Resumo: | Titanium and its alloys are used as biomaterials because their excellent combination of high corrosion resistance, low modulus of elasticity and biocompatibility. However, titanium and its alloys cannot meet all the clinical requirements. In this sense, in order to improve the electrochemical and bioactive properties, this thesis aims to evaluate the effect of the severe plastic deformation as well as the surface modification treatments on the corrosion resistance and bioactivity of titanium alloys (α' + β) and (β). The titanium alloys, Ti13Nb13Zr (α' + β) and Ti35Nb7Zr5Ta (β), were deformed by the high-pressure torsion (HPT) method. Afterward, surface modification treatments, such as the anodization and chemical treatments, were carried out both in samples non-deformed and deformed by HPT. Finally, corrosion and bioactivity tests were performed in simulated body fluid (SBF). The tests were performed on samples with treated surfaces compared with non-treated surfaces in the deformed and undeformed conditions. The samples’ microstructures were analyzed by confocal laser microscopy (CLM), scanning electron microscopy (SEM) and X-ray diffraction (XRD). Hardness tests were also performed after the HPT process. On the other hand, surface modification treatments, and the formation of apatite in bioactivity assays were evaluated by scanning electron microscopy (SEM), with chemical analyzes carried out by dispersive energy spectroscopy (EDS) and phase identification by X-ray diffraction (XRD). In general, the corrosion resistance of the titanium alloys improved with the anodization treatment. Apatite deposits were observed on Ti13Nb13Zr alloy samples, in the conditions non-deformed and deformed by HPT. The Ti35Nb7Zr5Ta appears to have a lower apatite-formation ability compared to Ti13Nb13Zr. |

Cependant, le titane et ses alliages ne peuvent pas répondre à toutes les exigences cliniques. En ce sens, afin d’améliorer les propriétés électrochimiques et bioactives, cette thèse vise à évaluer l’effet de la déformation plastique sévère ainsi que des traitements de modification de surface sur la résistance à la corrosion et la bioactivité des alliages de titane (α '+ β) et (β). Les alliages Ti13Nb13Zr (α' + β) et Ti35Nb7Zr5Ta (β) ont été déformés par la méthode de torsion à haute pression (HPT-High Pressure torsion). Ensuite, des traitements de modification de surface, tels que l’anodisation et les traitements chimiques, ont été effectués dans des échantillons non déformés et déformés par HPT. Enfin, des tests de corrosion et de bioactivité ont été réalisés dans un fluide corporel simulé (SBF). Les tests ont été effectués sur des échantillons de surfaces traitées par rapport à des surfaces non traitées de conditions déformées et non déformées. La microstructure des échantillons a été analysée par microscope confocal à balayage laser (CLM), microscopie électronique à balayage (SEM) et diffraction des rayons X (XRD). Des tests de dureté sont également effectués après le processus HPT. D'autre part, les traitements de modification de surface et la formation d'apatite dans les tests de bioactivité sont évalués par SEM, analyses chimiques par spectroscopie d'énergie dispersive (EDS) et DRX. En général, la résistance à la corrosion des alliages de titane évaluées, améliorée avec le traitement d'anodisation. Des dépôts d'apatite ont été observés sur des échantillons d'alliage Ti13Nb13Zr, non déformés et déformés par HPT, pour les traitements de modification de surface proposés. Le Ti35Nb7Zr5Ta semble avoir une capacité de formation d'apatite inférieure à celle du Ti13Nb13Zr.Titânio e suas ligas são utilizados como biomateriais devido à sua excelente combinação de alta resistência à corrosão, baixo módulo de elasticidade e biocompatibilidade. No entanto, o titânio e suas ligas não podem atender a todos os requisitos clínicos. Neste sentido, a fim de melhorar as propriedades eletroquímicas e bioativas, esta tese tem como objetivo avaliar o