通过初步筛选和正交优化设计,研制开发出一种新的化学沉积黑镍薄膜工艺,并对槽液各组分对膜层黑度的影响进行了讨论,得出硫代硫酸钠、硫酸锌是黑色成膜的决定因素,复合添加剂具有稳定槽液、提高膜层黑度的作用.最佳工艺条件下得到的膜层呈乌黑色,均匀致密,具有较高的光吸收性能,而且耐大气、中性及碱性介质腐蚀.通过沉积过程的电位测定,确定成膜由初级、次级两个阶段组成. Through the preliminary screening and orthogonal optimization design, a new chemical deposition of black nickel film technology, and the bath components of the film blackness were discussed, the results obtained were sodium thiosulfate, zinc sulfate Is a decisive factor in the formation of black film, composite additives with a stable bath, improve the role of film blackness. The best conditions under the film was black, uniform and compact, with high light absorption properties, but also resistant to the atmosphere , Neutral and alkaline corrosion.According to the determination of the potential of the deposition process, it is determined that the film formation consists of primary and secondary phases.
