In order to improve the wear resistance of aluminum alloy, in-situ synthesized TiB 2 and Ti 3 B 4 peritectic composite particulate reinforced metal matrix composite, formed on a 2024 aluminum alloy by laser cladding with a powder mixture of Fe -coated Boron, Ti and Al , was successfully achieved using 3-KW CW CO 2 laser. The chemical composition, microstructure and phase structure of the composite clad coating were analyzed by energy dispersive X-ray spectroscopy (EDX), SEM, AFM and XRD. The typical microstructure of the composite coating is composed of TiB 2, Ti 3 B 4, Al 3 Ti , Al 3 Fe and α- Al . The surface hardness of cladding coating increases with the amount of added Fe -coated B and Ti powder which determines the amount of TiB 2 and Ti 3 B 4 peritectic composite particulate. The nanohardness and the elastic modulus at the interface of the TiB 2 and Ti 3 B 4 peritectic composite particulate/matrix were investigated using the nanoindentation technique. The results showed that the nanohardness and the reduced elastic modulus from the peritectic composite particulate to the matrix is a gradient distribution.
