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. Said 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.
Abstract:
A method for manufacturing a component (1) of a rotating machine comprises the steps of forming a structural inner portion (2) by additive manufacturing from a first material; covering the structural inner portion (2) with a protective outer portion (7) made of a second material; the first material has a melting point higher than a second material.
