Abstract

It is an object of the present invention to provide a method of manufacturing titanium hydride powder that is capable of manufacturing titanium hydride by using titanium scrap generated during machining as a raw material. Further, according to the method of manufacturing titanium hydride powder, since the titanium scrap is hydrogenated and changed into powder at the same time for a short time, it is possible to reduce the number of processes and manufacturing cost and to improve productivity. In order to achieve the object, according to an embodiment of the present invention, a method of manufacturing titanium hydride powder includes charging titanium scrap into a reaction container, removing air in the reaction container and supplying hydrogen gas to the reaction container, and performing ball milling.

Description

technical field [0001] The present invention relates to a method for producing titanium hydride powder. More specifically, the present invention relates to a method for producing titanium hydride powder, using titanium or titanium alloy waste generated during processing as a raw material, and performing ball milling to hydrogenate titanium or titanium alloy waste while simultaneously converting these titanium Or titanium alloy waste into powder. Therefore, it is possible to remarkably reduce manufacturing costs and improve productivity. Background technique [0002] Titanium is a light yet strong material. And titanium has been widely used as aircraft body materials, wear-resistant materials, high-strength alloy materials, tool materials, functional ceramic materials, heat-resistant materials, surface coating materials and catalyst materials. As a result, the amount of scrap generated after titanium machining, and specifically, the amount of turning chips generated during...
