Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Kinetic Characterization and NOx Reduction Mechanism of Mixed Ammonia-Hydrogen Combustion in Cyclone Combustor

发电技术
ObjectiveAmmonia plays a key role in achieving the “dual carbon” goal, but ammonia has a low combustion rate and high NOx emission. In order to improve the combustion rate, a method of ammonia-hydrogen blending combustion was proposed.MethodsThe combined

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

Advanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

The use of hydrogen as a fuel in road transport on the Polish path to climate neutrality - a literature review

Environmental Protection and Natural Resources, 2023
Hydrogen is expected to be one of the most important fuels meeting stringent emission standards shortly. Using hydrogen as a fuel in an internal combustion engine (ICE) is an alternative application to replace hydrocarbon fuels that, when burned, produce
