“…It usually ranges between 1 and 100 nm, [218][219][220][221][222][223] but values up to 50 lm have been reported for growth in strongly oxidative environment. [224][225][226] In water with strong oxidative chemistry, as during plasma treatment, thick and fast growing oxide layers can be expected on metal electrodes. In other liquids, different types of layers are formed through analogous processes, as, e.g., nitride layers in liquid nitrogen and carbon enriched layers in hydrocarbons, under influence of reactive nitrogen species and carbonaceous species, respectively.…”

The interaction of plasma with liquids has led to various established industrial implementations as well as promising applications, including high-voltage switching, chemical analysis, nanomaterial synthesis, and plasma medicine. Along with these numerous accomplishments, the physics of plasma in liquid or in contact with a liquid surface has emerged as a bipartite research field, for which we introduce here the term "plasma physics of liquids." Despite the intensive research investments during the recent decennia, this field is plagued by some controversies and gaps in knowledge, which might restrict further progress. The main difficulties in understanding revolve around the basic mechanisms of plasma initiation in the liquid phase and the electrical interactions at a plasma-liquid interface, which require an interdisciplinary approach. This review aims to provide the wide applied physics community with a general overview of the field, as well as the opportunities for interdisciplinary research on topics, such as nanobubbles and the floating water bridge, and involving the research domains of amorphous semiconductors, solid state physics, thermodynamics, material science, analytical chemistry, electrochemistry, and molecular dynamics simulations. In addition, we provoke awareness of experts in the field on yet underappreciated question marks. Accordingly, a strategy for future experimental and simulation work is proposed.

“…Zheng et al [11] studied the corrosion process of Al-Mg-Si alloys in NaCl solution, indicating that the corrosion attack starts from the area around the second phase. Nabhan [12] studied the effects of the pH value and the heat treatment on the corrosion behaviours of aluminium alloys. The results indicated that alloying elements have an influence on the corrosion resistance of the passivation film.…”

The corrosion behaviours of Al-Mg-Si alloys were studied in different Cl − concentrations by means of scanning electron microscopy, transmission electron microscopy and electrochemical experiments. The results show that the corrosion behaviours of Al-Mg-Si alloys are closely related to the Cl − concentration. With an increase in Cl − concentration, the corrosion rate increases sharply by facilitating the process of chemical and electrochemical reactions. In 2.0 wt.% NaCl solution, slight pitting corrosion occurred around the MgSi phase, but corrosion trenching was not found around the Fe-Mn-Si phase. In 3.5 wt.% NaCl solution, the alloy appeared localized corrosion dominated by intergranular corrosion attack. In 5.0 wt.% NaCl solution, the alloy presented serious overall corrosion, and the passivation platform of the polarization was not obvious. Furthermore, an appropriate corrosion mechanism according to polarization and electrochemical impedance spectroscopy was proposed for the Al-Mg-Si alloy in NaCl solution. In addition, the corrosion rate influenced by different Cl − concentrations was discussed in detail.
