Title:
ALUMINUM-BASED PHOSPHORESCENT COMPOSITE MATERIAL AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2012/063408
Kind Code:
A1
Abstract:
The present invention provides an aluminum-based phosphorescent composite material that exhibits phosphorescence, is inexpensive and lightweight, and has high mechanical strength at room temperature and at high temperatures, and a method for producing same. An aluminum powder and a phosphorescent material powder are introduced into a mixing device and are subjected to mechanical grinding. In this way, mechanical energy is applied to the aluminum powder, and thus, the aluminum powder is subjected to stress and work hardened, increasing the mechanical strength and the hardness thereof. With this process, it is possible to obtain a powder mixture of the aluminum powder with increased mechanical strength and hardness and the phosphorescent material powder. The powder mixture is introduced into a mold, sintered by spark plasma sintering, and molded into a desired shape.
