Abstract Scope |
Here Mg-xAl (x-5,10,20 wt.%) alloys were produced by high-energy-ball-milling (HEBM) and consolidated using spark-plasma- sintering at 400 °C with 200 MPa. The hardness, microstructure, and phase analysis for the alloys were investigated using Vickers’ micro-indenter, scanning electron microscopy, and X-ray diffraction, respectively. Potentiodynamic polarization and electrochemical impedance spectroscopy(EIS) studies were done using a potentiostat in 0.1 M NaCl and 0.1 M Na2SO4, respectively. Presence of species in the film formed on Mg and Mg-10Al alloy was characterized via x-ray photoelectron spectroscopy(XPS). The hardness increased with an increase in the Al content. The corrosion behavior improved on Al addition up to 10 wt.% and deteriorated for higher Al content. The corrosion behavior is discussed based on microstructural and phase changes occurring on varying Al content. The mechanism of improved corrosion behavior will be discussed. The work bring valuable insight in designing the Mg-Al based alloys. |
