Advanced Engineering Materials, EarlyView.Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

ELECTRICAL PROTECTION OF MICROGRIDS
EMERG - Energy. Environment. Efficiency. Resources. GlobalizationThe present work originates from the necessity of evaluating the electrical supply scheme of a bus charging station. Based on this framework, a microgrid model interconnected with the public network was developed, within which the calculations and dimensioning of short-circuit currents and transformer operating voltages were carried out.

Feasibility of Nitrogen as a Carrier Gas for Inconel Cold Spray in Hydropower Application
Advanced Engineering Materials, EarlyView.N2, despite being nearly two orders of magnitude cheaper than He, is a feasible carrier gas for cold spray Inconel coatings in hydropower repair applications when higher gas temperature and pressure are used. Reducing powder size significantly improved cavitation resistance, while the addition of fine chromium carbide particles further enhanced erosion
