm, the joint Interface changed from smooth to wavy, and the local melting thickness increased in the joint Interface. Comparing the results of the energy distribution spectroscopy, it was found that the concentration of aluminum in the local melting zones of the Interface increases with increasing Stand-Off Distance. There are also cracks perpendicular to the joint in the local melting zone. As the stopping distance increases, the Corrosion rate increases, which is due to the increase in kinetic energy and plastic deformation in the joint Interface, changes in the concentration gradient, and increase in the thickness of the local melting layer.
