Resumo: | ANVISA made changes to its regulations, setting new values for the fatigue tests, increasing the number of cycles that prostheses must endure without presenting failures. The standard used is ABNT NBR 7206-6:2013, in which all prostheses being commercialized must be tested in the new parameters. In this article, studies were conducted based on the requirement to revalidate the Co-26Cr-6Mo metallic alloy (ASTM F75). Microstructural characterizations (Optical and Scanning Electron Microscopies), and fatigue tests were carried out, with the aim of obtaining the mechanical behavior and features of the materials used in hip prostheses and comparing them with the standard. The grain size and inclusion contents were found to be controlled. Likewise, the prosthesis has withstand 10,000,000 cycles, and has not shown cracks, nor plastic deformations, enabling the biomedical use of this alloy according to the new regulations. Tensile test and liquid penetrant inspection were also carried out to take the parameters of the related physical properties. In the analysis with strain gauges, it was possible to detect the purely elastic deformation that occurred with the application of the load during fatigue tests, resulting in a slight variation of stress in the data acquisition system. |

La norma utilizada es la ABNT NBR 7206-6: 2013, en la que todas las prótesis que se comercializan deben ser probadas en los nuevos parámetros. En este artículo se realizaron estudios en base al requisito de revalidar la aleación metálica Co-26Cr-6Mo (ASTM F75). Se realizaron caracterizaciones microestructurales (Microscopía Óptica y Electrónica de Barrido), y ensayos de fatiga, con el objetivo de obtener el comportamiento mecánico y las características de los materiales utilizados en las prótesis de cadera y compararlos con el estándar. Se encontró que el tamaño de grano y los contenidos de inclusión estaban controlados. Asimismo, la prótesis ha resistido 10.000.000 de ciclos, y no ha presentado grietas, ni deformaciones plásticas, lo que permite el uso biomédico de esta aleación de acuerdo con la nueva normativa. También se realizaron pruebas de tracción e inspección por líquidos penetrantes para tomar los parámetros de las propiedades físicas relacionadas. En el análisis con galgas extensiométricas se pudo detectar la deformación puramente elástica que se presentaba con la aplicación de la carga durante los ensayos de fatiga, resultando en una ligera variación de esfuerzos en el sistema de adquisición de datos.A ANVISA realizou alterações em sua regulamentação, estabelecendo novos valores para os ensaios de fadiga, aumentando o número de ciclos que as próteses devem suportar sem apresentar falhas. A norma utilizada é a ABNT NBR 7206-6:2013, na qual todas as próteses que estão sendo comercializadas devem ser testadas nos novos parâmetros. Neste artigo, foram realizados estudos com base na exigência de revalidação da liga metálica Co-26Cr-6Mo (ASTM F75). Foram realizadas caracterizações microestruturais (Microscopias Óptica e Eletrônica de Varredura) e ensaios de fadiga, com o objetivo de obter o comportamento mecânico e as características dos materiais utilizados nas próteses de quadril e compare-los com a norma. O tamanho de grão e os teores de inclusão foram controlados. Da mesa forma, as próteses resistiram a 10.000.000 de ciclos, e não apresentando trincas, nem deformações plásticas, possibilitando o uso biomédico desta liga de acordo com as novas regulamentações. Os ensaios de tração e o ensaio de líquido penetrante também foram realizados para obtenção dos parâmetros das propriedades físicas relacionadas. Na análise com extensômetros foi possível detector a deformação puramente elástica que ocorreu com a aplicação da carga durante os ensaios de fadiga, resultando em uma pequena variação de tensão no sistema de aquisição de dados.Research, Society and Development2022-03-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2785410.33448/rsd-v11i4.27854Research, Society and Development; Vol. 11 No. 4; e52011427854Research, Society and Development; Vol. 11 Núm. 4; e52011427854Research, Society and Development; v. 11 n. 4; e520114278542525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/27854/24158Copyright (c) 2022 Caique Movio Pereira de Souza; Raul Gaspari Santos ; Renato Chaves Souza; Vanderlei Araujo Militão ; Isaias Gouveia Silva; Vanessa Seriacopi; Wilson Carlos da Silva Juniorhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSouza, Caique Movio Pereira deSantos , Raul Gaspari Souza, Renato Chaves Militão , Vanderlei Araujo Silva, Isaias Gouveia Seriacopi, Vanessa Silva Junior, Wilson Carlos da 2022-03-27T17:17:09Zoai:ojs.pkp.sfu.ca:article/27854Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:45:27.296117Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
