The Bond between Steel and Copper through Intermediate Zine layer in Copper - Clad Steel Rod

Abstract
The copper-clad steel rod was prepared by drawing of a zinc electroplated steel rod clad in a copper tube and it was subsequently heat treated in a salt bath to enhance the bonding force between different metal layers. The thickness of electrodeposited zince layer and the time and temperature of heat treatment were the main variables investigated. Their effects on the bond strength were discussed on the basis of results of tensile test, microstructures, microhardness test, and fracture surfaces.
