Hydrogen Resistance Coatings via Hydrogen Diffusivity Minimization Based on Computationally Engineering Intrinsic and Extrinsic Defect Structure

Hydrogen-resistant coatings and associated systems and methods are generally described. In some aspects, a hydrogen-resistant coating comprises a doped tin oxide comprising one or more dopants. The doped tin oxide may, in some cases, exhibit low hydrogen solubility and low hydrogen diffusivity and may therefore reduce and/or prevent permeation of hydrogen in an underlying substrate. In some embodiments, the one or more dopants comprise one or more transition metals (e.g., tungsten, molybdenum, niobium).
