“…The capacitive loop at high frequency is attributed to the charge transfer reaction in the electric double layer formed at the interface between the metal surface and the corrosive medium, where the equivalent component consists of a charge transfer resistance (R t ) parallel to a constant phase element (CPE 1 ). The inductive loop at low frequency is related to the pitting on the alloy surface, [31] and R and L are the corresponding parameters for the pitting.…”

“…[16,28,29] It has been reported that elements such as Sn, Si, Cd can promote the activation dissolution of the aluminum anode and make the anode potential more negative. [11,30,31] According to the above discussion, developing quaternary alloys based on the Al-Zn-In alloy is of great help to improve the performance of aluminum sacrificial anodes.…”

Overcoming the reduction of current efficiency and stacking of corrosion products on the surface of Al–Zn–In sacrificial anodes after long‐term use is of great significance for Al–Zn–In alloy as an anode material for cathodic protection of steel structures in seawater. In this study, four different sacrificial anode materials were prepared based on the Al‐6Zn‐0.03In (wt%) alloy without and with the addition of alloying elements of Sn, Cd, and Si, respectively. The influence of the addition of Sn, Cd, and Si on the microstructure and electrochemical performance of the Al–Zn–In anode was investigated by optical microscopy and electrochemical measurements. The results show that the introduction of Sn, Cd, and Si changes the microdendrite structure of Al–Zn–In to equiaxed grain. The added Sn, Cd, and Si alloys have more negative and stable working potential and uniformly dissolved morphology. The actual capacity and current efficiency of aluminum alloys increase from 2,000.6 Ah/kg and 70.7% of Al–Zn–In alloy to 2,539.4 Ah/kg and 88.6% of Al–Zn–In–Sn, 2,437.3 Ah/kg and 85.5% of Al–Zn–In–Cd and 2,500.4 Ah/kg and 88.8% of Al–Zn–In–Si alloys, respectively.

“…Recently, MGs have been also identi ed as the promising materials for high-velocity impact applications, in which their shock responses grew in considerable importance [5][6][7][8][9]. For instance, Wen et al [10] reported that the CuZr MGs demonstrates an overdriven plastic state rather than a single elastic shock wave with the piston velocity increasing. It was also found that the increase in Cu content led to the higher resistance to plastic deformation.…”

In this work, the shock wave response of a pore-embedded CuZr metallic glass (PEMG) under different impact velocities (0.5–1.5 km/s) and initial temperatures (300–600 K) was evaluated through the molecular dynamics (MD) simulation. The results indicated that the nucleation and growth of nanoscale shear events around the pore were the dominant mechanisms for plastic deformation under the shock wave. It was also found that the increase in the impact velocity led to the filling of pore, which was due to the structural softening and the local temperature increment in the vicinity of pore. Moreover, the spall event originated from the formation and coalescence of tension transformation zones, leading to the formation of nanovoids in the system. At higher velocities, the spallation was accompanied with the formation of more nanovoids with smaller sizes, inducing the brittle failure in the system. The MD outcomes also showed that the increase in initial temperature decreased the shock pressure and flow shear stress and led to the smoother spallation in the PEMG.

This study focused on the corrosion and electrochemical behaviour of aluminium alloys (AlSi9Cu5, AlZn10Si8Mg1, AlZn4Mg1In, AlSi5Mg8 and AlSi5Mg8In) as potential galvanic coatings for steel. The properties of alloys were observed in solutions of artificial rain and seawater as well as in the atmosphere. Electrochemical properties were monitored using DC techniques (open‐circuit potential, zero‐resistance ammetry). The experiments showed promising corrosion and electrochemical behaviour characteristics for AlZn10Si8Mg1 and AlSi5Mg8In alloys, which had properties similar to those of zinc.
