摘要
A continuous annealing, using the Joule effect, is performed during the fabrication of a tinned copper wire. During this operation, which lasts between 1/10 and 1/100 of a second, the wire is brought in air to a temperature which exceeds the melting point of tin. The influence of the continuous annealing on the nature of the surface layer of the tin coating is studied using XPS. The thickness of the tin oxide film covering the metallic tin is shown to be reduced after the annealing. This result is confirmed by measurements of the electrical contact resistance using the crossed rods method.
