Additive Manufacturing Nickel Base Alloy Characterization in Hydrogen Environment for Gas Turbine Applications

Energy transition requires, among other things, deeper knowledge of materialsMaterials behavior in hydrogen. Additive manufacturingAdditive manufacturing (AM) is a technologyTechnology that allows designers to accelerate the hydrogen transition happening in turbomachinery, but further characterizationCharacterization of the additiveAdditive alloys in this environment is still necessary. This paper collects results obtained by Baker Hughes testing metallic materialsMaterials in hydrogen environment, namely a nickelNickel base alloy processed by additive manufacturingAdditive manufacturing (AM). The alloy is deployed for gas turbine fuel burners which are components of paramount importance for achieving optimal combustion and low emissions. The hydrogen embrittlementHydrogen embrittlement susceptibility of the materialMaterials is analyzed by a testing method which envelops turbomachinery operative conditions.
