چکیده
|
This work deals with the relation between microstructure and electrochemical behavior of four iron-based fecoc ternary alloys. first,the arc-melted studied alloys were characterized using differential thermal analyses and scanning electron microscopy. the established solidification sequences of these alloys show the presence of two primary crystallization phases ((fe) and graphite) as well as two univariante lines: peritectic l+δ(fe) ↔ γ(fe) and eutectic l(fe)+ c graphite. the ternary alloys were thereafter studied in nondeaerated solution of 10 -3m nahco3+10 -3m na 2so 4,at 25 ° c,by means of the potentiodynamic technique. the results indicate that the corrosion resistance of the fecoc alloys depends on the carbon amount and the morphology of the phases present in the studied alloys. copyright 2012 farida benhalla-haddad et al.
