Microstructural and Nanomechanical Characterization of CrCoAlHf/YSZ Multilayer Coatings Deposited by DC/RF Magnetron Sputtering

open access: yesInternational Journal of Ceramic Engineering &Science, Volume 8, Issue 2, March 2026.
A dense Cr/CoAlHf/YSZ multilayer coating was successfully deposited on Inconel 718 by DC/RF magnetron sputtering at 300°C. The coating exhibits nanocrystalline stability, strong interlayer adhesion, enhanced hardness, and excellent chemical integrity, making it suitable for advanced high‐temperature aerospace applications.

Effect of the Fe Content on the Oxide Film Composition and Corrosion Resistance of Inconel 625: An XPS and Cyclic Potentiodynamic Polarisation Study

open access: yesSurface and Interface Analysis, Volume 58, Issue 3, Page 151-163, March 2026.
ABSTRACT The present work focuses on investigating the effect of increasing Inconel 625 Fe content on the oxide film composition and corrosion behaviour through XPS and cyclic potentiodynamic polarisation (CPP) studies. Different proportions of ASTM A182 F22 steel and Inconel 625 were arc‐melted to achieve a range of Fe contents (2–15 wt.%) in the ...
