“…17) Nickel is frequently used for coating reinforcement particles used with aluminum-based composites. [18][19][20][21] It has been found that nickel coatings can improve the wetting behavior of carbon bers by molten aluminum and limit ber segregation to obtain a homogeneous reinforcement distribution. Our previous study revealed that an improvement in the wettability of a magnesium alloy on a nickel-coated graphite sheet was achieved through the dissolution of the nickel into the liquid magnesium alloy.…”

Magnesium-calcium alloy composites reinforced with nickel-coated vapor-grown carbon bers (VGCFs) were fabricated using a compo-casting process. Then, the microstructures and mechanical properties of these composites were investigated. The Mg-5Al-3Ca (AX53) alloy exhibited a dendritic microstructure with a coarse lamellar (Mg, Al) 2 Ca phase along the grain boundaries instead of the irregular β-Mg 17 Al 12 phase found in the Mg-5Al alloy. For the 0.5% Ni-coated VGCF-reinforced AX53 alloy composite, the VGCFs were well dispersed in the matrix, with the nickel coating diffused into the metal. Al 3 Ni compounds formed both inside the grains and on the grain boundaries. The ultimate tensile strength (UTS) and strain-hardening of the AX53 alloy, in comparison with the Mg-5Al alloy, were improved signi cantly to the point of fracture. Furthermore, an increase in the UTS of the composite was achieved with the addition of 0.5% VGCFs, along with an increase in the total elongation, which could mainly be attributed to the strain hardening during a larger strain. The 0.2% yield stress was slightly improved as a result of the small amount of introduced Ni-coated VGCFs. However, the elongation dropped for the 1.0% VGCF-reinforced AX53 alloy composites, which led to a low strength similar with that of the AX53 alloy.

“…Aluminium matrix composites have obtained a great interest, because they combine high corrosion resistance, low weight, low cost, high specific strength and perfect wear resistance [22][23][24][25]. Aluminium matrix composites have been investigated by many researchers [26][27][28][29][30][31][32][33]. However, B 4 C and ZrSiO 4 reinforced aluminium matrix composite has not attracted enough attention.…”

“…For broadening its application it is of particular interest to use processing problems coatings (copper, nickel, silicon carbide or titanium boride) and thermal treatments (the annealing of fibres to eliminate gases adsorbed on the surface of reinforcement) are applied. It provides the decrease of the contact angle and in consequence -improvement of wettability [2][3][4][5][10][11][12].…”

In the paper the microstructures of WE43 matrix composites reinforced with carbon fibres have been characterised. The influence of reinforcement type and T6 heat treatment (a solution treatment at 525°C for 8 h, a hot water quench and a subsequent ageing treatment at 250°C for 16 h) on microstructure have been evaluated. The light microscope and scanning electron microscope investigations have been carried out. No significant differences in samples reinforced with non-coated textiles have been reported. The substantial changes in sample reinforced with nickel-coated textile have been observed. The segregation of alloying elements to the matrix-reinforcement layer has been identified. The T6 heat treatment caused the appearance of disperse precipitates of β phase, but the process cannot be considered as satisfactory (irregular distribution, low volume fraction, relatively large size).
