A thrust bearing comprises an electromagnetic stator with a stator surface and a rotor disk with a rotor surface facing the stator surface. The rotor disk comprises a radially inner portion made of a first material directly and exclusively connected to a radially outer portion made of a second material. The first material is a corrosion resistant metal or metal alloy and the second material is a ferromagnetic metal or metal alloy.

Thrust bearing, a turbomachine, and a method of making a bearing rotor disk for an electromagnetic thrust bearing in a turbomachine

System, computer software and method for determining a susceptibility to reheat cracking of a sample of material, which includes a welded area. The method includes measuring a length of the sample, applying a first stress to the sample to achieve a predetermined elongation of the sample, exposing the elongated sample to a predefined heat treatment, applying a second stress to the sample until the sample breaks at least into two different pieces, and determining the susceptibility of the broken sample to reheat cracking.

Method for determining reheat cracking susceptibility

Ultrasound inspection methods for noisy materials and related probes are disclosed to inspect a defect in a cast material that use polycarbonate delay layers having a first surface configured to be disposed on a surface of the cast material; and an acoustic crystal element disposed on a second surface of the polycarbonate delay layer.

A mounting system for a liner within a combination chamber of a gas turbine, where the liner is secured at one upstream end to a burner and at an opposite downstream end to a transition duct, the mounting system comprising:

Mounting system for a flame pipe or liner

Vapor turbine operating with geothermal vapors containing corrosive agents such as chlorides and/or sulfides in particular. The turbine comprises a series of sealing laminas made of a nickel alloy containing a quantity of nickel ranging from 54% to 58% by weight to avoid the washing of the geothermal vapors, maintaining a high useful life of the series of sealing laminas and vapor turbine.

Vapour turbine

Vapour turbine operating with geothermal vapours containing corrosive agents or aggressive substances such as chlorides and/or sulfides in particular. The turbine comprises a series of stator blades and a series of rotor blades, each stator blade of the series of stator blades comprises a surfacing consisting of a nickel alloy containing a quantity of nickel ranging from 54% to 58% by weight to avoid the washing of the geothermal vapours, at the same time maintaining a high useful life of the series of stator blades and vapour turbine.
