中文摘要：

烘烤炉高温烧结固化是传统的聚四氟乙烯（PTFE）、聚全氟乙丙稀（FEP）、聚全氟代烷氧基聚合物（PFA）涂层制备工艺。针对传统工艺的诸多缺陷,提出激光辐照固化技术。在室温空气条件下,利用1070 nm连续光纤激光辐照系统取代原有高温烘烤固化工艺来制备三种氟聚合物涂层。同时,通过控制激光扫描路径,制备出图形化的PTFE、FEP、PFA氟聚合物涂层,得出制备三种涂层的最佳工艺参数。分析发现制备机理是利用激光的热效应,使三种涂层膜处于熔融状态,发生交联固化而成。

英文摘要：

Baking oven sintering technology is the traditional method to prepare polytetrafluoroethylene（PTFE）,fluoroethylenepropylene（FEP） and polyfluoroalkoxy（PFA） coating. In order to solve the drawbacks of the traditional technique, a new preparation method by laser sintering is presented in this paper in which the PTFE、FEP and PFA coating are prepared by 1070 nm continuous fiber laser irradiation replacing traditional hightemperature baking oven curing process. Meanwhile, by controlling laser scanning path, the preparation of the graphical PTFE、FEP、PFA coatings is achieved. The optimized processing parameters are obtained. Analysis indicates that the preparation mechanism is based on the thermal effects of laser energy input, which induces the original powder sprayed layer turn into molten state then promotes the crosslinking curing for the formation of the coating. The whole process acts as physical change without any changes of chemical composition of the material.
