Abstract

The invention discloses strengthened type nanometer WC / AlSi10Mg composite powder and an additive manufacturing technology and belongs to the technical field of additive manufacturing. The additive manufacturing technology comprises the following steps of adding 0.1 percent of nanometer WC in AlSi10Mg powder, performing mixing on the two powders for 20min with a GH-17 type three-dimensional motionefficient mixer, and then performing drying for 10h with a vacuum drying tank to obtain the strengthened type nanometer WC / AlSi10Mg composite powder. The composite powder has the characteristics of better mobility, high sphericity degree, high printing stability and the like; and by melting and solidifying the composite powder with laser, the plasticity of AlSi10Mg alloy is improved while the strength of the AlSi10Mg is improved.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, and more specifically relates to enhanced nano-WC / AlSi10Mg composite material powder and an additive manufacturing process. Background technique [0002] AlSi10Mg alloy has the advantages of low density, good corrosion resistance and high specific strength, which make it widely used in aerospace, automobile and heat exchange equipment. AlSi10Mg alloy parts produced by SLM have close to full density and have excellent mechanical properties compared with materials produced by conventional casting processes. However, modern industry is increasingly looking for lightweight materials with high strength and stiffness, and traditional processing materials are far from suitable for current and future SLM industrial applications. Therefore, there is a need to find a novel composite material for industrial applications. Particle-reinforced aluminum matrix composites can be widely used in v...
