Definitions
- the invention relates to a method for the currentless production of corrosion-protective layers on aluminum components, in particular on hollow body components with a honeycomb structure.
- protective layers of zinc or zinc-containing alloys to aluminum. This can be done, for example, by metal spraying, by galvanizing or by roll cladding. Although the methods lead to good adhesion and mechanical resistance of the protective layer, they are relatively complex.
- Chromating and phosphating processes are also known, with the aid of which top layers can be applied to aluminum.
- solutions made from monozinc phosphate, phosphoric acid and fluoride are used.
- the resulting layers are about 1-5 f ⁇ m thick and soluble in acids and alkalis. They are therefore mainly used as a primer for paints and plastic coatings.
- the layers are protected with a thin, clear methacrylate or cellulose acetate coating, since otherwise there is a risk of corrosion attack (see Wernick, Pinner, Zurbrügg and Weiner "The surface treatment of aluminum", p. 193 ).
- the object of the present invention is to develop a method for producing corrosion-protected components in which the coatings are relatively easy to manufacture, have high wear resistance and corrosion resistance.
- Zincate solutions of this composition are generally known.
- the surface treatment of aluminum p. 501 indicated a similar composition, this zincate solution being used to achieve thin layers of zinc for subsequent galvanization.
