Electrochemical investigation on the effects of sulfate ion concentration, temperature and medium pH on the corrosion behavior of Mg–Al–Zn–Mn alloy in aqueous ethylene glycol

The Corrosion Features of Q235B Steel under Immersion Test and Electrochemical Measurements in Desulfurization Solution

“…R t value increased first and then decreased, reaching the maximum value on the 21st day. Theoretically, R t was only determined by the charge-transfer-controlled corrosion and inversely proportional to V corr [ 25 ]. Thus, the change of R t demonstrated that V corr decreased with time for 21 days and then increased after 21 days.…”

Influence of dielectric barrier plasma treatment of ZnMgAl alloy‐coated steel on the adsorption of organophosphonic acid monolayers

“…Thus, the ODPA adsorption led to a partial etching of the surface passive film, explaining the change in the metal ratios: Mg was preferentially dissolved during ODPA adsorption, while the aluminium oxide seemed to be the most stable metal. This behaviour can be explained by the low stability of Mg oxides and carbonates in acidic media 2 …”

“…ZnMgAl alloys are widely used nowadays due to their high corrosion resistance when compared with pure Zn coatings or its binary alloys. [1][2][3] Additionally to the corrosion resistance, other properties of these coatings are of interest such as wettability and adhesive properties. Recently, the use of plasmas as surface treatment has gained much attention as a dry and therefore cost-efficient and environment-friendly process.…”

Surface modification of ZnMgAl-coated steel by dielectric-barrier discharge plasma

“…1,2 These Zn alloy coatings have attracted a lot of attention in the eld of lightweight constructions, although until now the research has been mostly oriented to corrosion studies. [1][2][3][4] However, these alloys must also demonstrate their suitability for adhesion-related processes, which play an important role when it is necessary to apply additional coatings (painting), or adhesives (when joining in multimaterial structures, for example). Within this context, it is of great interest to investigate surface treatments that permit a tuning of the surface properties of the alloy to specic applications.…”
