Abstract: A novel multi-layer spray deposition technology was developed, by which 6066Al/SiC_p(+Gr) composites were manufactured. The matrix is of rapid cooling rate and large excess solid solubility. SiC particles distribute uniformly in the matrix with clear interface. Extrusion was conducted to improve the microstructure and mechanical properties. SiC particles can be broken up and rearranged. After T6 heat treatment, the final material shows low porosity and good mechanical properties. The introduction of small amount of graphite particles into the preform can improve the damping property.
