The Effect of The Cerium Addition On The ( Corrosion – Fraction Wear )  
Properties of ( Aluminum – Iron ) Base Alloy .  
Abstract :  
        The present study deals with the effect of addition cerium in the corrosion – fraction wear behavior of  with added ( 0.25% ) cerium element .  
The solution used ; salt solution ( 3%Wt.NaCl ) by weight , acidic solution (3%Vol.HCl ) by volume , weight loss method ; electrochemical method ( Tafel Extrapolation ) and microscopic examination are used for study corrosion behavior of alloy . The result of weight loss method showed different continues weight loss while the ( B ) alloy showed weight loss at the first stage of the test then showed weight gain . The result of electrochemical method ( Tafel Extrapolation ) showed the corrosion potential and corrosion current of ( A ) alloy in the salt solution was  E Corr.=-641.3 mv;I Corr.= 34.42µA/Cm2 while the corrosion potential and corrosion current for  ( B ) alloy was E Corr.= -681.6 mv ; I Corr.= 51.50 µA/Cm2. The result of weight loss method in acid solution showed convergence in the result at first hour of the test after that  ( A )  alloy showed signification superiority on the ( B ) alloy . The result of electrochemical method  ( Tafel Extrapolation ) showed the corrosion potential and corrosion current of ( A ) alloy in the acidic solution was E  Corr.= -324.7 mv ; I Corr.=19.13 µA/Cm2 while the corrosion potential and corrosion current for ( B ) alloy was E Corr. = -697.9 mv ; I Corr.=507.35 µA/Cm2. The result of fraction wear test showed significant superiority of alloy ( A ) on the alloy ( B ) .
