Dotted matrix structures on Ti6Al4V surfaces with different spacing were manufactured by laser technology. The low surface energy materials were deposited on above Ti6Al4V substrates by self-assembled technique in order to prepare hydrophobic/superhydrophobic surfaces. The static contact angle and roll angle of all specimens were measured by self designed measuring system. The moving process of drop dripping was recorded by high speed camera system. The results indicate that the hydrophobic/superhydrophobic surfaces can be gained by dotted matrix structure manufacturing and self-assembled technique, and the contact angle decreases with the spacing of dotted matrix increasing. The static contact angle is relevant to the height of drop dripping, and depends on the drop volume and the last dripping height. The spreading coefficient of drop on the horizontal surface is determined by the roughness and static contact angle, the bigger the roughness and static contact angle is, the smaller the spreading coefficient. With the increase of slope angle, the spreading coefficient decreases and the jump distance increases. The movement of drop dripping on slope surfaces is greatly influenced by the dripping height, roll angel and slope angle.
