Abstract: A method for removing the coating from a gas turbine component, namely for the complete or partial removal of a multilayer wear protection coating from the surface of the gas turbine component, the wear protection coating having at least one relatively hard ceramic layer and at least one relatively soft metallic layer, wherein, in order to remove the multilayer wear protection coating, the gas turbine component is alternately positioned in two different chemical baths, a first bath being used exclusively for the removal of each relatively hard ceramic layer, and a second bath being used exclusively for the removal of each relatively soft metallic layer of the wear protection coating.

Abstract: A facility for the selective separation of a stream of mixed bulk materials made up of objects of different densities and possibly different sizes comprising a sorting device having at least one conveyor belt on which the stream of mixed bulk materials to be selected is conveyed; and at least one nozzle by means of which compressed air can be blown transversely to the conveying direction and against the stream of mixed bulk materials lying on the conveyor belt, including at least one separating element and at least two collection containers, one of which is placed laterally approximately opposite the nozzle and the other of which is placed in the end region of the conveyor belt.
