Study of Deposition Efficiency of Alsi10mg Powder Deposit on Dc04 and 2017a

Amela Kusuran

In current study, the formation of static thick deposits during cold spraying of AlSi10Mg aluminum alloy powder on 2017A and DC04 substrates is considered. It is shown that bigger particles are mostly making the deposit and are more attracted to the top of each deposit The speed of construction of the deposit is determined showing a maximum at the beginning of spraying and a quick decrease after a few seconds due to the decrease of the angle of impact between surface and particles. In consequence, deposition efficiency is also maximal at the beginning and is strongly decreased as the deposit grows.

Additive Manufacturing of Multi-Material Assembly

Thermal spray (2023)

Amela Kusuran Geoffrey Darut Ludovic Vitu Marie-Pierre Planche D. Mercs

Abstract The objective of this work is to assemble an aluminum alloy to a steel to reduce the final mass of this assembly. Doing that, cold spray is considered as an efficient solution. Surfaces are previously prepared with a texturing laser to improve the adhesion of the coating on the substrate. Deposits are slightly rough (Ra < 10 μm), porosity is less than 1% and adhesion is higher than 80 MPa for textured surfaces. These high values are also due to the high filling rates in holes (100% for steel and 65% for aluminum alloy). Shear values obtained through the combination of laser texturing and cold spray for multi-material assembly are of 90 MPa (a heat treatment of 3h at 300°C applied on the joining point improves mechanical strength and increases it by three). By analogy with linear joining methods such as Laser Welding (190 MPa), the values obtained in uniaxial tension by this assembly method are significantly lower (around 50 MPa). It can be explained by the nature of the joining bead, which is made of aluminum alloy.
