“…Aluminum matrix composites (AMCs) have been adopted to increase wear resistance and hardness. Coating metal powders can produce AMCs with reinforcement particles such as Al 2 O 3 and SiC [83][84][85]; hexaborides such as CeB 6 and LaB 6 are used as grain refiners in aluminum alloys both in powder metallurgy [86] and in casting and wrought metallurgy [87,88].…”

In the last years, functionalized powders are becoming of increasing interest in additive manufacturing (particularly in laser powder bed fusion processing, L-PBF), due to their improved flowability and enhanced processability, particularly in terms of laser absorbance. Functionalized powders may also provide higher final mechanical or physical properties in the manufactured parts, like an increased hardness, a higher tensile strength, and density levels close to theoretical. Coatings represent a possible interesting approach for powders’ functionalizing. Different coating methods have been studied in the past years, either mechanical or non-mechanical. This work aims to present an overview of the currently obtained coated powders, analyzing in detail the processes adopted for their production, the processability of the coated systems, and the mechanical and physical properties of the final parts obtained by using L-PBF for the powders processing.

The Al-B-Ca alloy ingot is prepared by arc-melting with Al-3B and Al-10Ca master alloys and the in situ CaB 6 -Al 4 Ca/Al composite inoculant ribbon is carried out through melt-spinning of Al-B-Ca alloy ingot. Afterwards, Al-B-Ca alloy ingot and CaB 6 -Al 4 Ca/Al inoculant ribbon are added into the melt of Al-10Si-0.3Mg alloy as inoculants to verify their refining and modifying effects, respectively. It is found whether in Al-B-Ca alloy ingot or CaB 6 -Al 4 Ca/Al inoculant ribbon, CaB 6 particles have a cubic shape. Compared to the micron-sized CaB 6 particles in the ingot, the size of CaB 6 particles in the ribbon can reach to subnanoscale and nanoscale level. With the same amount of addition, CaB 6 -Al 4 Ca/Al inoculant ribbon has a better refining effect than Al-B-Ca alloy ingot, but both of them have similar modifying effects for eutectic silicon. In addition, the mechanical properties of Al-10Si-0.3Mg alloy inoculated by the ribbon are superior to that of Al-10Si-0.3Mg alloy inoculated by the ingot. The mismatch between CaB 6 and Al is particularly small and certain orientation relationships are existed between them. Therefore, the impact of CaB 6 particle size on refining effect of the inoculants, the heterogeneous nucleation mechanism of CaB 6 , and the strengthening mechanism of Al-10Si-0.3Mg alloy after inoculation are investigated.
