METHOD FOR TREATING AND STICKING WORK PIECES MADE OF METAL OR A METAL ALLOY COMPRISING A HYDRATED OXIDE AND/OR HYDROXIDE LAYER

摘要

The invention relates to a method for treating an adhesive surface of a work piece made of an aluminium material. The adhesive surface comprises an aluminium oxide layer. The inventive method consists of the following steps; the adhesive surface is cleaned, activated and then at least partially covered with an adhesion promoter. Said adhesion promoter is then fixed by means of post-treating. The invention also relates to a method for sticking components made of an aluminium material. Preferably, an atmospheric plasma is used for cleaning and activating the adhesive surface and for post-treating the adhesion promoter.
