PROCESS FOR TIN COATING A METALLIC SUBSTRATE, PROCESS FOR HARDENING A TIN LAYER AND WIRE HAVING A TIN COATING

摘要

The present invention is directed to a process for tin coating a metallic substrate, and a process for hardening a tin layer and wire having a tin coating The invention relates in particular to a process for tin coating a wire. In the process, firstly a tin layer is applied, and a metal layer made of a metal different to tin is applied thereto. Then, the layers are subjected to a diffusion annealing operation.
