Özet
In this study, the
microstructure and corrosion properties of Vermicular Graphite Cast Iron (VGCI)
produced via different methods and parameters were investigated. VGCI was
produced from a base ductile iron material using different proportions of
vermiculariser and inoculant. Copper was added to a group of samples as an
alloying element. The microstructures and corrosion properties of samples were
investigated in saltwater media. The effects of production parameters on the
microstructure and corrosion behavior were determined. It was observed that as
the ratio of vermiculariser applied was increased, the vermicular graphite
ratio and vermicularity was also increased. The matrix grain size decreased while
the inoculant and pearlite phase ratio increased due to the addition of copper.
In electrochemical corrosion studies, VGCI was superior in corrosion resistance
compared to SGCI and addition of vermiculariser, inoculants and copper was
found effective in improving the corrosion resistance of the VGCI material.
