“…Figure 7a presents the evolution of corrosion current density ( i corr ) with the increase of the carried current. The corrosion potential ( E corr ) of the current-free A1050 in 3.5% NaCl solution is −765.76 mV, which is similar to the research of Alwahib et al (2020) and Shadravan et al (2015). The corrosion current density ( i corr ) of the current-free A1050 is 7.234 × 10 −6 A/cm 2 , also in good agreement with the results reported by Sabet and Dehghanian (2018).…”

Purpose The purpose of this paper is to study the effect of current-carrying condition on the electrochemical process and atmospheric corrosion behavior of the commercial aluminum alloys. Design/methodology/approach Potentiodynamic polarization tests were performed to study the electrochemical process of the aluminum alloys. Salt spray tests and weight loss tests were carried out to study the atmospheric corrosion behavior. The corrosion morphology of the alloys was observed, and the products were analyzed. Findings The corrosion process of four aluminum alloys was accelerated in the current-carrying condition. Moreover, the acceleration effect on A2024 and A7075 was much stronger than that on A1050 and A5052. The main factors would be the differences in microstructure and corrosion resistance between these alloys. As the carried current increased, the corrosion rate and corrosion current density of the aluminum alloys gradually increased, with the protection of the corrosion product film decreasing linearly. Originality/value This is a recent study on the corrosion behavior of conductors under current-carrying condition, which truly understands the corrosion status of power grid materials. Relevant results provide support for the corrosion protection and safe service of aluminum alloy in power systems.

“…The details of how a liquid front transitions from a film to a drop shape have important implications, both for fundamental and practical applications. For instance, the ability to predict and control the speed of dewetting is inherently linked to the dynamics of the triple line (1) and is critical for developing smart self-cleaning surfaces (9)(10)(11) and more robust coating agents (12).…”

“…Carbon nanotube (CNT) reinforced metallic matrix composites are being increasingly explored to enhance various properties of the matrix materials such as strength [1][2][3][4], conductivity [5], corrosion resistance [6,7], and magnetic properties [8][9][10]. Critical to the realization of such materials with improved properties is the development of fabrication techniques providing a homogeneous dispersion of nanotubes in the metallic matrix.…”

a b s t r a c tIn this work, 2 vol% carbon nanotubes (CNTs) reinforced aluminum (Al) matrix composites of superior microstructural homogeneity are successfully synthesized using Bc equal-channel angular extrusion (ECAP) route. The key step in arriving at high level of homogeneous distribution of CNTs within Al was preparation of the powder using simultaneous attrition milling and ultra-sonication processes. Microstructure as revealed by electron microscopy and absence of Vickers hardness gradients across the material demonstrate that the material reached the homogeneous state in terms of CNT distribution, porosity distribution, and grain structure after eight ECAP passes. To facilitate comparison of microstructure and hardness, samples of Al were processed under the same ECAP conditions. Significantly, the composite containing only 2 vol% exhibits 20% increase in hardness relative to the Al samples.
