    Abstract: The invention relates to a turbine blade with a cover plate shaped onto the pan of the blade. The aim of the invention is to provide a turbine blade of this type that, while having a high level of efficiency, is designed for a particularly reliable and safe operation in a turbine, particularly of a steam turbine. To this end, the invention provides that a protective layer made on an alternative material is applied to the surface of the cover plate facing away from the pan of the blade. The friction behavior with regard to a turbine component, particularly a sealing strip, which is opposite the protective layer, can be specifically influenced whereby enabling favorable emergency running properties to be provided in the event of rubbing.

    Abstract: The present invention provides a variable-throat exhaust turbocharger equipped with a variable-throat mechanism of which connection of constituent members can be achieved with a small number of man-hour and at low cost and which is stable in quality with firm connection of constituent members maintained under severe operating conditions. Among constituent members of the variable throat-area mechanism of the variable-throat exhaust turbocharger for varying the blade angle of a plurality of nozzle vanes supported rotatably by a members in a turbine casing, shaft members to be inserted and fixed in through-holes in a member with through-holes are produced by a method in which wear-resistant material is welded to form cladding of a certain thickness on the upper surface of a steel plate, said material being harder than the steel plate, and then crude shafts for forming drive pins are cut out from the clad plate.

    Abstract: In order to make labyrinth seal lips on the periphery of a metal moving part of a turbomachine, a thick layer of refractory material that adheres to the metal is made prior to assembling the moving part, the refractory material advantageously comprising at least one metal selected for example from Fe, Co, and Ni, together with at least one ceramic selected for example from borides, nitrides, carbides, and refractory oxides. The labyrinth seal lips that are to be made are machined to their final dimensions in the deposited thick layer.
