Study on hydration of titanium base alloys during electrochemical machining

The surface hydration of parts and tool electrodes, manufactured from the same blank during electrochemical machining in electrolytes (15%NaCl) is investigated. It is shown that hydration of surfaces in tool electrodes of VT15, VT14 alloys is considerably lower than the surface hydration of parts made from the same alloys. It is pointed out that the degree of hydration greatly depends on the effectiveness of destruction of protective films on titanium alloys
