Among the various causes of free chlorine consumption in drinking water distribution networks, the internal corrosion of pipes has not been so far seriously considered. This work focused on the corrosion study of cast iron, as a representative material of those networks, in non-chlorinated and chlorinated waters, by both electrochemical impedance spectroscopy and classical photographic observat...

Compacted graphite cast iron is a material that again comes forward of the interest of designers and foundries acquiring or improving manufacture of castings from that material. From many publications let us quote three of them from last year 1, 2, 3 . According to the European standard ISO 16 112 this material is called „compacted (vermicular) graphite cast iron“ (the abbreviation CGI that wil...

In this work, the results obtained from studying the corrosion of cast iron in freely aerated stagnant Arabian Gulf seawater (AGS) at room temperature were reported. The study was carried out using weight-loss (WL), cyclic potentiodynamic polarization (CPP), open-circuit potential (OCP), and electrochemical impedance spectroscopy (EIS) measurements and complemented by scanning electron microsco...
