Resumo: Metallic biomaterials in the oral cavity exposed to extreme conditions that affect it and reduce its biofunctionality. Surface modification by plasma spray oxide deposition is one of the methods used as an alternative to improve the bioactivity of Ti alloy implants. The objective of this work was to study the physicochemical surface characteristics of Ti-6Al-4V and Ti-6Al-7Nb alloys modified by TiO2 coating via plasma spray and thermochemical treatment with NaOH. The Ti-6Al-4V and Ti-6Al-7Nb alloys obtained in a cylindrical shape, sectioned in the longitudinal direction, and sectioned with dimensions of 20 mm in diameter and 2 mm in thickness, sanded and polished. The microstructure revealed using Kroll's solution. Then, titanium oxide (TiO2) powder deposition performed on Ti-6Al-4V and Ti-6Al-7Nb samples and submitted to thermochemical treatment with NaOH solution. The physical-chemical characterizations and elemental analysis performed using argon-induced plasma emission spectrometry (ICP), X-ray fluorescein spectrometry (XRF), scanning electron microscopy (SEM), X-ray diffraction (XRD). The results showed a rough and porous TiO2 coating morphology. TiO2 deposition resulted in an apparent mixture of stoichiometric and non-stoichiometric oxides on the substrate surface, in addition to presenting an optimization in the substrate/coating interaction with the NaOH treatment, leading to an increase in the surface area. It seen that the TiO2/Ti-6Al-4V/ and TiO2/Ti-6Al-7Nb systems present good chemical adhesion between substrate and coating, and the layer formed by the TiO2 coating associated with the treatment with NaOH presents a relevant level of porosity, being an important feature for osseointegration.

La modificación de la superficie mediante la deposición de óxido por pulverización de plasma es uno de los métodos utilizados como alternativa para mejorar la bioactividad de los implantes de aleación de Ti. El objetivo de este trabajo fue estudiar las características fisicoquímicas superficiales de las aleaciones Ti-6Al-4V y Ti-6Al-7Nb modificadas por recubrimiento de TiO2 vía plasma spray y tratamiento termoquímico con NaOH. Las aleaciones Ti-6Al-4V y Ti-6Al-7Nb obtenidas en forma cilíndrica, seccionadas en sentido longitudinal, y seccionadas con dimensiones de 20 mm de diámetro y 2 mm de espesor, lijadas y pulidas. La microestructura revelada utilizando la solución de Kroll. Luego, se realizó la deposición de polvo de óxido de titanio (TiO2) en muestras de Ti-6Al-4V y Ti-6Al-7Nb y se sometieron a tratamiento termoquímico con solución de NaOH. Las caracterizaciones físico-químicas y el análisis elemental se realizaron mediante espectrometría de emisión de plasma inducida por argón (ICP), espectrometría de fluoresceína de rayos X (XRF), microscopía electrónica de barrido (SEM), difracción de rayos X (XRD). Los resultados mostraron una morfología de recubrimiento de TiO2 rugosa y porosa. La deposición de TiO2 resultó en una aparente mezcla de óxidos estequiométricos y no estequiométricos en la superficie del sustrato, además de presentar una optimización en la interacción sustrato/revestimiento con el tratamiento con NaOH, lo que llevó a un aumento en el área superficial. Se observó que los sistemas TiO2/Ti-6Al-4V/ y TiO2/Ti-6Al-7Nb presentan buena adherencia química entre sustrato y recubrimiento, y la capa formada por el recubrimiento de TiO2 asociado al tratamiento con NaOH presenta un nivel de porosidad relevante, siendo una característica importante para la osteointegración.Biomateriais metálicos na cavidade oral expostos a condições extremas que a afetam e reduzem sua biofuncionalidade. A modificação da superfície por deposição de óxido por plasma spray é um dos métodos utilizados como alternativa para melhorar a bioatividade de implantes de ligas de Ti. O objetivo deste trabalho foi estudar as características físico-químicas superficiais das ligas Ti-6Al-4V e Ti-6Al-7Nb modificadas por revestimento de TiO2 via plasma spray e tratamento termoquímico com NaOH. As ligas Ti-6Al-4V e Ti-6Al-7Nb obtidas em forma cilíndrica, seccionadas no sentido longitudinal, e seccionadas com dimensões de 20 mm de diâmetro e 2 mm de espessura, lixadas e polidas. A microestrutura revelada usando a solução de Kroll. Em seguida, foi realizada a deposição de pó de óxido de titânio (TiO2) em amostras de Ti-6Al-4V e Ti-6Al-7Nb e submetidas a tratamento termoquímico com solução de NaOH. As caracterizações físico-químicas e análise elementar foram realizadas por meio de espectrometria de emissão de plasma induzido por argônio (ICP), espectrometria de fluoresceína de raios-X (XRF), microscopia eletrônica de varredura (MEV), difração de raios-X (DRX). Os resultados mostraram uma morfologia de revestimento de TiO2 rugoso e poroso. A deposição de TiO2 resultou em uma aparente mistura de óxidos estequiométricos e não estequiométricos na superfície do substrato, além de apresentar uma otimização na interação substrato/revestimento com o tratamento com NaOH, levando a um aumento da área superficial. Verificou-se que os sistemas TiO2/Ti-6Al-4V/ e TiO2/Ti-6Al-7Nb apresentam boa adesão química entre substrato e revestimento, e a camada formada pelo revestimento de TiO2 associado ao tratamento com NaOH apresenta um nível de porosidade relevante, sendo uma característica importante para a osseointegração.Research, Society and Development2022-06-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/30720Research, Society and Development; Vol. 11 No. 8; e34411830720Research, Society and Development; Vol. 11 Núm. 8; e34411830720Research, Society and Development; v. 11 n. 8; e344118307202525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/30720/26590Copyright (c) 2022 Ana Elisa Vilicev Italiano; Daniela Vieira Amantea; Luís Geraldo Vaz; Márcio Luiz dos Santoshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessItaliano, Ana Elisa Vilicev Amantea, Daniela VieiraVaz, Luís GeraldoSantos, Márcio Luiz dos2022-07-01T13:34:06Zoai:ojs.pkp.sfu.ca:article/30720Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:47:23.117522Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
