“…For example, it is well known that Al-Mg alloys, especially those with high content of Mg, are susceptible to pitting corrosion [6][7][8]. So many kinds of technologies have been developed to reduce the pitting corrosion problem [9][10][11][12][13][14][15][16][17][18]. Al-Mg electromagnetic shielding wire is served in magnetic field, however, the influence of this special environment on its corrosion behavior is not clear and the method to increase the corrosion resistance of this alloy is lack of research.…”

Effect of magnetic field and rare earth on the corrosion behavior of Al-3.0 wt.%Mg alloy in 3.5 wt.% NaCl solution was investigated by immersion test and electrochemical measurement. The results indicated that a horizontal magnetic field would increase the corrosion potential (E corr), impede the growth of pitting holes and reduce the corrosion current density i corr and corrosion rate of Al-3.0 wt.%Mg-xR E alloys. Proper content of R E would increase the corrosion resistance of Al-3.0 wt.%Mg alloys. Excessive R E would enhance the effect of magnetic field on the pitting corrosion sensibility and increased the corrosion rate of Al-3.0 wt.%Mg alloys due to the increase of the number and the size of the second phases.

Abstract:A nonlinear cumulative evolution model for corrosion fatigue damage was proposed. Corrosion fatigue damage was considered as a nonlinear cumulative result of stress corrosion damage and fatigue damage. The influences of stress corrosion damage and fatigue damage on corrosion fatigue damage and damage evolution life were studied from a phenomenological point of view. The relevant damage parameters were determined by the experimental results of the LY12CZ aluminum alloy, and the corrosion fatigue life evaluation model based on damage evolution law was established. The corrosion fatigue life predicted by evaluation model agrees well with the experimental result. The damage evolution model in this study can provide a new method for theoretical research and life prediction of corrosion fatigue.

“…Due to their excellent corrosion resistance to sea water, aluminum-magnesium alloys are widely used in naval applications where they are exposed to severe hydrodynamic conditions [7, 12, and 14]. Regardless of the presence of chloride, heterogeneities either it the metal itself, the medium or in the exposure conditions, generally lead to the common phenomenon of pitting corrosion of aluminum-magnesium alloys [8,15]. This type of local corrosion often occurs in forms of crevices around the noble, iron-containing intermetallic particles as a result of micro galvanic coupling between them and the active surrounding solid solution aluminum matrix [1].…”

Aluminum-magnesium alloys are specially used in high speed boats, submarines, desalination systems, etc. In this re-search the electrochemical impedance spectroscopy technique was utilized to study the flow accele-rated pitting corrosion behavior of this alloy in 3.5% NaCl solution. To do so, impedance spectra of the samples after 20h of exposure to the test solution at a rotation speeds were investigated. SEM (scanning electron microscopy) method was utilized to investigate the changes in the surface of the samples. Results indicated that under static and dynamic con-dition, the surface growth rate of the pits increases with time. Moreover, at -0.9 V upon altering the flow condition from static to dynamic, the surface growth rate of the pits and their surface fraction increases while the corrosion resistance of the passive layer is time dependent.
