Abstract The paper present.. the corrosion data of ma~nesium metal in different aqueous solutions such as NHl~l, Naf and NaCl04 of concentrations ran~ing from 0.1 to 2.0 M. Pola.-isation and optical methods have been used to evaluate the cOITosion paraDlt'ters and surface properties. The dependence of the open circuit potential, cOlTosion potential, corrosion currt'nt and Tafel slopes on the nature and concentmtion of the electrolytes has been examined. Corrosion current increases linearly with concentration of the electrolyte in all the media. The findinJ!;s further infer the corrosivity of the anions decrease in the ordt'r as CI- r no:;. The naturt' of the corrosion products formed on the surface as well as lIlorphnlogical features of the specimt'll nhtained from XRD and SEM techniques are also discussed in this communicatioII.
