  • Publication number: 20250051926
    Abstract: A system for performing electroless nickel plating on a portion of a metallic piece comprises a chamber fixedly coupled to the metallic piece during operation of the system so that the portion of the metallic piece and the chamber define a closed volume. The chamber has an inlet to supply at least a plating fluid into the volume and an outlet to discharge the plating fluid from the volume, so that the portion of the metallic piece is exposed to the plating fluid and is plated.

  • Patent number: 11998900
    Abstract: 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.

  • Publication number: 20220163047
    Abstract: A shrouded impeller for centrifugal compressors, and methods for manufacturing shrouded impellers for centrifugal compressors are provided. In one embodiment, the method includes manufacturing an impeller base, then depositing by cold spraying at least one layer of metallic material on the surface of the frontal part of the impeller corresponding to the shroud of the impeller and machining the impeller to complete and finish the structure thereof. The at least one layer deposited by cold spraying may include grooves adapted to optimize the dynamic behavior of the impeller by modifying and tuning the local natural frequencies.

  • Patent number: 10526903
    Abstract: 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 MPam1/2. 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.

  • Patent number: 9926976
    Abstract: 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.

  • Publication number: 20170241429
    Abstract: A method of manufacturing a component of a turbomachine by powder metal hot isostatic pressing is disclosed, which uses a container defining outside surfaces of the component. A metal insert is located inside the container before filling the container with metal powder, and the insert is left in the component after the end of its manufacturing. In an embodiment, a metal core is located inside the container before filling the container with metal powder, and the core is removed from the component before the end of its manufacturing. In this way, net shape surfaces may be obtained without manufacturing trials.

  • Publication number: 20150252676
    Abstract: Apparatus and method for decreasing the corrosion susceptibility and/or the liquid droplet erosion susceptibility of one or more turbine blades associated with a steam turbine. One or more of the turbine blades are constructed of an Austenitic Nitrogen strengthened stainless steel; such Austenitic stainless steel has a weight percentage of manganese bigger than ten and preferably a weight percentage of nickel smaller than five; advantageously, such Austenitic stainless steel is strengthened with nitrogen. The blades constructed of such Austenitic stainless steel are configured in the later stages of the steam turbine.
