  • Process for the moderately refractory assembling of articles made of SiC-based materials by non-reactive brazing in an oxidizing atmosphere, brazing compositions, and joint and assembly obtained by this process
    Patent number: 10093582
    Abstract: Process for the moderately refractory assembly of at least two articles made of silicon carbide-based materials by non-reactive brazing in an oxidizing atmosphere, in which the articles are placed in contact with a non-reactive brazing composition and the assembly formed by the articles and the brazing composition is heated in an oxidizing atmosphere at a brazing temperature sufficient to melt the brazing composition so as to form a moderately refractory joint, wherein the non-reactive brazing composition is a composition A composed of silica (SiO2), alumina (Al2O3) and calcium oxide (CaO), or alternatively a composition B composed of alumina (Al2O3), calcium oxide (Cao) and magnesium oxide (MgO). Brazing suspension, paste comprising a powder of said brazing composition and an organic binder. Refractory joint and assembly.

  • METHOD FOR ASSEMBLING, BY BRAZING, A SUBSTRATE COMPRISING PYROCARBON WITH PARTS COMPRISING PYROCARBON
    Publication number: 20150165536
    Abstract: A method is provided for assembling by brazing a substrate comprising at least one external pyrocarbon surface with parts such as beads each comprising at least one external pyrocarbon surface. The method includes depositing a brazing material composition consisting of an alloy of one or several metal(s) or metalloid(s) on at least one portion to be assembled of the external pyrocarbon surface of the substrate. The assembly so obtained is also described.
