Corrosion and impedance studies on magnesium alloy in oxalate solution

A universal electrolyte for the plasma electrolytic oxidation of aluminum and magnesium alloys

“…The most popular, currently existing basic silicate electrolytes offer the creation of an oxide ceramic layer only for aluminum alloys [2,[7][8][9][10][11][12] or only for magnesium alloys [13][14][15][16][17][18]. The fundamental difference between these electrolytes is that the electrolytes intended for the oxidation of magnesium alloys contain an increased amount of alkali (up to 10 g l −1 of alkali or much higher: 4 g l −1 KOH [19-A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT 2 21]; 0.13M (7.28 g l −1 ) KOH [22]; 1.5M (84 g l −1 ) KOH [16]), while the electrolytes used for the oxidation of aluminum alloys have a lower alkali content (0.5-2.0 g l −1 of alkali [6,[23][24][25][26][27][28]).…”

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

“…Also, EDX results exhibit a higher concentration of oxygen as the corrosion reaction propagated by the attack of corrosive ion on the alloy. [39][40][41][42] Hence, the concentrations of Zn and Al decreased as the alloy surface was attacked by the corrosive ions. Fig.…”

Effect of Gadolinium Content on the Corrosion Behavior of Magnesium Alloys in 1 wt.% NaCl Solution

“…King et al [39] studied the corrosion of Mg using EIS and asserted that the electrochemical response usually displays inductive behavior with decreasing frequency. The inductive loop interpretation has been discussed in the literature and was attributed to species adsorption [40,41]. Thus, the inductive loop was ascribed to a process involving Mg + even though there was no firm evidence for the presence of the Mg + ion [42,43], or as Mg 2+ ions, or MgOH + , and to the dissolution of the protective film on the electrode surface [38].…”
