利用CO2 激光 (λ =10 .6 μm)作为诱导光源 ,普通玻璃作为衬底 ,研究了影响激光沉积质量和速率的因素 ,探讨了激光诱导液相化学沉积技术的反应机制 ,反应产物及其沉积模型等。采用光学显微镜对其沉积过程和沉积铜的微观形貌进行了观察。结果表明 :激光诱导液相化学沉积技术能沉积出表面平整 ,颗粒大小均匀、规则 ,分布致密的铜镀层 ,且沉积速率比起普通化学镀也要高出几个数量级。
The factors affecting the quality and rate of laser deposition were studied by using CO2 laser (λ = 10. 6 μm) as the light source and ordinary glass as the substrate. The reaction mechanism, reaction products and deposition of laser-induced liquid phase chemical deposition Model and so on. Optical microscopy was used to observe the deposition process and the morphology of copper deposited. The results show that laser-induced liquid chemical deposition can deposit copper coating with smooth surface, uniform particle size, regular and dense distribution, and its deposition rate is several orders of magnitude higher than that of ordinary electroless plating.
