Role of YSZ Particles on Microstructural, Wear, and Corrosion Behaviour of Al-15%Mg2Si Hybrid Composite for Marine Applications

Original language description

Recently aluminum metal matrix composites (MMCs) achieved considerable attention as a new field of materials for high-performance applications. Aluminum-based composites are being extensively utilized in aerospace, automotive, and marine applications. In this study, the main focuses include examining the microstructural alteration, mechanical property, sliding wear behavior, and corrosion properties of Al-15%Mg2Si composites added with different content of yttria-stabilized zirconia (YSZ). Al-15%Mg2Si composites with the different contents of YSZ (0, 3, 6, and 9 wt. %) were fabricated using the stir casting technique. The effect of these particles as reinforcement on the microstructural, hardness wear, and corrosion characteristics, were studied by means of optical microscopy (OM), scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS), Vickers hardness tester, Linear Reciprocating Tribometer (LRT) and electrochemical test. The results showed that the introduction of YSZ particles substantially affects the microstructural, mechanical properties, wear, and corrosion behavior of the Al-15%Mg2Si composite. The average size of the primary particles in the base composite is 137.78 µm which was reduced to 88.36 µm with the addition of 9 wt. % YSZ. The aspect ratio of Mg2Si particles also decreased from 3, for the base composite, to 1.27, in the composite containing 9 wt. % YSZ. Moreover, the hardness value displays an incremental trend from 102.72 HV, as recorded for the base in-situ composite, to 126.44 HV, in the composite added with 9 wt. % YSZ. On top of that, the Al-15%Mg2Si-9%YSZ demonstrates exceptional wear resistance with the lowest wear rate of 0.46 mm3/km under 25 N applied load. Its average coefficient of friction (COF) is recorded at 0.42 which is lower than both 3 and 6 wt. % of YSZ containing composites. The smoother worn surface in Al-15%Mg2Si-9%YSZ hybrid composite implies that the abrasion phenomenon as dominant wear behavior is milder than the other fabricated composites. On top of that, the Al-15%Mg2Si-9%YSZ also possesses optimum corrosion resistance. The corrosion rate is 0.1050 mmpy compared to that of the in-situ composite, which is 0.1203 mmpy.
