Abstract

The process of thick-layer electrochemical copper plating of VT6 titanium alloy has been tested as an alternative to the traditionally used chromium repair technology for restoring the geometric dimensions of worn parts. A method is presented for preparing the surface of titanium alloys for the deposition of a copper coating and the results of a study of the properties of a copper coating with a thickness of more than 100 μm obtained from a copper-plating pyrophosphate electrolyte based on potassium pyrophosphate. The adhesion strength of a copper coating with a titanium substrate is compared with a standard chromium coating.
