摘要:
The present invention relates to a process for the laminar bonding of materials using a carrier material and at least one electroconductive and possibly compressed powder coat, or an electroconductive powder which is compressed to form a flat moulded article, whereby the carrier material and the powder coat, or the powder-based moulded article are subjected briefly to a magnetic alternating field in the frequency range of ca. 10 kHz to 120 MHz in order to generate in the powder coat or the powder-based moulded article an induction current of such energy density that the points of contact of the powder particles among themselves and if a carrier material is used, also their points of contact with the carrier material are fused together at a temperature above the sintering temperature.

The invention relates to a ceramic surface in a casting tool, particularly a surface located outside the contouring region, which is exposed to a liquid or free-flowing aluminum material, wherein on at least one ceramic surface a layer is present consisting of an infiltration layer, diffused into the ceramic surface, structural parts in the form of Al2O3 and/or SiO2 and/or ZrO2 and/or TiO2 and a polymer of one or more polymerized phosphates and at least in sections enclosing the primary parts, the structural parts, and the sliding parts. Moreover, the invention relates to a parting agent and a method for preparing a layer of this type.

摘要:
A metallic, ferriferous permanent mold, especially a permanent steel mold, is provided that can be impinged upon with a liquid or flowable aluminum material, a layer for protecting the permanent form and for obtaining an optimum cast result being producible by means of a mold release agent. The invention also relates to a mold release agent for producing said layer and to a method for producing said layer.
摘要:
A concentrate for producing a cooling and release agent for reusable casting dies such as a steel casting die, or a cooling and lubricating agent for machining with an active substance dissolved in water. The concentrate comprises 10 to 50 wt.-% of a protein based on the weight of the concentrate.
摘要:
The invention relates to a metallic functional component, which is subject to thermal or thermal and erosive stress and to which on at least one surface a coating is applied, whereby the coating consists of a binder phase, which consists at least largely of a phosphate, and a material embedded in the binder phase. In addition, the invention relates to a separating agent for preparing a layer of this type, and to a method for applying the coating to a functional component.
摘要:
The invention concerns a metal, iron-containing permanent mold, in particular a permanent mold made of steel, which can be subjected to a liquid or flowable aluminum material, and in which a coating for protecting the permanent mold and for achieving an optimal casting result can be produced using a mold release agent. The invention additionally concerns a mold release agent for producing such a coating, and a method for producing such a coating.
摘要:
A flux for application on and for reduction of oxide layers on a metal surface. The flux includes potassium fluoride, sodium fluoride, remaining moieties of water and gelatin. The can also include a reactant comprising moieties of at least one of the compositions of zirconium fluoride, lithium fluoride, sodium fluoride, potassium cryolite and potassium aluminum fluoride (KaAlF4), moieties of salts on the basis of at least one of the elements zirconium, lithium, potassium, sodium, bismuth boron and titanium and gelatin. The flux can be used in a method to reduce oxide layers on a metal surface by applying the flux onto the metal surface.
