description |
Metal Matrix Composite has become an attractive alternative in various
applications especially in automotive and aerospace industries nowadays. Therefore,
in order to study the characterization of Silica Sand Nanoparticles-Iron Based
Composites (Fe-SiO:z) using Nitrogen atmosphere as sintering environment, samples
were fubricated by mixing pure iron with different weight percentages (5%, 10%,
15% and 20%) of silica sand nanoparticles and undergone several testing and
observation before being evaluate.
The silica sand nanoparticles-iron based composites were developed by
powder metallurgy technique and being sintered in Nitrogen atmosphere at 1100°C.
The characterization that being evaluated include physical properties (density of
green and sintered silica sand nanoparticles-iron based composites), microstructure
analysis (Optical Microscopy & FESEM), elemental composition (EDX Analysis)
and mechanical properties (micro hardness test of silica sand nanoparticles-iron based
composites).
The research shows densities were reduced from pure iron to 20wt% of silica
sand nanoparticles. However, there were increments in each density of the composite
after being sintered which at the same time improved its hardness as well. During
sintering, the microstructure also exhibits changes in porosity, pore size also pore
shape and with the high rate of atomic motion progressively (diffusion) leads to
growth of bonds between particles, shown by the microstructure analysis being
conducted.
Theoretically stated those properties will improved after sintering process
were proven and the composite with highest weight percentage of silica sand
nanoparticles (20wt%) offered the best characteristics compared to others. |
