ABSTRACT:
The invention concerns the manufacture of a porous product based on nickel, hromium, tungsten, molybdenum, iron, cobalt or an alloy of these metals. The porous product is characterized on one hand by the fact that it comprises 85 to 99.5% by weight of the base material and 15 to 0.5% of a fusible auxiliary metal chosen from among tin, indium, gallium, germanium and mixtures and alloys of these metals and, on the other hand, by the fact that the base material is in the form of elementary particles such as powders, fibers or chips, bonded to each other by means of diffusion brazing.
