Patching process for degraded portion of metallic workpiece e.g. pipe and conduit, involves electroplating reinforcing metallic patch to cover degraded portion

摘要

A reinforcing metallic patch is electroplated to cover the degraded portion without covering the non-degraded portion of metallic workpiece, where the electrodeposited metal of metallic patch has an average grain size of 1000 nm or less. An independent claim is also included for process for in-situ electroforming structural reinforcing layer.
