“…This mechanism could be divided into four stages: breakdown of passivity, early stages of pit growth, late stages of pit growth and repassivation phenomena. 14 The breakdown of passivity may be caused by the mechanism of chloride penetration through the oxide film, the passive layer failure mechanism, the mechanism of chloride adsorption at the oxide surface, and accelerated transfer of metal cations to the electrolyte. The formation of a micelle structure, which develops in a pit domain during its growth, plays an essential part in these mechanisms.…”

“…[12][13][14][15] Magnetic fields affect magnetic species according to their nature (ferromagnetic, paramagnetic or diamagnetic); one expects that chemical reactions involving such species will be affected by the applied magnetic field, one way or the other. Moreover, elementary physics shows that charged particles in motion, such as ions, will be subject to the Lorentz force caused by the application of a magnetic field.…”

The inhibiting effect of the cationic surfactant cetyl trimethylammonium chloride (CTAC) on the corrosion of aluminium in hydrochloric acid solutions in the presence and absence of external magnetic fields of up to 0 . 114 T has been investigated by weight loss measurements. It was found that strong magnetic fields affect the corrosion rate. The efficiency with which CTAC inhibits the corrosion of aluminium was increased in the presence of an external magnetic field. The extent of inhibition increased as the external magnetic field was increased. The magneto corrosion inhibition was explained in terms of the field assisted development of a passive layer.

“…And it's clear that F is always perpendicular to v. Thus, an external magnetic field has the ability to alter the rate of molecular transport of electrochemical species which is called the MHD phenomenon [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. The MHD flow in electrochemical systems is conveniently described by the force per unit volume acting on the solution, F MHD (N/m 3 ),…”

“…On the other hand, general corrosion of copper was found to be suppressed by magnetic fields, while its localized corrosion was found to be accelerated [13]. Magnetic fields have been reported to reduce the corrosion susceptibility of aluminum [14] and 303 stainless steel [15], but the repassivation potential of stainless steel was decreased when a 0.27 T magnetic field was applied perpendicular to the surface [16].…”

The effect of magnetic field on the pitting corrosion susceptibility of pure magnesium was investigated by stochastic approaches. Stochastic models had been applied to simulate pitting corrosion as the combination of two physical processes: pit initiation and pit growth. The results revealed that magnetic field increased the pitting corrosion susceptibility of pure magnesium. For the pit initiation process, the presence of magnetic field changed the mechanism of pit initiation from the parallel birth and death stochastic model (B1) to the parallel birth stochastic model (A3). Magnetic field increased the pit generation rate l while decreased the repassivation rate m, which indicated that magnetic field accelerated the pit initiation process of pure magnesium. For the pit growth process, magnetic field didn't change the pit growth mechanism, but it could decrease the ability of repassivation of pitting corrosion resulting in a great probability for the stable pitting corrosion to grow up with a higher growth rate and finally develop into larger pit cavity.

“…Both the E bd and the E rp values may serve as certain criteria of an anticorrosive stability: the higher the potential, the more stable the metal. 15 The corrosion current density i corr and polarisation resistance R p obtained from the potantiodynamic polarisation curves of aluminium are presented in Fig. 6 as a function of ARB cycles.…”

Pitting corrosion susceptibility of ultrafine grains commercially pure aluminium produced by accumulative roll bonding process

Ultrafine grains (UFGs) of commercial pure (CP) aluminium were produced by accumulative roll bonding (ARB) process. The relative pitting corrosion susceptibility of a coarse grained (CG) initial sample and ARB processed samples was investigated using direct current electrochemical techniques and immersion test. Applying the ARB process for eight passes was found to significantly decrease the anodic breakdown and repassivation potentials (E bd and E rp respectively) of the samples. It is also postulated that the protective characteristics of passive film were diminished through the ARB process. These results were interpreted in terms of the high defects and inhomogeneities in oxide film as well as cathodic intermetallic particles (Al 3 Fe and Al 6 Fe intrinsic inclusions). SEM observations from the sample surfaces after the immersion test confirmed these results.
