Resumo: | The objective of this work is to evaluate the influence of the addition of different concentrations of particulate reinforcement in the production of commercially pure aluminum composites reinforced with blast-furnace slag via powder metallurgy. The processing of these materials was done by sieving, mixing and compacting powders of reinforced aluminum with 5, 10 and 15% of blast-furnace slag. The cold uniaxial compaction was realized at a pressure of 430 MPa. The obtained materials were sintered at 610°C for 2h under inert atmosphere. Unreinforced aluminum samples were also produced. The characterization of the materials was realized by density and microhardness measurements and wear tests. The morphological analysis was realized by scanning electron microscopy. As results, the materials had a relative density greater than 93,8%, reaching 98,6% for pure aluminum. The composites showed a homogeneous distribution of reinforcement particles and progressive improvement in microhardness with increasing slag concentration. However, regarding wear resistance, the result was the opposite. This result suggests that the reinforcing particles, being made of ceramic material, may have worked as an abrasive when released from the aluminum matrix, since commercially pure aluminum is extremely malleable and cannot hold the slag particles. |

O processamento desses materiais foi feito peneirando, misturando e compactando pós de alumínio reforçado com 5, 10 e 15% de escória de alto-forno. A compactação uniaxial a frio foi realizada a uma pressão de 430 MPa. Os materiais obtidos foram sinterizados a 610°C por 2h sob atmosfera inerte. Amostras de alumínio não reforçadas também foram produzidas. A caracterização dos materiais foi realizada por meio de medições de densidade e microdureza e ensaios de desgaste. A análise morfológica foi realizada por microscopia eletrônica de varredura. Como resultados, os materiais apresentaram densidade relativa superior a 93,8%, chegando a 98,6% para o alumínio puro. Os compósitos apresentaram distribuição homogênea das partículas de reforço e melhoria progressiva da microdureza com o aumento da concentração de escória. Porém, em relação à resistência ao desgaste, o resultado foi o oposto. Este resultado sugere que as partículas de reforço, por serem feitas de material cerâmico, podem ter funcionado como abrasivo quando liberadas da matriz de alumínio, uma vez que o alumínio comercialmente puro é extremamente maleável e não consegue reter as partículas de escória.Universidade Federal de Viçosa - UFV2023-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1746810.18540/jcecvl9iss12pp17468The Journal of Engineering and Exact Sciences; Vol. 9 No. 12 (2023); 17468The Journal of Engineering and Exact Sciences; Vol. 9 Núm. 12 (2023); 17468The Journal of Engineering and Exact Sciences; v. 9 n. 12 (2023); 174682527-1075reponame:Revista de Engenharia Química e Químicainstname:Universidade Federal de Viçosa (UFV)instacron:UFVenghttps://periodicos.ufv.br/jcec/article/view/17468/9389Copyright (c) 2023 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilva, Igor Carvalho daDias, Abraão PereiraGalárraga, Edison Gustavo CuevaLima, Emmanuel Pacheco Rocha2024-03-26T17:17:46Zoai:ojs.periodicos.ufv.br:article/17468Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/indexONGhttps://periodicos.ufv.br/jcec/oaijcec.journal@ufv.br||req2@ufv.br2446-94162446-9416opendoar:2024-03-26T17:17:46Revista de Engenharia Química e Química - Universidade Federal de Viçosa (UFV)false |
