摘要

This work is dedicated to the study of the synthesis process of one metal matrix composite, which is composed by the Al–Ni system reinforced with graphene through a mecanosintesis and sintering process. The grinding times were used are 3 h at high energy, and 96 h at low energy, with a sintering temperature of 550 °C. The results showed that grinding allowed a large homogenous dispersion of the Al–Ni matrix reinforcing material in this way to allow a new Al–Ni. Graphene composite, The composite with the best performance, in terms of better mechanical properties, was obtained for the alloy: 99%Al0.9%NI0.1%G) at low energy with a temperature of 550 °C and the alloy (99%Al0. 96Ni0.04G) at high energy, which showed low porosity, uniformly distributed reinforcing material and a strong bond between graphene and the Al–Ni matrix. The results shown here was obtained from: DRX, Optical microscopy and Microhardness in Vickers scale.
