PROCEDE D'ASSEMBLAGE D'UNE PIECE DE METAL ET D'UNE PIECE DE CERAMIQUE, ET DISPOSITIF ELECTRIQUE, EN PARTICULIER CAPTEUR CAPACITIF, REALISE PAR LE PROCEDE
A method for the assembly of a metal part and a ceramic part, including the following steps:supplying a solid ceramic part of the alumina type;supplying a solid metal part, the metal being selected from platinum and tantalum, or an alloy including a majority of one of these metals;depositing at least one layer, called interface layer, on at least one of the solid parts, the interface layer containing magnesium oxide;bringing into contact the solid metal part and the solid ceramic part such that the interface layer is located between the solid parts; andhot densification under pressure of the solid parts brought into contact, to create a close bond between the solid parts and form a spinel from the interface layer. An electrical device, such as a capacitive sensor having a sensitive part produced according to the present method, is also provided.
