Abstract The corrosion properties of common cast iron materi als in static (flowing velocity is about 0.1 m/s)and flowing seawater were teste d,and effects of graphite morphology,matrix microstructure and low alloying trea tment on corrosion properties of cast irons were analyzed.The experimental resul ts indicate that the corrosion-resistance property of flake graphite samples is superior to that of spherical graphite samples.The average corrosion rate of sph erical graphite samples,compared with other samples,was little,but its tendency of pitting corrosion is intensively obvious.For samples in static and low flowin g seawater (flowing velocity is more than 3 m/s),chemistry-electrochemistry d issolution mechanism is almost wholly responsible for their corrosion behavior.A s to sampl es in high flowing seawater (flowing velocity is equal to or more than 7 m/s),er osion-ablation behavior further accelerates chemical-electrochemical dissolution .
