摘要

Titanium alloy Ti6Al4V is frequently used in the aerospace and other industries. In order to attainTi6Al4V with a high surface quality, the present study examined the use of side-flow electrochemicalmachining, paying particular attention to the relationship between the feed rate and the averageprocessing current, balance gap, and surface roughness. Using electrochemical machining channeldesign and analysis, the surface topographies of titanium alloys, electrochemically machined withdifferent current densities, were investigated. The results showed that, with increasing feed rate, theaverage processing current increases linearly, while the surface roughness decreases rapidly. When thefeed rate is increased to 1.8 mm/min, the balance gap is very small; thus, there is a risk of short-circuit.Simultaneously, with a rapid rise in the current density, the amount of corrosive pitting increased, withthe area covered gradually expanding until the activation sites joined together and overlapped eachother. Thus, the surface quality of the titanium alloy improved.
