Definitions
- the present invention relates to a method for preparing a metal powder intended for an additive manufacturing process, of the scanning type of a powder bed by laser beam in the near infrared.
- the aim of the present invention is to provide a new method for preparing a metal powder, in particular for shaping metals that are difficult to "lasable” in additive manufacturing, overcoming the above drawbacks.
- - Functionalization comprises precipitation of at least one second material, in the form of a compound which acts as a flux (chemical stripper) during the lasering operation.
- flux is meant an antioxidant chemical compound that removes oxides and ensures optimum welding of the grains under the laser beam.
- the latter can for example be chosen from halogenated compounds, borax and organic acids.
- the flow function of the second material therefore implies very specific structural characteristics.
- FIGS. 1 and 2 show the steps in producing a 3D part (5), by implementing an SLM additive manufacturing process.
- a thin layer of powder (1) is spread by a roller (6) from a plate (7) to a piston (8), to form a bed of powder (2).
- the piston (7) is at its highest point.
- FIGS. 5 and 6 illustrate tests carried out on a copper powder (1) functionalized with nickel.
- the grains (4) comprise a continuous thin layer (20) of nickel on the surface of the copper particles (10).
- Nickel has low optical reflectivity, and its presence on the surface of the grains (4) considerably improves the laser / material interaction compared to a pure copper powder.
- the functionalization is carried out by germination and then growth of a surface layer (20) on a support particle (10).
- Sub-mode M21 shows partial functionalization, with a discontinuous layer (20).
- the M22 submode shows continuous functionalization, with strong variations in thickness of the continuous layer (20).
- the M23 submode shows continuous functionalization, with small variations in thickness of the continuous layer (20).
- the roughness is controlled.
- the particles (10) of the first material undergo a functionalization treatment, then the functionalized particles (10 + 20) undergo a physical and / or chemical attack.
- the powder (1) can be shaped differently from Figures 4 to 10 without departing from the scope of the invention, which is defined by the claims.
- the technical characteristics of the different variants mentioned in the description may be, in whole or for some of them, combined with each other.
- the powder (1) can be adapted to the targeted applications.
