  • Process for making a component of a turbomachine, a component obtainable thereby and turbomachine comprising the same
    Patent number: 11780010
    Abstract: Turbomachines, as well as their components, are disclosed being in the field of production and treatment of oil and gas containing e.g. hydrocarbon plus hydrogen sulfide, carbon dioxide, with or without other contaminants. The components are made of a high corrosion high temperature resistant alloy, capable of resisting to corrosion and/or stress at high temperature better than state of art martensitic stainless steels and behaving similarly to premium nickel base superalloys, and at the same time showing a very improved hardness value.
    Type: Grant
    Filed: May 25, 2017
    Date of Patent: October 10, 2023
    Assignee: Nuovo Pignone Technologie SRL
    Inventors: Filippo Cappuccini, Massimo Giannozzi, Massimiliano Buccioni, Domenico Di Pietro
