Searching for tritium permeation barrier (TPB) with high tritium permeation resistance is one of the key tasks in the development of nuclear fusion reactor systems. In this study, we propose a novel N doped multi-component metal oxide coating (MCMO), where nitrogen doping can significantly improve the deuterium permeation resistance of the coating. Such a system can also be used to simulate the influence of produced N by the transmutation reaction of neutrons with oxygen in oxide TPB coating. Grazing incidence X-ray diffraction (GIXRD) analysis revealed that the phase structure of the coating remained amorphous after N doping. Through deuterium permeation testing, it was found that the coating has a very high PRF value of 12000 at 500 °C, which has 2.2 times enhancement in PRF compared to that of the pristine (TiVAlCrZr)O coating. Notably, the permeation process does not change the coating microstructure. Ab initio calculations reveal that the N species acts as cages to mitigate the hydrogen isotope permeation. Therefore, nitrogen doping is expected to be a new strategy to further enhance the performance of metal oxide tritium permeation barrier.
