激光透射连接工艺在生物医学植入体及其封装中具有良好的应用前景。使用半导体连续激光器进行了0.1 mm厚医用聚对苯二甲酸乙二酯(PET)薄膜与0.1 mm厚薄钛板之间的激光透射连接实验,分别采用单工艺参数和双工艺参数进行全面实验对连接接头质量进行分析,并使用光学显微镜对不同工艺参数情况下的接头形貌进行观测。在实验基础上,通过单工艺参数分析得到了PET薄膜与薄钛板激光透射连接的工艺参数,这可为激光透射连接时提供合理的工艺参数范围;通过双工艺参数分析得到了主要工艺参数对连接接头质量的影响,这可为激光透射连接时选取适当的工艺参数以提高加工效率。

Laser transmission joining of dissimilar and biocompatible materials has potential application in biomedical implants and their encapsulation process. 0.1 mm thick PET films and 0.1 mm thick titanium are joint using laser transmission joining technology. The effects of main laser parameters including laser power,scanning speed on joint quality are investigated by using analysis of variance. The results show that laser transmission joining can be used to join PET films and titanium. Based on the research,laser transmission joining of PET film and titanium process window is obtained;it will be helpful for the premise of guarantee of joint quality.
