Abstract: An elastocaloric heat pump requiring little installation space wherein the elastocaloric heat pump includes an elastocaloric element, a first coolant duct and a second coolant duct and at least one drive device, wherein the elastocaloric element is connected to a carriage on the end sides in each case, the carriages are arranged displaceably on two guide mechanisms which are not parallel to each other, and the drive device cyclically displaces the carriages along the guide mechanism so the elastocaloric element is displaced cyclically and cyclically expanded between the first coolant duct and the second coolant duct.

Abstract: In order to provide a cascade heat pump with which a large temperature lift can be provided with high efficiency, a cascade heat pump comprising n stages where n?2 is proposed. Each of the n stages has a heat pump with a coolant inlet, a first coolant outlet, and a second coolant outlet. Each heat pump has a hot side and a cold side and a flow divider to divide a coolant flow entering the coolant inlet between the hot side and the cold side. The first coolant outlet of the heat pump of each stage i, where i=1 . . . n?1, is connected to the coolant inlet of the heat pump of a subsequent stage i+1. The second coolant outlet of the heat pump of at least one subsequent stage i+1 is connected by a recirculation line to the coolant inlet of the heat pump of a preceding stage.

Abstract: In a method for coating a substrate, and a coated object, in a first step, in an external current-less or electrolytic manner, nickel and/or cobalt and/or platinum are deposited on a substrate in a deposition bath. In the deposition bath, particles are additionally suspended which contain at least one metal selected from Mg, Al, Ti, Zn and no Cr, the particles becoming occluded in the coating. In a second step, the actual protective layer is produced by heat treatment. The coating of component parts may be used for aircraft turbines or gas turbines or for garbage incineration systems having temperature-resistant protective layers against high temperature corrosion.

Abstract: A method for selectively removing a first layer from an engine component including the first layer, a base material and a second layer forming a bond connecting the first layer to the base material is provided. The method includes applying a salt melt to at least one section of the engine component including at least one portion of the second layer so the bond formed by the second layer between the base material and the first layer is at least weakened.

Abstract: A process for electrochemical stripping of components is disclosed. An operating point of the electrochemical stripping is determined under actual process conditions prior to the actual electrochemical stripping and is determined anew continuously, i.e., monitored and optionally adjusted during the electrochemical stripping.
