“…5). In fact, such a backward growth of cellular structure can be found in the results of the study of Ignat 7) and Miyamoto 11) on laser cladding of Al on Mg and Cu on Al respectively, but unfortunately the phenomenon was not discussed. An XRD analysis was conducted to determine the various phases present at the interface region between the substrate and the cellular layer.…”

“…Similar work was performed by Majumdar,5,6) where systematic studies were conducted on the laser surface treatment of Mg-based alloys, with different alloying elements, for improving the corrosion resistance of the magnesium substrate. More recently, Ignat 7) studied the laser cladding of aluminium on magnesium alloys WE43 and ZE41. The resulting microstructure was analysed and some mechanical properties were determined.…”

Laser cladding of aluminium powders was performed on pure magnesium substrates using the blown powder method. The microstructure across the laser-clad track was studied. Starting from the bottom of the laser-clad to the top surface of the track, a series of microstructures was observed: a planar growth interface of the substrate, a narrow band of ( þ ) eutectic, a narrow band of cellular structure, and finally a relatively thick layer of -Al and ( þ ) eutectic structure. The evolution of the various phases and microstructures is discussed in terms of the distribution of solute in conjunction with the Al-Mg phase diagram, temperature gradient and solidification rate, constitutional supercooling theory, and the condition for columnar-to-equiaxed crystal transition.

“…Al-enriched layers can be produced using various methods, e.g. laser surface alloying/cladding [3][4][5], diffusion treatment in molten salts [6,7], diffusion aluminizing treatment [8][9][10][11][12][13][14][15], PVD combined with annealing [16][17], cold spray with subsequent heat treatment [18,19], welding [20], and electrodeposition [21]. The findings reported in the above works suggest that it is the Mg-Al intermetallic phases forming in the microstructure of Al-enriched layers that are responsible for an increase in the hardness as well as corrosion and wear resistance of magnesium and magnesium alloy products.…”

Al-enriched layer was formed on a magnesium substrate with use of casting. The magnesium melt was cast into a steel mould with an aluminium insert placed inside. Different conditions of the casting process were applied. The reaction between the molten magnesium and the aluminium piece during casting led to the formation of an Al-enriched surface layer on the magnesium substrate. The thickness of the layer was dependent on the casting conditions. In all fabricated layers the following phases were detected: a solid solution of Mg in Al,

“…Finally, the recycling of coated elements with such layers is not complicated because aluminium is the main alloying element of Mg alloys. The techniques used to produce Al-enriched layers include: heating Mg-based components in contact with Al powder [2][3][4][5], electrodeposition [6], diffusion coating in molten salts [7,8], cold spray coupled with heat treatment [9], physical vapour deposition [10], laser processing [11,12]. Depending on the employed fabrication process and its parameters, the microstructure of the resulted coating may be composed of two continuous layers of intermetallic phases: the outer layer-Al 3 Mg 2 and the inner layer-Mg 17 Al 12, or may have an eutectic structure of (Mg 17 Al 12, phase + solid solution of Al in Mg).…”

AnAlysIs of the deformAbIlIty of two-lAyer mAterIAls AZ31/eutectIcAnAlizA możliwości odksztAłcAniA plAstycznego mAteriAłu dwuwArstwowego Az31/eutektykAThe paper present the results of physical simulation of the deformation of the two-layered Az31/eutectic material using the Gleeble 3800 metallurgical processes simulator. The eutectic layer was produced on the Az31 substrate using thermochemical treatment. The specimens of Az31 alloy were heat treated in contact with aluminium powder at 445°C in a vacuum furnace. Depending on the heating time, Al-enriched surface layers with a thickness of 400, 700 and 1100 µm were fabricated on a substrate which was characterized by an eutectic structure composed of the Mg17Al12 phase and a solid solution of aluminium in magnesium. In the study, physical simulation of the fabricated two-layered specimens with a varying thickness of the eutectic layer were deformed using the plane strain compression test at various values of strain rates. The testing results have revealed that it is possible to deform the two-layered Az31/eutectic material at low strain rates and small deformation values.
