The 0.3%Y 2 O 3 /0.3%La 2 O 3 /0.3%Al 2 O 3 /Cu composite was prepared by oxygen and nitrogen atomization spray deposition technique, internal oxidation, and then treated by annealing at different temperatures. Physical properties such as microstructures, fracture appearance, hardness, strength, electrical conductivity, and arc erosion surface of the composite were investigated. The experimental results show that with an increase in the annealing temperature, the grains of the composite grow up obviously and the electrical conductivity of the composite increases gradually, while the hardness and the tensile strength decrease. When the annealing temperature reaches 1000°C, the matrix grains begin to appear as annealing twins. The tensile fracture morphology of the composite that has been treated by annealing at 700°C for 2 h shows a huge number of large and deep dimples, in which the metallic oxide particles exist. The fracture mode of the composite is the microporous polycondensation plastic fracture. The arc erosion surface shows a large number of paste-like coagulum and bubbles.

“…Electroless plating has been recognized as one of the most eective techniques for preparing metal-coated ceramics powders. In recent years, copper-coated Al 2 O 3 , graphite, cenospheres and SiC powders prepared by electroless copper plating have found extensive application in elds of copper matrix composites, anode material for lithium-ion batteries, high-current brush, EMI shielding, and catalysts [2]. Al 2 O 3 has been widely used in many elds due to its good mechanical and anticorrosion properties, etc.…”

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.

Cu is a well known heat sink material due to its high thermal conductivity.However, its coefficient of thermal expansion (CTE) is high. One of the most promising solutions for reducing it is to reinforce copper with carbon nanofibres (CNF) because of their low CTE. To exploit the properties of the CNFs a good dispersion of the reinforcement within the matrix must be achieved. One of the processing methods used to obtain a homogeneous CNF distribution is coating the CNF with Cu using electrochemical deposition. In this paper, the effect of the carbon structure on electroless deposition technique is studied. Different CNF have been compared: herringbone (HB), platelet (PL) and longitudinally aligned (previously heat treated) (LAHT). Herringbone and Platelet CNF were heat treated at 2750ºC for 30' which resulted in a structure resembling graphite with loops at the fibre surface. These loops are responsible for an enhancement of the copper coating. It is shown that the Cu coverage in electroless deposition is high for the graphene plane and poor at the edges of the plane.
