Abstract: A brazing method for assembling two elements includes selecting two brazing materials that can generate, when they are heated and melted, an intermetallic compound having a melting temperature which is higher than the melting temperature of each of the selected brazing materials taken individually, positioning the two selected brazing materials between the two elements, heating and melting the two selected brazing materials in order to substantially reach the melting temperature of each of the selected brazing materials so as to achieve the precipitation of an intermetallic compound having a melting temperature which is higher than the melting temperature of each of the selected brazing materials taken individually.

Abstract: The present invention relates to a cross-linkable composition comprising: i) a fluorinated ?,?-bis(propargyl) oligomer of formula (I): in which m is 1 to 100, e.g. 1 to 93, n is 2 to 150, e.g. 1 to 128, p is 0 to 2, preferably 0 or 1.75, and n, m and p are selected such that the fluorinated ?,?-bis(propargyl) oligomer of formula (I) has a number average molar mass Mn of 400 to 25000; ii) a cross-linking agent comprising at least three azide-N3 groups; and iii) optionally, a fluorinated oligomer comprising two terminal azide-N3 or fluorinated ?,?-bis(azide) oligomer groups. The invention also relates to a material comprising the click chemistry reaction product of the cross-linkable composition of the invention, to a method for preparing said material and to the uses thereof.

Abstract: A method for manufacturing a strip of impregnated anodized aluminum, for use in a coil of an electrotechnical component, said coil including an interstitial material providing dielectric cohesion and insulation functions, said interstitial material being suitable for cross-linking, in other words for forming, by chemical reactions between the components thereof when subjected to certain physical conditions, molecular structures being organized in a lattice, the method comprising: a step of applying the precursor mixture of said interstitial material to the anodized aluminum; at least one step of cross-linking the precursor mixture in order to form said interstitial material on the strip of aluminum; wherein the anodized aluminum has not been subjected to the sealing of the pores of the alumina formed by anodization prior to the application of the precursor mixture of said interstitial material.
