  • Zn-38Al-3.5Cu-1.2Mg composite reinforced by nano SiCp was fabricated by stirring assisted ultrasonic vibration. In order to improve the abrasive resistance of the Zn-38Al-3.5Cu-1.2Mg/SiCp composite, several stabilization treatments with distinct solid solutions and aging temperatures were designed. The results indicate that the optimal stabilization treatment for the 38Al-3.5Cu-1.2Mg/SiCp composite involves a solution treatment at 380 °C for 6 h and aging at 170 °C for 48 h. The stabilization treatment leads to the formation of dispersive and homogeneous nano SiCp. During the friction wear condition, the nano SiCp limits the microstructure evolution from the hard α(Al, Zn) phase to the soft β(Al, Zn) phase. Besides, the increased amount of nano SiCp improves the grain dimension and contributes to abrasive resistance. Furthermore, the initiation and propagation of crack produced in the friction wear process are suppressed by the stabilization treatment, thereby improving the abrasive resistance of the Zn-38Al-3.5Cu-1.2Mg/SiCp composite.
