Abstract
This study investigates the effects of ferromanganese nanoparticles additions on the hardness,
impact energy and wear behaviour of a conventional(C=3.907%, Si=2.259%, Mn=0.509%, P=0.093%,
S=0.081%) grey cast iron. The cast iron scraps were melted in a 40kg silicon crucible pit type furnace
with and without addition of ferromanganese. A green sand mould of dimension 15 × 15 × 200mm was
used for the production of the cast samples. The results obtained show an improvement in mechanical
properties andwear resistance of the alloyed cast iron compared to the conventional cast iron. Comparison
was also made to an earlier work in which microsized ferromanganese particles was used. It was found
that smaller quantity of ferromanganese nanoparticles presented a better mechanical and wear properties.
