    摘要: The invention relates to a method for fabricating an open-porous metal foam body with a nickel base alloy, to a metal foam body fabricated this way as well as advantageous applications for the separation of specific components and pollutants from fluid flows. On the occasion, according to the set object open-porous metal foam bodies which have improved mechanical properties, and in addition an enlarged specific surface and/or increased surface roughness are to be provided. During fabricating it is proceeded such that an open-porous base foam body made of nickel or a nickel base alloy is coated with a liquid binding agent. Subsequent to this, a mixture of a powdery nickel base alloy and an organic component the temperature of phase transformation of which is at least 30 degrees centigrade from its solid phase to the liquid phase is deposited. The temperature should then be below the respective temperature of phase transformation. By means of thermal treatment the binding agent and the organic component are expelled, a portion of the powder particles is sintered, and a further portion of the powder particles is connected with the surface of the base foam body in a material-fit manner via sintering bridges.
