After adding Y, Cu, Ru or In to Pd to further prepare the palladium alloy membrane, its hydrogen permeability and strength properties will change. The hydrogen permeability and physical properties of palladium-based alloy films, as well as the influence of temperature and gas composition on properties are introduced. The performance characteristics and application fields of PdAg, PdCu, PdY, PdRu and PdInRu are described. |
