Abstract

The invention discloses a method for enhancing air poison resistance of Zr2Fe alloy. The method for enhancing the air poison resistance of the Zr2Fe alloy includes steps: S1, simultaneously loading Zr2Fe alloy particles and stainless steel balls into a stainless steel vacuum ball milling tank, and connecting the stainless steel vacuum ball milling tank with a hydrogen storage performance test system; S2, pumping gas out of the stainless steel vacuum ball milling tank, and inflating the stainless steel vacuum ball milling tank with argon gas; S3, performing ball milling on the Zr2Fe alloy particles; S4, inflating the stainless steel vacuum ball milling tank with the argon gas, and passivating the Zr2Fe alloy particles; S5, placing the stainless steel vacuum ball milling tank into a glove box, controlling air inflow of air, and exposing Zr2Fe alloy powder to air; S6, sieving the Zr2Fe alloy powder; S7, preparing silicon dioxide sol; S8, adding the Zr2Fe alloy powder into the silicon dioxide sol and stirring the Zr2Fe alloy powder so as to form cream; S9, heating and drying the cream. The method for enhancing the air poison resistance of the Zr2Fe alloy solves the problem that the Zr2Fe alloy is poor in air poison resisting ability, strengthens use stability of the Zr2Fe alloy, and prolongs use life of the Zr2Fe alloy.

Description

technical field [0001] The present invention relates to a kind of Zr 2 The method for modifying the surface of Fe alloy, specifically related to a kind of enhanced Zr 2 A method for the anti-air poisoning properties of Fe alloys. Background technique [0002] Among the hydrogen storage materials, there is a class of materials called getter materials, which are generally used to obtain ultra-high vacuum in vacuum devices. Zr 2 Fe alloy is a typical getter material, which is usually used in the treatment of tritium-containing atmosphere. Using the metal getter method to capture tritium in an inert atmosphere, compared with the widely used catalytic oxidation-adsorption method, has the advantages of not producing highly toxic tritium water, and the captured tritium is easy to recover. A tritium capture method vigorously developed by the laboratory. The key to this method is the hydrogenation performance of the metal getter. An ideal tritium-capturing metal getter should hav...
