Abstract
The invention relates to an anodic bonding method for bonding two elements with an intermediate layer. The invention especially, but not exclusively, relates to an anodic bonding method for between a metallic element and a heterogeneous element, for example a glass, artificial sapphire or ceramic element. The specificity and aim of the present invention is to produce an assembly that is gas-tight and fluid-tight, solderless, brazing- or welder-free and without organic compound (glue). The present method has multiple industrial applications, including making it possible to attach a watch-glass, typically made of mineral glass, sapphire or transparent or translucent ceramics, to a bezel or case middle of a watch case using the anodic bonding technique.
