Abstract: 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.

Abstract: 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.

Abstract: 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.
