对添加Cu-Cr络合物的高分子聚合物红外激光诱导表面金属化进行了实验研究,利用1.06μm和10.60μm激光对材料进行表面改性处理,并通过多种表面检测方法对改性后的样品进行了分析。结果表明,1.06μm激光可使材料表面产生大量起到“锚固作用”的微孔,并且样品表面呈现周期性起伏结构,表面增附效果较强,1.064μm激光可打破Cu-Cr络合物的化学键,在改性区域出现还原性Cu1+和Cr3+,含量分别为0.9%和2.8%,激光处理后得到的镀层平均厚为1 100μm,标准差为0.29μm,且镀层附着力较大;而10.60μm激光处理后样品表面呈随机起伏结构,表面Cu1+和Cr3+的含量分别为0.4%和1.6%,镀层平均厚度为1.70μm,标准差为0.59μm,且镀层附着力较小。
The surface metallization induced by infrared laser induced by polymer with Cu-Cr complex was investigated. The surface modification of the material was carried out by 1.06μm and 10.60μm lasers, The samples were analyzed. The results show that 1.06μm laser can produce a large number of micropores which play an important role in the “anchoring effect” on the surface of the material, and the surface of the sample exhibits periodic undulating structure with strong surface adhesion. The 1.064μm laser can break the Cu-Cr complex The chemical bonds of Cu1 + and Cr3 + were found to be reductive in the modified region, with the contents of 0.9% and 2.8% respectively. The average thickness of the coatings after laser treatment was 1 100μm and the standard deviation was 0.29μm, The surface of the sample after 10.60μm laser treatment showed a random undulating structure. The contents of Cu1 + and Cr3 + on the surface were 0.4% and 1.6% respectively. The average thickness of the coating was 1.70μm, the standard deviation was 0.59μm, and the coating adhesion was small.
