“…Such a defect-less bonding could not be observed in the microstructure of the previous samples. Many authors also reported that a strong bonding would be formed between ceramic particles and metal matrix if copper is coated on the surface of ceramic particles [30,31]. Line EDAX analysis for sample S4 indicated that white-colored areas are related to the presence of copper in the matrix of aluminum.…”

Ceramic particles typically do not have a sufficiently high wettability for incorporation into molten metal during aluminum matrix composite manufacturing. Metallic coatings on ceramic particles could improve their wettability by the molten aluminum and hence provide a better bonding between the reinforcement and matrix. In this study, micrometer-sized SiC particles were coated by copper, nickel, and cobalt metallic layers using electroless deposition method. These metallic layers were produced separately prior to ceramic incorporation into molten pure aluminum, in order to compare their effects on the microstructure and mechanical properties of the produced composites. The experimental results showed that copper was the most effective and nickel the least effective of these coating metals for incorporation of the SiC particles into the molten aluminum. It was additionally found that the composite, which contained the copper coated SiC particles, produced the highest microhardness and tensile strength, while that fabricated with the cobalt-coated SiC particles produced the lowest microhardness and tensile strength.

In this study, Cu-coated Al2O3 composite powders were synthesized by using electroless plating method. The inuence of the plating bath composition and ceramic powder concentration on the Cu plating was characterized by scanning electron microscopy, energy dispersive spectroscopy, and X-ray diraction techniques. The results showed that the electroless bath composition plays an important role for the structure of nano core-shell Al2O3/Cu composite powders. The content of copper in the composite powders could be eectively controlled by adjusting the content of copper sulfate and formaldehyde in the plating solution. Furthermore, the pretreatment of the Al2O3 powders is also a key factor to form a uniform shell copper layer coating on Al2O3 particles.

“…It has been established that adding certain Mg and Si elements in the aluminum system could be beneficial for the pressureless infiltration of the SiC preform by aluminum [7][8][9]. For instance, Choh and Oki [9] observed that the addition of Si to Al decreased the incubation period of wetting at temperatures between 1173 and 1373 K. The second method to increase the surface 2 Advances in Materials Science and Engineering energy of the particle surface involves pretreatment of the SiC particles with several surface coating technologies, such as the sol-gel method or high temperature oxidation to obtain silica coatings [10,11] by electroless plating [12,13]. Among the above techniques, electroless plating is considered more effective due to its low cost, easy-to-control procedure, and large-scale production abilities.…”

A nickel (Ni) coating was deposited on the surface of silicon carbide particles (SiC p ) through electroless plating and we characterized the morphology and phase structure of the coating and the pressureless infiltrated SiC p /Al composites. The effect of Ni coatings on the thermal conductivity of the composites was examined and analyzed with three-dimensional video microscope, scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction microscope (XRD), and finite-element. The results show that a continuous and uniform coating with a certain thickness (around 3.5 m) can be formed on the surface of SiC p . With the addition of the Ni layer, there are some intermetallics Ni 3 Al but no interfacial carbide Al 4 C 3 , which improves the wettability and the thermal conductivity of the composites. The experiments and simulations both show that Ni coatings do not substantially decrease the overall thermal conductivity of the composite, although the thermal conductivity of Ni itself is lower than Al and SiC by a factor of 1.
