Influence of Thickness of Layers MoNС…/CrNy in Multilayer Coating and Nitriding on Structural and Mechanical Characteristics [PDF]

Журнал нано- та електронної фізики, 2017
In this paper, the processes of formation of multilayer MoNx/CrNy coatings on the nitrided surface of steel 12РҐ18Рќ10Рў are considered. The change in the concentration of nitrogen in the Mo, Cr, and in the depth of the steel is shown.

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

Advanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...
