説明

This study investigated the effects of Fe and SiC particle additions on mechanical properties and corrosion behavior of Mg-9 mass% Al-1 mass% Zn (AZ91) composite fabricated by powder metallurgy (P/M). The P/M forged AZ91-SiC composites showed noticeable increases in Young’s modulus and compressive yield strength compared to the monolithic AZ91 alloy, which was related to grain refinement and the content of SiC in the P/M composite. Corrosion rates of AZ91 matrix composites were further correlated to both SiC and Fe additions and the boundary length between AZ91 matrix and Fe particles. The insulating behavior of SiC particles also explained their smaller influence on the corrosion rate of P/M AZ91 compared with conductive Fe particles. The addition of SiC particles also inhibited the galvanic corrosion between AZ91 matrix and Fe particles. This study showed that corrosion rate of AZ91 may be controlled by the boundary length between AZ91 matrix and Fe particle.
