Embodiment Construction

[0023] Now in conjunction with the accompanying drawings, the preferred embodiments of the present invention will be described in detail.

[0024] Such as figure 1 As shown, the present invention provides a method for laser additive manufacturing of porous aluminum alloys. The size of the formed pores is controlled by precisely controlling the interval of the linear trajectory, and then the porosity of the aluminum alloy is controlled. In this way, a dense structure and high hardness can be obtained. , Aluminum alloy with high metal performance.

[0025] The method includes the following steps:

[0026] S1: uniformly paving the first layer of alloy powder on the substrate 10;

[0027] S2: The laser 20 focuses on the first layer of alloy powder for scanning to form a number of first linear trajectories 1, while scanning, the gas blowing device 30 blows protective gas to the melting place of the alloy powder; wherein, several first linear trajectories 1 are parallel Interval ...

Abstract

The invention relates to a manufacturing method of a laser additive for a porous aluminum alloy. The method comprises the following steps that first layer alloy powder is laid on a base plate uniformly; a laser device focuses the first layer alloy powder to carry out scanning, and a plurality of first linear tracks are formed; the first linear tracks are arranged at intervals and in parallel; second layer alloy powder is laid on the first layer alloy powder uniformly; the laser device focuses the second layer alloy powder to carry out scanning, and a plurality of second linear tracks are formed; the second linear tracks are arranged at intervals and in parallel and are perpendicular to the first linear tracks to form a plurality of holes; according to the principle that (N+1) linear tracksof (N+1) layer alloy powder are perpendicular to N linear tracks of the Nth alloy powder, layer-by-layer stacking is achieved, and laser additive manufacturing of the porous aluminum alloy is achieved. The size of the formed holes is controlled by accurately controlling the intervals of the linear tracks, then the porosity of the aluminum alloy is controlled, and in this way, and the aluminum alloy with compact organization structure, large hardness and high metal performance can be obtained.

Description

technical field [0001] The invention relates to the technical field of laser additive manufacturing, in particular to a laser additive manufacturing method for a porous aluminum alloy. Background technique [0002] Laser additive manufacturing technology is a typical rapid prototyping technology, which mainly uses high-energy laser beams to melt metal powder, accumulate layer by layer, and directly form high-performance complex metal parts. Porous metals generally have the characteristics of light weight, large specific surface area, high porosity and controllability, etc. Porous metal materials generally have excellent properties of structural materials and functional materials, so their application range is very wide. [0003] At present, most porous materials are produced by foaming technology, such as aluminum foam. Foamed metal is to add tackifier and foaming agent to the molten metal, and after stirring, use methods such as vulcanization casting to produce foamed alum...
