Abstract

Filters, transpiration cooling elements, heat-exchange materials, bearings, electric brushes, magnetic circuit elements and so on are made by suspending metal fibres in a liquid medium, matting the fibres and bonding them e.g. by melting a coating of brazing alloy previously applied to the fibres, or by sintering, if desired, after compacting the mat. The fibres may be matted by deposition on a travelling web, by slipcasting in a porous mould or by depositing the fibres on the outside of a porous core immersed in the slurry, a partial vacuum being applied to the interior of the core. Sintering temperature are 38-75 DEG C. higher than for powders of the same materials. More than one layer of material can be deposited, if necessary using a magnetic field to orient one layer in a different direction. Fe, Mo, Ni and stainless steel are specifically mentioned as fibre material and copper may be used, as the brazing metal.ALSO:Filters, transpiration cooling elements, heat-exchange materials, bearings, electric brushes, magnetic circuit elements and so on are made by suspending metal fibres in a liquid medium, p matting the fibres and bonding them e.g. by melting a coating of brazing alloy previously applied to the fibres, or by sintering, if desired, after compacting the mat.
