The invention relates to components which are produced or processed by powder metallurgy, and to processes for producing components of this type. The components produced by powder metallurgy are intended both to have porous regions and to provide fluid-tight properties, and it should also be possible to produce them at correspondingly low cost and suitably flexibly. For this purpose, a component of this type has at least one porous region, which is formed from an intermetallic phase or solid solutions. However, it may also have a corresponding surface coating. Moreover, in a component of this type there is at least one areal fluid-tight region which is formed from a meta or metal alloy of the corresponding intermetallic phase or solid solution.

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.

The invention relates to an apparatus for the separation of particles contained in exhaust gases of internal combustion engines in which the exhaust gas flow is guided through a filter medium in which particles can be absorbed and held back. The invention should improve the separation in a cost effective manner with respect to conventional particle filters. In accordance with the invention, the filter medium () is made from a metal open-pore foam having at least two layers () which each have a thickness, porosity and/or pore size in the flowthrough direction through the filter medium which differ from one another. In one embodiment, the particle filter includes first and second filter medium layers where the first filter medium has a mean pore size larger than a mean pore size of the second filter medium, and the first filter medium has a thickness that increases in a direction of the exhaust gas flow inlet passage of the filter housing.

The invention relates to metal foam bodies having an open-porous structure as well as a method for producing thereof wherein according to the set task such metal foam bodies are to be provided which achieve an increased oxidation resistance and/or an increased corrosion resistance. With the metal foam bodies having an open-porous structure according to the invention, for such metal foam bodies within the webs of the open-porous structure there are channel shaped cavities formed as being determined by the production. At the same time, the webs and cavities will be provided with a metallic protective layer made of a material differing from the metallic starting material of the foam body or the channel shaped cavities will be filled with this material. For this, an adequate metal powder or an alloy component being included in the powder will be used which becomes liquid and forms a liquid phase respectively during thermal treatment below a temperature at which the metal of the base foam body is melting. Due to the capillary action wetting the surfaces of channel shaped cavities within the webs can be achieved such that after cooling down a metallic protective layer is forming or the channel shaped cavities are filled.

The invention relates to open-pored metallic foam bodies as well as a method for manufacturing thereof. These metallic foam bodies are allowed to be advantageously used with ambient environmental conditions causing a high corrosion to many conventional materials, and accordingly reducing the lifetime thereof frequently. According to the set object, the metallic foam bodies should have a low mass simultaneously with a high specific surface, and increased corrosion resistance under chemically aggressive ambient environmental conditions. An open-pored metallic foam body according to the invention is then developed such that it is formed from a nickel-copper alloy having at least 40 percent by weight of nickel and yet a porosity of at least 90%.

The invention relates to a method for producing metal hydroxides or alkaline metal carbonates by anode dissolution of the corresponding metals and precipitation of the hydroxides or alkaline carbonates in an aqueous medium. The anode dissolution of the metal components is carried out in the anode compartment of a three-compartment electrolytic cell. An aqueous auxiliary salt solution is fed to an intermediate compartment that is disposed between the anode compartment and the cathode compartment and that is separated therefrom by a porous membrane. An at least not alkaline metal salt solution is continuously taken from the anode compartment while an alkaline auxiliary salt solution is continuously taken from the cathode compartment. The at least not alkaline metal salt solution and the alkaline auxiliary salt solution are combined outside the electrolytic cell for the purpose of precipitating metal hydroxides or alkaline metal carbonates.

The invention relates to a process for the production of sintered porous bodies, to porous bodies produced correspondingly using the process, and to their use. With the solution according to the invention, sintered bodies which achieve improved properties, such as an increased surface area, deformability of the structures at room temperature or modification of the initial pore volume, are to be produced. To this end, at least one sintering-active powder which forms at least one intermetallic phase or mixed crystals is applied to the surface of a porous basic body. Heat treatment is to be carried out subsequently, in which intermetallic phases or mixed crystals which increase the specific surface area can be formed.

A continuous method of manufacturing a liquid dispersion containing submicron metal or metal compound particles inside a liquid bath. A metal-containing fluid with carrier gas mixture is bubbled through the liquid bath and predetermined conditions in the bath cause the fluid to decompose to form the submicron sized metal or metal compound particles in the liquid.
