Abstract��TC4 titanium alloys were electropolished in 5% perchloric acid ethanol solution and the corresponding electropolishing curves were obtained. With the increase of the electropolishing temperature�� the decomposition voltage at inflexion derived from the electropolishing curve decreased at first and then increased�� which reached its minimum at 20 ��. The effects of experimental parameters ��temperature�� voltage�� stir and polishing duration�� on the surface morphology of alloys had been studied via the field emission scanning electron microscope��FE-SEM��. The results showed that the best experimental parameters were as follows�� polishing temperature of 20 �棬 voltage of 28 V�� current density of 0.98 A/cm2�� stir�� and polishing time of 25 s.
