摘要
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。
In this paper,the influences of laser power,irradiating time,compositions,and concentration of plating solution on chemical localized depositions of nickel have been studied by using 1079.5nm Nd:YAP laser as inducing light source,and common ceramic as substrates.The physical mechanism of laser action has been discussed in brief.The micrographs and contours of the deposited spot have been analyzed by SEM and Profile Meter.The results show that the deposition induced by laser has many advantages,such as smooth surface,regular shape and size, even and compact distribution,compared with common chemical plating,the plating speed could be 2~3 order of magnitude higher than that of common chemical plating,and the thickness of deposited spot has a Gaussian like distribution in transverse direction.
