Effect of Ti on the Mechanical Properties and Corrosion of Cast AZ91 Magnesium Alloy
Ti addition to AZ91 alloy was been investigated with conventional casting. The microstructure and mechanical property were examined. The Corrosion resistance of all the different Ti addition content alloy was studied in 3.5% NaCl solution through weight loss measurement in constant immersion conditions and potentiodynamic polarization experiments. The results show that addition of Ti with an am...
متن کاملThe Effect of Environmental Parameters on the Corrosion Behavior of Simple Shear Extruded AZ91 Magnesium Alloys
In this study, the effects of forming method (extrusion) and environmental factors (solution pH and temperature) on the corrosion performance of AZ91 magnesium alloys were investigated using potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM) and salt spray techniques. The polarization test results of the specimens showed that simple sh...
متن کاملstudy of morphology of oxide film formed on magnesium alloys in casting conditions (az91)
morphology of surface oxide film formed during pouring of molten magnesium alloy has been investigated. due to surface turbulence during casting, the oxide film necessarily makes folded cause in a dry surface to dry surface mode creating a double oxide film with the volume of air that can be encapsulated between folds of the film and this led to make gas bubbles or shrinkage cavities form. thes...
متن کاملComparison of Electrochemical Methods for the Evaluation of Cast AZ91 Magnesium Alloy
Linear polarization is a potentiodynamic method used for electrochemical characterization of materials. Obtained values of corrosion potential and corrosion current density offer information about material behavior in corrosion environments from the thermodynamic and kinetic points of view, respectively. The present study offers a comparison of applications of the linear polarization method (fr...
