Title:
METAL ALLOY POWDER FOR 3D PRINTER
Document Type and Number:
WIPO Patent Application WO/2016/021998
Kind Code:
A1
Abstract:
A stainless and titanium alloy powder prepared by a complex atomizing method developed in the present invention has 1/3 or less lower oxygen content in the powder compared with a powder prepared by a conventional water atomizing method and has approximately three times higher oxygen content and 1/4 or less lower nitrogen content in the powder compared with a powder prepared by a gas atomizing method, and thus can be applied to a special use such as a 3D printer and mold injection molding (MIM) requiring a high purity of low oxygen and nitrogen contents. In addition, there is an advantage of enabling the manufacture of a powder having various shapes such as irregular, oval and spherical shapes by varying the ratio of gas and water during complex atomizing, and the manufacturing cost is low compared with a gas atomizing method.
