Title:
TUNGSTEN-DOPED TITANIUM-BASED COMPOSITE POROUS MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/011951
Kind Code:
A1
Abstract:
A tungsten-doped titanium-based composite porous material and a preparation method therefor. Disclosed is use of W in the preparation of the tungsten-doped titanium-based composite porous material. In the preparation of the tungsten-doped titanium-based composite porous material, a small amount of W of a micro-nano size is doped therein, so that the compactness thereof can be improved, and the hardness and abrasion resistance of a matrix can be significantly improved. A plurality of three-dimensional porous structures are distributed in the tungsten-doped titanium-based composite porous material, and the plurality of three-dimensional porous structures form a topological structure or a random structure. The tungsten-doped titanium-based composite porous material comprises Ti, TiC and W. Tungsten metal accounts for not more than 3% of the mass fraction of the tungsten-doped titanium-based composite porous material. The tungsten-doped titanium-based composite porous material is achieved by means of an additive manufacturing method of ink direct writing molding or a method of adding a pore former combined with spark plasma sintering.
