| description | In this study, it was aimed to investigate the microstructure, hardness and
wear behavior of graphene nanoplate (GNP) reinforced composites with Al 99.9
matrix produced by powder metallurgy. Different temperatures and times were
applied in the sintering process. The hardness values of the composites
increased as the sintering temperature and time increased. The hardness
values decreased with the increase of GNP reinforcement ratio. The wear
losses decreased depending on the increase in sintering temperature and
time. With the increase in the GNP reinforcement ratio, reductions in wear
losses were recorded. It has been concluded that the GNP reinforcement
element in the composite structure reduces the friction coefficient and wear
losses by having some lubricating effect. It was observed that the neck and
bonding formation between Al 99.9 matrix grains improved with increasing
sintering temperature and time. It was concluded that with the development
of intergranular bonds, the porosity in the composite structure decreased
and the mechanical properties increased. |
