    Corrosion behavior of aluminum-Fiber Glass composite fabricated through surface mechanical alloying in alkaline media
    (10P publishing, 3/24/2021) Shehata, O S; Ebrahim, Mohamed Refaat Mohamed; Abdel Fatah, Amr H
    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.
