Preparation process of hydrogen-storage crack-free zirconium-titanium-copper alloy electrode wafer

Abstract

The invention discloses a preparation process of a hydrogen-storage crack-free zirconium-titanium-copper alloy electrode wafer. The preparation process comprises the steps of 1, adopting metallic titanium, metallic zirconium and metallic copper as raw materials, and preparing a zirconium-titanium-copper alloy through a water-cooling copper crucible electromagnetic induction vacuum suspension smelting method according to the mixing ratio of the raw materials; 2, machining a zirconium-titanium-copper alloy ingot obtained in step 1 into a sample in a certain shape and of a certain size, and conducting a series of treatment on the surface of the zirconium-titanium-copper alloy ingot; and 3, conducting a hydrogen absorption reaction on the zirconium-titanium-copper alloy sample obtained in step2, so that a finished product is obtained. The preparation process starts with the more essential materials and focuses on developing an alloy material excellent in performance; and the alloy material can reduce the bulking and hydrogen embrittlement effects generated due to hydrogenation in the hydrogen absorption process through the pinning effect of certain microelements.

Description

technical field [0001] The invention relates to the technical field of preparation of metal hydrogen storage materials and hydrogen storage electrodes, in particular to a preparation process of a source sheet of a zirconium-titanium-copper alloy electrode for hydrogen storage without cracks. Background technique [0002] Metal hydrides (hydrogen including all three isotopes, protium, deuterium, and tritium) are often used in discharge electrodes, such as vacuum arc ion source electrodes. During the discharge process between the electrodes, abundant hydrogen ions and metal ions of various valence states will be produced. The traditional metal hydride electrode is prepared by the method of bulk hydrogen absorption. In this method, a metal or alloy electrode of a certain size is processed first, and then hydrogen is absorbed at high temperature, and the metal hydride electrode of the required size is obtained after the body expands. Due to volume expansion and hydrogen embritt...
