Abstract Ti-alloy is widely used in aeroengine, sodium nitrate solution (NaNO3) and sodium chloride solution
(NaCl) are widely used in electrochemical jet machining (EJM). This paper Focused on the machining performance of Tialloy
with the use of EJM. At first, the two kinds of electrolytes were tested on Ti-alloy with different surfaces. Then the
processing quality was explored by analyzing the channel aspect ratio (depth/width), channel surface roughness (Sa), oxide
percentage and surface topography. At last the two kinds of electrolytes were used in EJM in different orders again, and the
excellent order was confirmed. Those two tests provided academic and experimental basis for the improvement of EJM on
Ti6Al4V.
