Abstract : In this study, the effect of addition of Zn element on the electrochemical corrosion resistance of Mg5Al1Ti magnesium alloy produced by conventional casting method was investigated. Master alloy Zn addition is 2% and 4%. The corrosion test was carried out in a 30gr NaCl / l + 10ml HCl / l solution with potentiodynamic polarization measurement methods. Potentiostatic polarization corrosion experiments were performed using a computer controlled Gamry model PC4/300mA potentiostat / galvanostat with DC105 corrosion analysis software. Scanning Electron Microscope, stereo microscope and X-ray diffraction analysis were used for microcharacterization. Corrosion current density and corrosion potential values were measured from the potentiodynamic polarization curves of the investigated alloys. The Mg5Al1Ti master alloy containing 4% Zn element exhibited the lowest current density at 1.55mA/cm2. Keywords: Mg5Al1TiAlloys, ZnAddition, Casting, CorrosionResistance.
