利用 10 79 5nmNd:YAP激光作诱导光源 ,普通陶瓷作为基体 ,研究了激光功率、辐照时间、镀液组份、浓度对激光诱导化学局域镀覆金属镍的影响规律 ,探讨了激光作用的物理机制。利用扫描电子显微镜及轮廓仪分析了镀斑形成过程、微观形貌、厚度分布。结果表明 :与普通化学镀相比 ,激光诱导的镀覆速度要大约两个数量级 ,镀层表面平滑、颗粒大小均匀、规则、分布致密。镀斑的厚度在横向上呈类高斯分布。
The effects of laser power, irradiation time, bath composition and concentration on the laser-induced chemical local plating of nickel were investigated by using 10 79 5 nm Nd: YAP laser as the light source and ordinary ceramic as the substrate. The effects of laser action Physical mechanism. The formation process, microstructure and thickness distribution of the coating were analyzed by scanning electron microscopy and profile analyzer. The results show that the laser induced coating rate is about two orders of magnitude faster than that of conventional electroless plating, the surface of the coating is smooth, the particle size is uniform, the rules are dense and the distribution is dense. Plaque thickness in the horizontal direction was Gaussian distribution.
