ABSTRACT:
The invention relates to a process and an apparatus for the metallic impregnation of a substrate that is in the form of a web of conductive fibres, in which the said substrate is placed in an inert atmosphere that is under partial vacuum (chamber 1), a potential difference is created between the said substrate (cathode) and a metal for impregnation in the said atmosphere, the metal for impregnation is supplied in molten form into the said atmosphere and is maintained at its vaporization temperature by heating.
The invention is of use in the manufacture of semi-finished products for the aeronautical industry.
