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: 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.
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: 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.
