Abstract
Hybrid reinforcement's novel composite (Al-Fe(3)O(4)-SiC) via powder metallurgy method was successfully fabricated. In this study, the aim was to define the influence of SiC-Fe(3)O(4) nanoparticles on microstructure, mechanical, tribology, and corrosion properties of the composite. Various researchers confirmed that aluminum matrix composite (AMC) is an excellent multifunctional lightweight material with remarkable properties. However, to improve the wear resistance in high-performance tribological application, hardening and developing corrosion resistance was needed; thus, an optimized hybrid reinforcement of particulates (SiC-Fe(3)O(4)) into an aluminum matrix was explored. Based on obtained results, the density and hardness were 2.69 g/cm(3), 91 HV for Al-30Fe(3)O(4)-20SiC, after the sintering process. Coefficient of friction (COF) was decreased after adding Fe(3)O(4) and SiC hybrid composite in tribology behaviors, and the lowest COF was 0.412 for Al-30Fe(3)O(4)-20SiC. The corrosion protection efficiency increased from 88.07%, 90.91%, and 99.83% for Al-30Fe(3)O(4), Al-15Fe(3)O(4)-30SiC, and Al-30Fe(3)O(4)-20SiC samples, respectively. Hence, the addition of this reinforcement (Al-Fe(3)O(4)-SiC) to the composite shows a positive outcome toward corrosion resistance (lower corrosion rate), in order to increase the durability and life span of material during operation. The accomplished results indicated that, by increasing the weight percentage of SiC-Fe(3)O(4), it had improved the mechanical properties, tribology, and corrosion resistance in aluminum matrix. After comparing all samples, we then selected Al-30Fe(3)O(4)-20SiC as an optimized composite.
