Effect of structure on corrosion resistance of Mg-Zn-Ca alloy
Abstract
Two model Al – Mg alloys, containing 1 and 7,5% wt of magnesium, were subjected to severe plastic deformation by means of hydroextrusion This method allows to uniformly deform the material, for during the process a surrounding pressurized liquid is pushing it through the die, resulting in the extrusion The diameter of both materials was reduced from 20 to 10 mm, giving the deformation degree equal to 1,39. In order to determine the influence of deformation on the size and shape of grains the microstructure of both alloys in an initial state and after extrusion were examined with the use of light microscopy (LM). The overall influence of Mg content on the microstructure was also considered. Corrosion resistance of the materials was measured in a standard three-electrode setup, consisting of an examined sample as a working electrode, a Pt counter electrode and an Ag|AgCl reference electrode all the tests were carried out in 3,5% wt sodium chloride water based solution in an ambient temperature Open circuit potential and potentiodynamic polarization behavior of materials was determined, characteristic corrosion parameters were calculated by Tafel extrapolation method Surface of the samples after corrosion tests was further examined with the use of scanning electron microscopy (SEM), which allowed to determine the extent and character of its degradation.
