A method of immobilizing a metal catalyst in a porous support includes additively forming a precursor structure on a substrate from a metal catalyst and at least one of a metal oxide or a metal cluster compound; exposing the precursor structure to a vapor of an organic linker; and reacting the at least one of the metal oxide or the metal cluster compound in the precursor structure with the organic linker to form a porous support that immobilizes the metal catalyst.

The bearing system includes a fluid bearing, a shaft with a solid portion, and a bush located around the solid portion and in front of pad or pads of the fluid bearing; the bush includes a hollow portion and a plurality of supporting elements that fix the hollow portion of the bush to the solid portion of the shaft.

The method of protecting a component of a turbomachine from liquid droplets erosion provides covering at least one region of a component surface exposed to a flow of a fluid containing a liquid phase to be processed by the turbomachine with a protective layer. The protective layer consists of a plurality of adjacent sub-layers of different materials having high hardness in the range of 1000-3000 HV and low fracture toughness below 20 MPam. The materials are typically nitrides or carbides of titanium or aluminum or chromium or tungsten. In an embodiment, the covering is carried out by a PVD technique, in particular by Cathodic Arc PVD, or a CVD technique. The method may be applied to any component of turbomachines, but it may be particularly beneficial for parts of centrifugal compressors.

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.
