“…According to the results of EPMA element mapping and corroborated with reference [ 34 ], Figure 12 a,b graphically represent the corrosion behaviors of both bare and ALD-HfO 2 /AMC in the NaCl (aq) solution. For bare AMCs, the significant influence of SiC particles on corrosion is evident, particularly in forming micro-cracks and directing corrosion.…”

In recent years, aluminum matrix composites (AMCs) have attracted attention due to their promising properties. However, the presence of ceramic particles in the aluminum matrix renders AMCs a high corrosion rate and makes it challenging to use traditional corrosion protection methods. In this study, atomic layer deposition (ALD) techniques were used to deposit HfO2, ZrO2, TiO2, and Al2O3 thin films on AMC reinforced with 20 vol.% SiC particles. Our results indicate that the presence of micro-cracks between the Al matrix and SiC particles leads to severe micro-crack-induced corrosion in Al-SiC composites. The ALD-deposited films effectively enhance the corrosion resistance of these composites by mitigating this micro-crack-induced corrosion. Among these four atomic-layer deposited films, the HfO2 film exhibits the most effective reduction in the corrosion current density of Al-SiC composites in a 1.5 wt% NaCl solution from 1.27 × 10−6 A/cm2 to 5.89 × 10−11 A/cm2. The electrochemical impedance spectroscopy (EIS) investigation shows that HfO2 deposited on Al-SiC composites has the largest Rp value of 2.0 × 1016. The HfO2 film on Al-SiC composites also exhibits effective inhibition of pitting corrosion, remaining at grade 10 even after 96 h of a salt spray test.

Magnesium (Mg), with a density of two-thirds of aluminium (Al) and one-fourth of steel, has become one of the most attractive materials for automotive and aerospace industries owing to the obligation to reduce fuel consumption and gas emissions. However, the poor mechanical property of Mg is one of the most significant barriers to its widespread use. The most widely used method to increase the use potential of Mg is the development of Mg matrix composites. This review focuses on the mechanical properties of recent Mg matrix composites. The effect of different reinforcement materials on the mechanical behaviour and failure mechanisms of Mg matrix composites was evaluated in detail.

“…Such a brittle phase is often detrimental to the mechanical properties of the composites. According to the EDS mapping results, a few Cu-rich phases remaining in the ceramic-rich layers can be found due to the limited diffusion capacity of the Cu element in the reinforcement-rich areas [18,21]. in the ceramic-rich layers can be found due to the limited diffusion capacity of the Cu element in the reinforcement-rich areas [18,21].…”

Nacre-inspired metal matrix composites have received much attention due to their excellent deformation coordination ability, which can achieve the synergy of strength and ductility. The preparation of nacre-like Al matrix composites by freeze casting has been a promising application, but the continuous ceramic-rich layer affects the corrosion resistance of the composites, facing complex corrosion problems during service. In this work, the microstructure and corrosion behavior of the nacre-inspired (TiBw-TiB2)/Al composites fabricated by freeze casting and squeeze casting were systematically studied. The results indicated that the Al layers and ceramic-rich layers had little change, about 35 μm and 31 μm, respectively, with an increasing ratio of the Ti/TiB2. Meanwhile, a high Ti/TiB2 ratio resulted in an increase in the Fe-Ti intermetallic phases, which was detrimental to the corrosion performance of the composites and was prone to pitting. The electrochemical test results showed that the 3Ti7TiB2 composite had the lowest corrosion current density (15.9 μA) and intergranular corrosion depth (231 μm), indicating that it had the best corrosion resistance, which can be attributable to its stable and dense passivation film. Two different corrosion phenomena during the intergranular corrosion test existed in the present nacre-inspired (TiBw-TiB2)/Al composites: intergranular corrosion in the Al matrix layer and pitting corrosion in the ceramic-rich layer. Among all the composites, the corrosion depth of the 3Ti7TiB2 composite was the smallest and significantly less than that of the 2024Al alloy. In addition, the continuous ceramic-rich layer acted as a corrosion channel during corrosion, significantly degrading the corrosion resistance of the nacre-like Al composites.
