摘要
为了解决激光透射难以实现连接聚苯乙烯与钛的问题,采用氧等离子体处理后的聚苯乙烯与经激光表面处理的薄钛进行了激光透射连接。建立了激光透射连接工艺参量的数学模型,分析了工艺参量对连接强度的交互式影响,得到了优化工艺参量。结果表明,经过处理后的聚苯乙烯与薄钛再进行激光连接时,其连接强度从0. 5MPa提高到6. 0MPa以上,有效解决了聚苯乙烯与钛的激光透射连接难题;通过优化工艺参量可获得最优的工艺参量组合。该研究为此工艺的工业应用奠定了基础。
In order to solve the problem that laser transmission was difficult to connect polystyrene and titanium,polystyrene treated with oxygen plasma was used for laser transmission connection with thin titanium treated by laser surface treatment.Mathematical model of laser transmission connection process parameters was established,and interactive influence of process parameters on connection strength was analyzed.The optimized process parameters were obtained.The results show that the bonding strength of polystyrene and thin titanium after treatment increases from 0.5MPa to more than 6.0MPa.Laser transmission connection problem of polystyrene and titanium can effectively be solved.The combination of the optimum process parameters can be obtained by optimizing the process parameters.The research makes the foundation for industrial application of the process.
