In-situ formation of particle reinforced Aluminium matrix composites by laser powder bed fusion of Fe2O3/AlSi12 powder mixture using laser melting/remelting strategy

Journal of Materials Processing Technology, 2022
In-situ preparation of particle reinforced Al matrix composites (PRAMCs) by laser powder bed fusion (LPBF) is a promising strategy to strengthen Al-based alloys. The laser-driven thermite reaction can be a practical mechanism to in-situ synthesise PRAMCs.

Mechanical pretreatment before electroplating of aluminium alloy AlSi12

Surface and Coatings Technology, 2018
Abstract Electroplating is a coating process used to increase the durability of workpieces or to change their appearance. To form a high adhesive bonding between the coating and the workpiece, its surface has to meet certain requirements achieved by a comprehensive pretreatment.

The Production and Subsequent Selective Laser Melting of AlSi12 Powder

Solid State Phenomena, 2017
The paper studies the atomization of Al-based alloy AlSi12 in gas jet. Air was used as a spraying gas. The size and shape of powder particles were studied by using scanning electron microscopy and optical granulomorphometer. The obtained powder was used in selective laser melting.

Thermal processing and thermal analysis of AlSi12–SiC hybrid composites sintered

Journal of Thermal Analysis and Calorimetry, 2019
Metal powders are used in industry for a diversity of products and applications. Metal matrix composites are materials developed through advanced methods with increased characteristics that surpass those of conventional materials. In recent years, the aluminum alloy matrix composites (AlSiX/graphite, AlSiMg/SiC, Al/SiC) are considered better substitute

Copper Plating on SiCp by Cooling Crystallization and Its Effects on the Spreading and Infiltration of AlSi12 Alloy Melt

Advanced Engineering Materials, 2023
A new cooling crystallization method is applied to plate copper on SiCp. Cu(NO3)2·3H2O is crystallized on SiCp by decreasing the solution temperature, and is heat‐treated to obtain CuO coating which is finally reduced to copper coating.
