Deposição a plasma de revestimento solido-lubrificante utilizando técnica de cilindros catódicos em aço AISI1020. 2022. 18 f. Trabalho de Conclusão de Curso (Graduação em Engenharia Mecânica) - Centro de Tecnologia, Universidade Federal do Rio Grande do Norte, Natal, 2022.https://repositorio.ufrn.br/handle/123456789/50723The use of solid lubricating films makes it a great option for controlling wear and friction under certain operating conditions, in addition to not harming the environment. Thus, this work aims to carry out a study on plasma deposition with cathode cylinders of MoS2 thin films on AISI 1020 steel substrates. °C, 350 °C and 400 °C, all with argon-rich atmosphere. After the treatments, they were submitted to chemical analyzes by X-ray diffraction (XRD), in addition to calotest tribological test. It was possible to quantify the coating thickness using scanning electron microscopy (SEM). In general, the results were successful in the deposition of molybdenum disulfide in all samples treated at fluctuating potential, as it was possible to visualize in the XRD, since it indicated the presence of peaks referring to MoS2 and its compounds, in addition to a significant reduction in wear through the calotest.Attribution 3.0 Brazilhttp://creativecommons.org/licenses/by/3.0/br/Cilindros CatódicosCathode CylinderMoS2MoS2DesgasteWearbachelorThesis
