Patent ID: 7222775

Claim:
A process for the metallization with a silicon alloy melting at a temperature T1 of certain zones of the surface of a part made of an oxide ceramic unable to be wetted by said alloy, said oxide ceramic being an alumina-based ceramic and said alloy being a mixture of silicon and at least one metal element chosen from Co, Zr, Ti, Rh, V, Ce, Cr, Re, Ru, Y, Hf, Ir and Ge, said process comprising, in succession, the following steps: deposition of carbon on the said zones to be metallized of said part; deposition of the silicon alloy in solid form on at least one portion of said part, so that said alloy has at least one point of contact with said zones to be metallized; and heating to a temperature greater than or equal to Ti, said alloy thus gathering in the molten state on the said zones to be metallized.
