Abstract

The invention provides alloyed powder for directly printing metal parts in a 3D (three-dimensional) manner. The alloyed powder is characterized in that nanometer aluminum is adhered to the surface of oxide of iron through a layer of thin tin powder to form iron-base alloy microspheres, the grain size of the microspheres is 2-10 micrometers, the sphericity is greater than 95%, and the alloyed powder comprises the following materials in part by weight: 60-70 parts of iron oxide, 30-40 parts of nanometer aluminum and 0.1-0.5 part of tin powder. The alloyed powder can be directly used for printing the metal parts in the 3D manner. When the alloyed powder is used for directly printing the metal parts in the 3D manner, the iron oxide is gradually reduced through aluminum, structure deformation caused by direct fusion molding of metal, cooling crystallization is uniform, the strength of a molded piece is improved by formed aluminum oxide, the porosity of products is reduced, and the compactness is high. The alloyed powder can be used for directly printing the high-precision metal parts which have complication shapes.

Description

technical field [0001] The invention belongs to the field of 3D printing manufacturing materials, and in particular relates to an alloy powder which can directly use 3D printing to manufacture high-strength and high-density metal parts, and further relates to a preparation method of the alloy powder. Background technique [0002] 3D printing technology is a rapid additive manufacturing technology that generates three-dimensional entities by increasing the accumulation of materials layer by layer. It not only overcomes the loss caused by traditional subtractive manufacturing, but also makes product manufacturing more intelligent, more accurate and more efficient. Especially when it comes to high-end manufacturing of complex shapes, 3D printing technology shows great advantages. 3D printing technology is a high-tech manufacturing technology with industrial revolution significance, which represents a new trend in the development of the world's manufacturing industry. In recent...
