Orthogonal experiment on the preparation of hydrophobic Ti6Al4V surface by WEDM

Abstract

The surface roughness of the hydrophobic titanium alloy was obtained by using the electric spark wire cutting (Ti6Al4V) technology. The surface of the titanium alloy was measured and characterized by means of ultra depth of field microscopy, scanning electron microscopy and contact angle measurement. The pulse width, the number of power transistors (peak current) and feed speed parameters were optimized by orthogonal experiment, and the influence of these parameters on the wettability of Ti6Al4V surface was discussed. The results show that when the pulse width is 32μs, the number of the power tube is 4, the feed rate is 50 μm/s, the contact angle of Ti6Al4V is preferably 142 degrees.
