Abstract

The invention is a metal tube such as a heat exchanger tube which has been treated by in situ electrodeposition to repair one or more degraded sections. The repaired metal tube section has an electroformed structural layer which has an ultrafine grain microstructure of sufficient thickness to restore the degraded section at least to its original mechanical specifications.
