Project description
Nickel-based alloys in aircraft components
The EU-funded NEMARCO project targets the development of nickel-based aircraft components that will be more resistant to wear and high temperatures and less harmful to human health. Specifically, the project will work on a new generation of sealing rings for butterfly valves that belong to the cabin pressurisation air purging system. These rings are currently manufactured using cobalt-based alloys. New NiCrSiFeB alloy compositions will be explored by adapting centrifugal casting manufacturing parameters or using additive production processes (laser metal deposition). A rigorous lifecycle assessment and a preliminary toxicity study will be carried out to evaluate the environmental and economic impact of the new developments.
Objective
The main objective of NEMARCO is to select the adequate chemical composition(s) and manufacturing process parameters for obtaining sealing rings of nickel self-fluxing alloys that can offer the required performance against high-temperature (HT) wear and overcome the health potential issue regarding wear particles Cobalt alloys (current solution) in cabin air. Two manufacturing routes: Horizontal Centrifugal Casting (CC) and Laser Metal Deposition (LMD), will be studied.
The achievement of this objective is based on a well-structured approach that combines (i) a preliminary selection of NiCrSiFeB commercial compositions that can favour manufacturing processability while improving wear behaviour at HT supported by simulation of phase’s formation, segregation, precipitation and diffusion phenomena to predict microstructure formation, as well as process simulation to evaluate specific conditions for solidification. (ii) Robust manufacturing study of both processing routes supported by advanced data analytics of all process and product related variables, allowing to identify those parameters with the highest influence and thus, support in the definition of the optimal manufacturing conditions. (iii) Extensive tribological studies at high temperature. This will support for the selection of the best composition and manufacturing solution of NiCrSiFeB alloys as replacement of the actual Cobalt alloys to produce aeronautic parts. (iv) A rigorous LCA/LCC and a preliminary toxicity analysis, leading to a deeper knowledge of environmental performance and economic impact of the solution. The project will contribute on a reduction of fuel consumption, healthier cabin air and a reduction of costs for a more competitive EU aircraft industry. The implementation is carried out by a multidisciplinary consortium formed by experts in LMD (LORTEK), CC (AZTERLAN), HT behaviour of materials and wear particles characterization (ECL-LTDS and CIDETEC) and LCA/LCC and toxicity analysis (CTME).
