Cyclic oxidation of cobalt-chromium-aluminum-yttrium and aluminide coatings on IN-100 and VIA alloys in high velocity gases [PDF]
Embedded-alumina-particle aluminide (EAPA) coated and CoCrAlY coated IN-100 and NASA-TRW-VIA specimens were cyclically oxidation tested in a high velocity (approximately Mach 1) gas flame at 1093 C (2000 F).

Influence of surface treatment on metal dusting resistance of welds
Materials and Corrosion, Volume 75, Issue 3, Page 371-385, March 2024.Fe contaminations enhanced metal dusting pit formation on brushed welds of Ni‐based alloys. The best performance of the welds was achieved by grinding, this is attributed to the deformation of the sub‐surface zone. Additional protection by on‐site slurry aluminization was successfully demonstrated.

A New Al2O3‐Protected EB‐PVD TBC with Superior CMAS Resistance
Advanced Science, Volume 11, Issue 5, February 2, 2024.This study introduces a novel microstructural design for yttria‐stabilized zirconia (YSZ) thermal barrier coatings (TBCs) to resist calcium‐magnesium‐aluminum‐silicate (CMAS) attack. It employs a drip coating method to create a thin nanoporous Al2O3 layer around YSZ columnar grains, enabling fast crystallization of molten CMAS close to the TBC surface.

Ni–W diffusion barrier: Its influence on the oxidation behaviour of a β-(Ni,Pt)Al coated fourth generation nickel-base superalloy [PDF]
, 2009 A Ni–W base diffusion barrier (DB) has been developed to limit interdiffusion between a fourth generation Ni-base superalloy (MCNG) and a Pt-modified nickel aluminide bondcoat. After long term oxidation, the DB layer permits to reduce the Al depletion in
