Abstract: A corona shield for an electric machine, has a varnish that contains a first polymer resin, first electrically conductive particles that are dispersed in the first polymer resin, and microcapsules which are dispersed in the first polymer resin and include a second polymer resin in their interior.

Abstract: A turbomachine includes an inner housing which radially defines the flow channel of the turbomachine. A thermal barrier coating is arranged about the inner housing. The thermal barrier coating of the inner housing is made of microporous plastic coating which can be added to hollow spheres made of different materials and have different sizes. A method for applying a thermal barrier coating to the inner casing of a turbomachine includes preparing a material having a base material which has a microporous plastic; coating the outside of the wall of the inner casing by applying the base material to the inner casing; and curing the applied material, thus forming the thermal barrier coating.

Abstract: A mounting device for mounting a guide blade to be mounted in a blade groove of a turbine, where the mounting unit has a clamping unit and a pressing unit. Here, the clamping unit is designed to produce in the blade groove a non-positive connection in a circumferential direction. The pressing unit is arranged behind the clamping unit in the circumferential direction and the pressing unit is supported against the clamping unit in the circumferential direction. The pressing unit is designed to apply a pressing force by means of a pressing piston in an opposite direction to the circumferential direction in a mounting direction and to transmit said force to the guide blade to be mounted.

Abstract: An arrangement for securing turbine blades in a groove of an inner housing of a steam turbine is provided. A caulking piece which is made of bi-metal is used between the base of the turbine guide blade and the groove. The component is designed as a casing, in particular as an inner casing of a steam turbine.
