The effects of NaF concentration on electrochemical and corrosion behavior of AZ31B magnesium alloy in a composite electrolyte

Abstract

Electrochemical and corrosion behavior of AZ31B magnesium alloy have been investigated in composite solution of MgSO4–Mg(NO3)2 (0.14 mol L−1 MgSO4, 1.86 mol L−1 Mg(NO3)2) under different sodium fluoride (NaF) concentrations.

Development of layer‐by‐layer assembled thin coatings on aluminium alloy AA2024‐T3 for high resolution studies of local corrosion processes

“…However, instead a potential shift in the negative direction was observed as the BL number increases. This behavior was reported with alloys containing magnesium, 25 aluminium, 26 aluminium alloys 27 and ferrous materials. 28 No significant changes were observed in the cathodic branch of the Tafel plot for 1 BL and 4 BL samples, indicating that the corrosion protection effect is based on the suppression of anodic metal dissolution resulting in a negative shift of the free corrosion potential.…”

Facile synthesis of Tb-decorated graphene oxide: electrochemical stability, hydrogen storage, and corrosion inhibition of Mg AZ13 alloy in 3.5% NaCl medium

“…The conventional epoxy coating does not contain strong acceptor functional groups and is also easy to peel out from the alloy surface due to which the grain boundary of epoxy coated Mg alloy was affected which in turn is due to the intergranular corrosion, as shown in the above surface studies of epoxy coated Mg alloy surface. [46][47][48][49][50][51] However, Mg alloy coated by the Tb functionalized graphene oxide showed that the propagation of pitting corrosion stops due to the changes in the electron ow of Tb 3+ between the alloy surface and electrolyte medium. Due to this, the corrosion current decreased and corrosion potential increased.…”
