Atomized Aluminum Powder

Atomized aluminum powder is currently a common powder in the metal additive manufacturing sector. However, there are other critical factors and safety concerns that must be addressed. This article will offer you with crucial information about the use of atomized aluminum powder. You will also learn about the various uses for which atomized aluminum powder is acceptable. We'll also go over the distinctions between spherical and spheroidal morphology. Furthermore, we will investigate the optimization of powder qualities, which will aid in the development of metal additive manufacturing.

Spheroidal vs spherical particle morphology

Several investigations on aluminum-alumina composites have been undertaken. These investigations concentrated on the particle shape of aluminum powder. The investigation employed a ThermoScientific X-2 mass spectrometer outfitted with an inductively coupled plasma cannon. Table 2 displays the results.

Spherical particles were present in the initial aluminum powder. After oxidation in water, the form remained unchanged. On the particles, an oxidation product layer formed. The hydroxide layer had bigger crystals and appeared denser. The agglomerates were much larger than the average Al particle diameter. The agglomerates, on the other hand, had little effect on the particle size distribution.

The powder was oxidized in water at 120-200 degrees Celsius. The oxidation process took roughly 140 minutes. The particles had an average diameter of 41-42 um. The alumina content of the powdery composites ranged from 20 to 80 weight percent at 120 degrees Celsius and increased to 20.0 weight percent at 200 degrees Celsius. A greater alumina percentage was associated with a longer reaction time.

SEM was also used to examine the alumina content. The alumina concentration of aluminum-alumina powdery composites was shown to be related to the relative intensity of g-Al2O3 peaks.

Aluminum-alumina composite particle size distribution curves were similar to those of the initial aluminum powders. However, the powdery composites oxidized further following calcination. This was most likely owing to the oxide layer's lower density when compared to aluminum.

Inert gas atomisation also created spheroidal particles. The majority of these powders are made with argon, however helium is also employed. Despite their spherical shape, these particles lack the reactive characteristics of flake metal powders. As a result, they are suitable for the preparation of core-shell composites.

In addition, the particle morphology of the aluminum-alumina composites was also studied. The results indicate that the spheroidal particles are suitable for metal AM. However, they did not reproduce the scattering matrix elements of feldspar. A superspheroidal model had better reproducibility of the phase function and -P12/P11 element. The small-scale roughness of the superspheroidal model affects the polarization of the model particles.
