Abstract
Dissolution reaction control of aluminum in 2M KOH alkaline media was achieved through surface
mechanical alloying SMA with dielectric Fiber glass‘FG’ powder. A significant decrease corrosion rate
from 0.867 for blank Al to 0.0002 mm y−1 for SMA Al with FG powder previously etched after 15 min;
surface mechanical attrition treatment ‘SMAT’; Formed surface metal matrix Al/FG composites
layers on Al anodes have attractive electrical properties. Its analysis obtained using X-Rays Diffraction
XRD, scanning electron microscopy SEM. Used three electrochemical techniques EIS, CV and PDP
indicate corrosion resistance improvement in 2M KOH correspond to inhibition efficiency reaches
99.81%. Such inhibition encourage for forming efficient and safe air batteries for interesting
applications using Al anodes after consecutive SMAT & SMA processing.
