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 )
