为了提高钛合金薄板与复合材料之间的粘结性能，需要对钛合金薄板进行激光毛化处理，重点在于找到合适的激光加工工艺参数。对各个参数采用单因素轮换法进行实验，结果表明，在选取适当的保护气体侧吹角度、气压的情况下，激光输入电流、脉冲宽度、离焦量对毛化点微观形貌的影响最直接；重复频率、加工速度的影响次之。此外通过在显微镜下研究毛化点的微观结构，总结出各个激光参数对毛化点平均直径、微凸起高度及材料的表面粗糙度的影响，并得出了相关的规律。

In order to improve the bonding performance between the ti -alloy sheet and composite materials , it disposes the ti-alloy sheet using laser texturing .The main technological parameters that influence laser texturing effect are investigated.The study on the processing parameters of the textured spots morphology shows that ,the input current , pulse width and defocusing amount are the ultimate affection under the appropriate protective gas side angle and pressure , the pulse frequency , processing speed are the weak influence .Based on the microstruc-ture under the microscope , it summarizes the influence of each laser parameters to the average diameter , the height of the micro projection and the surface roughness , and then obtains the best technological parameter.
