Abstract

The invention discloses an element with hydrogen absorption and desorption and foreign gas adsorption functions and a preparation method thereof. According to the element, an alloy of titanium, zirconium and molybdenum is used as a hydrogen absorption and desorption alloy, an alloy of titanium, zirconium, manganese and iron is used as an impurity gas adsorption alloy, and the element is formed bysintering a blank formed by a hydrogen absorption and desorption alloy material and an impurity gas adsorption alloy material. The element is used for hydrogen absorption and desorption impurity gas removal of the pseudo spark switch. The preparation method comprises the following steps: (1) smelting zirconium and titanium to obtain a hydrogen absorption and desorption alloy cast ingot; (2) smelting titanium, zirconium, manganese and iron to obtain an impurity gas adsorption alloy cast ingot; (3) crushing and pulverizing the two alloy ingots, proportioning the two alloy powder, high-purity molybdenum powder and a lubricant according to a target component ratio, carrying out ball milling and screening on the mixed powder, and grinding the alloy particles into powder by adopting an airflow mill; (4) preparing the powder into an element blank in an argon protective atmosphere; (5) putting the element blank into protective gas or a vacuum environment for sintering to prepare the element.

Description

technical field [0001] The invention relates to a component with functions of hydrogen absorption and desorption and impurity gas adsorption and a preparation method thereof. The component can be used for hydrogen absorption and desorption of a pseudo-spark switch to remove impurity gas. Background technique [0002] The pseudo-spark switch is the most important development in the field of pulsed power technology since the 1980s. Pseudo-spark switches can be used to generate high-repetition frequency steep-wave pulse currents, which are characterized by small size, fast start-up, large peak current, steep discharge current rise, small discharge jitter time, small electrode ablation, and long life. The quick return of strength makes it ideal for quick closures. [0003] The pseudo-spark switch consists of a hollow cathode and a flat anode. The two poles are separated by an insulating material. The gap is filled with hydrogen. The hydrogen pressure is adjusted to about 95% of...
