Electroless nickel coated fibres have been used as reinforcement for the fabrication of aluminium matrix composites by liquid processing. Uniform, continuous and well-adhered nickel coatings are obtained with different phosphorus contents. Coated carbon fibres were mixed with AA6061 aluminium powders, compacted and heated at temperatures from 650 to 950 degrees C to study the reactivity, the nickel diffusion, and the resulting interfaces. Coatings improve the wetting behaviour of carbon fibres by molten aluminium because of the formation of a transient Al-Ni intermetallic at the matrix-fibre interface, limiting fibre segregation to obtain a homogeneous reinforcement distribution. Finally, the mechanical properties of the composite have been measured through nanoindentation tests. (c) 2006 Elsevier Ltd. All rights reserved.
