Title:
ELECTROCHEMICAL SURFACE CLEANING AND PLATING
Document Type and Number:
WIPO Patent Application WO/2018/170843
Kind Code:
A1
Abstract:
Methods and systems for plating a nickel alloy member are described. Methods include submerging a member in a salt solution and establishing a voltage between an electrode and the member such that the member is at a higher electrical potential (positive voltage) relative to the electrode, leading to electrochemical etching of the surface. Following the electrochemical etching, and without removing the member from the salt solution, a second voltage of reverse polarity can be established across the salt solution between the surface and the electrode, leading to electroplating of the surface.
