DEUTERIUM RETENTION IN TiN AND CrN COATED Ti-6Al-4V ALLOY UNDER LOW-ENERGY GLOW DISCHARGE DEUTERIUM PLASMA EXPOSURE
Year: 2024
Type: article
Abstract: The influence of CrN and TiN coatings, deposited by cathodic arc evaporation, on deuterium permeation behavior in Ti-6Al-4V alloy was studied. Depth distribution profiles of deuterium were determined for both coated and uncoated Ti-6Al-4V samples following exposure to low-energy deuterium plasma to a fluence of 1·1023 D/m2 at room temperature. In the uncoated alloy, deuterium was found to redistribute throughout the bulk material, with permeation extending to the back side of the sample with respect to the irradiated surface. In contrast, deuterium permeation was limited to a negligible depth within the CrN and TiN coatings, emonstrating their excellent barrier performance.
