抄録

It is well known that the adhesion strength of metal plating film on Al substrate should be remarkably improved by introducing double zincate treatment as a pretreatment process for metal plating on Al. At each step of alkaline etching, desmutting, the first zincate treatment, HNO₃ dipping, and the second zincate treatment in the double zincate process, depth profiles and the chemical state of the surface elements were extensively measured by XPS. A set of surface structure models in the process was proposed to explain the improvement of the adhesion strength by double zincate treatment.<br>By dipping the first zincate film in HNO₃ solution, a granular zinc deposit of about 1 μm thickness, roughly deposited on Al passivation film at the first zincate treatment, was dissolved, and zinc nano-particles were believed to be concurrently formed in the Al passivation film of about 3nm thickness. In the second zincate treatment the nano-particles should be exposed to the second zincate solution to act as nuclei for formation of a highly uniform and thin zinc film. The zinc particles were so close to the metallic Al substrate, that Dipolar coupling such as Al^δ+…O^δ&minus…Zn^δ+ would act to improve the adhesion strength of double zincate film on Al substrate.
