It is well known that oxidation of ferrous to ferric iron by water can generate molecular hydrogen (H2), with the most widely recognized natural manifestation being serpentinization olivine and pyroxene in ultramafic rocks. A less yet extremely important source H2 are peralkaline igneous intrusions, where spectacular enrichments documented from fluid inclusions as free gas migrating through fra...

In this study, the effects of intermetallic compounds (Mg17Al12 and Al8Mn5) on Mg-Al layered double hydroxide (LDH) formation mechanism corrosion behavior an in-situ LDH/Mg(OH)2 steam coatings AZ80 Mg alloy were investigated. Citric acid (CA) was used to activate surface during pretreatment process. The first pretreated with CA then subjected a hydrothermal process using ultrapure water produce...
