The invention belongs to the field of palladium alloy membranes and preparation thereof, and discloses a palladium-copper-zinc alloy membrane for hydrogen separation and a preparation method of the palladium-copper-zinc alloy membrane. According to the method, the complete, compact, continuous and uniform palladium metal separation layer is prepared on the surface of the cheap macroporous carrier in the modes of polyacrylonitrile surface treatment of the macroporous carrier, agile activation, chemical plating of the palladium-copper-zinc alloy membrane and aftertreatment of the palladium-copper-zinc alloy membrane. Compared with a palladium alloy membrane prepared by a conventional method, the palladium-copper-zinc alloy membrane for separating hydrogen is thinner, the gas flux and selectivity of the palladium-copper-zinc alloy membrane are high, the comprehensive targets of improving the membrane performance and reducing the membrane cost can be achieved, and the palladium-copper-zinc ...

The invention discloses iron-based alloy powder for plasma cladding and a preparation method and application of the iron-based alloy powder, and belongs to the technical field of alloy materials. The iron-based alloy powder for plasma cladding provided by the invention comprises the following components in percentage by mass: 25-40% of Mo, 1-5% of Ni, 1-5% of Cr, 1-4% of B, 0-3% of CeO2 and the balance of Fe. According to the iron-based alloy powder for plasma cladding provided by the invention, the components with proper mass percent are selected, and the contents of other elements are controlled within a certain range, so that the iron-based alloy powder can be applied to preparation of a subsequent cladding layer in a plasma cladding manner; and the obtained cladding layer has excellent hardness, obdurability and wear resistance, and is well combined with a matrix metallurgical material. And the provided preparation method of the iron-based alloy powder for plasma cladding and the cladding ...
