Estudio de la dureza en compuestos metálicos de aluminiografeno producidos por el método de pulvimetalurgia en concentraciones de 1, 2 y 3 % en peso de grafeno

Abstract

The main objective of the research was to determine if there is variation in the mechanical property of hardness in aluminum due to the addition of graphene to metallic compounds manufactured by the powder metallurgy process. For which four treatments were developed with three repetitions in each one, each one of them was worked with different concentrations, of 1, 2 and 3% by weight of graphene, and it was compared with a blank test, that is, a treatment without reinforcement material interaction. For the data and results processing, the analysis of variance was used, which provides the study of the effect of factors on the mean of a continuous variable through the processing of its variances. In addition, the investigation was supplemented with a multiple comparison analysis to find out if there are particular significant differences between the different population groups. Results were obtained where it is evidenced that there are significant differences between its means, being the treatment with the highest percentage of graphene (3%) which represented a 12.97% increase in the measured property of hardness with respect to pristine aluminum. It is concluded that the treatment with a higher percentage of graphene addition is the most appropriate to improve the hardness of aluminum. It is recommended to study the other properties of the compound to better characterize the material.
