摘　　要：为了探究微沟槽阵列对TC4(Ti6Al4V)钛合金表面润湿性的影响规律,使用皮秒激光在钛合金表面进行微槽加工。设计正交试验并进行回归分析研究激光参数与沟槽尺寸形貌之间的关系。通过单因素实验,分别改变槽宽、槽深以及槽间距,研究沟槽形貌尺寸的变化对钛合金表面水接触角的影响。结果发现在一定范围内,更大的槽宽和槽深、更小的间距会增强钛合金表面的疏水性能。In order to investigate the influence of micro groove arrays on the wettability of TC4(Ti6Al4V)titanium alloy surface,microgroove machining is carried out on the surface of titanium alloy using picosecond laser.Orthogonal experiments are designed and regression analysis is performed to study the relationship between laser parameters and groove size and morphology.Through single factor experiments,the effects of changes in groove width,groove depth,and groove spacing on the water contact angle of titanium alloy surfaces are studied.It is found that within a certain range,larger groove width and depth,and smaller spacing can enhance the hydrophobicity of the titanium alloy surface.
