Abstract:6066Al/SiCpcomposites were developed by multi-layer spray co-deposition technology. The deposition preforms with high cooling rate were prepared. In the deposition preforms, the distribution of the reinforcing particulates is homogeneous and the interface between the reinforcing phase and the matrix is clean. After extrusion and T6 heat treatment, the materials show mechanical properties as:σb=640 MPa,σ0.2=510 MPa,E=133 GPa,δ=9.4%.