efeito da deformação plástica severa e os tratamentos de modificação de superfície na resistência à corrosão e bioatividade de ligas de titânio (α '+ β) e (β). As ligas de titânio, (α' + β) Ti13Nb13Zr e a liga (β) Ti35Nb7Zr5Ta foram deformadas pelo método de deformação plástica severa de torção sob alta pressão (HPT, High Pressure Torsion). Além disso, tratamentos de modificação de superfície são propostos, como anodização e tratamentos químicos em amostras deformadas por HPT e em amostras não deformadas. Finalmente, os testes de corrosão e bioatividade foram realizados em fluido corporal simulado (SBF). Os testes foram realizados em amostras de superfícies tratadas em comparação com superfícies não tratadas de condições deformadas e não deformadas. A microestrutura das amostras foi analisada por microscopia confocal laser (MCL), microscopia eletrônica de varredura (MEV) e difração de raios X (DRX). Testes de dureza também são realizados após o processo HPT. Por outro lado, tratamentos de modificação de superfície e a formação de apatita em ensaios de bioatividade são avaliados por MEV, análises químicas por espectroscopia de energia dispersiva (EDS) e DRX. Em geral, a resistência à corrosão das ligas de titânio avaliadas melhorou com o tratamento de anodização. Depósitos de apatita foram observados em amostras da liga Ti13Nb13Zr, não deformadas e deformadas por HPT, para todos os tratamentos de modificação de superfície propostos A liga Ti35Nb7Zr5Ta parece ter uma menor capacidade de formação de apatita que a liga de Ti13Nb13Zr.OutraCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)CAPES #88887.137755/2017-00engUniversidade Federal de São CarlosCâmpus São CarlosPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMUFSCarAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/info:eu-repo/semantics/openAccessLiga de titânioLiga Ti13Nb13ZrLiga Ti35Nb7Zr5TaDeformação plástica severaNanotubos de TiO2ApatitaResistência à corrosãoBioatividadeTitanium alloysTi13Nb13Zr alloyTi35Nb7Zr5Ta alloySevere plastic deformationTiO2 nanotubesApatiteCorrosion resistanceBioactivityENGENHARIAS::ENGENHARIA DE MATERIAIS E METALURGICAInfluence of surface treatments on corrosion resistance properties of ultrafine grained titanium alloys for biomedical applicationsInfluência dos tratamentos de superfície nas propriedades de resistência à corrosão de ligas de titânio de grão ultrafino para aplicações biomédicasInfluence de traitements de surface sur les propriétés de résistance à la corrosion d'alliages de titane à grains ultrafins pour des applications biomédicalesinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesis600600cb99e59b-1f96-42f5-b037-0d807337944dreponame:Repositório Institucional da UFSCARinstname:Universidade Federal de São Carlos (UFSCAR)instacron:UFSCARORIGINALDiego Alfonso Godoy Pérez - Tese.pdfDiego Alfonso Godoy Pérez - Tese.pdfTese de doutoradoapplication/pdf8395708https://repositorio.ufscar.br/bitstream/ufscar/12028/1/Diego%20Alfonso%20Godoy%20P%c3%a9rez%20-%20Tese.pdf021766f1f78eb38fb4126340100df0f7MD51BCO carta comprovante autoarquivamento.pdfBCO carta comprovante autoarquivamento.pdfCarta comprovante autoarquivamentoapplication/pdf301089https://repositorio.ufscar.br/bitstream/ufscar/12028/2/BCO%20carta%20comprovante%20autoarquivamento.pdf71de4ffc9a37b554f244310cc6a977d1MD52CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml; charset=utf-8811https://repositorio.ufscar.br/bitstream/ufscar/12028/3/license_rdfe39d27027a6cc9cb039ad269a5db8e34MD53TEXTDiego Alfonso Godoy Pérez - Tese.pdf.txtDiego Alfonso Godoy Pérez - Tese.pdf.txtExtracted texttext/plain463774https://repositorio.ufscar.br/bitstream/ufscar/12028/4/Diego%20Alfonso%20Godoy%20P%c3%a9rez%20-%20Tese.pdf.txt73f84e0cef3c877f9dd754c22ecb697dMD54BCO carta comprovante autoarquivamento.pdf.txtBCO carta comprovante autoarquivamento.pdf.txtExtracted texttext/plain1467https://repositorio.ufscar.br/bitstream/ufscar/12028/6/BCO%20carta%20comprovante%20autoarquivamento.pdf.txtefc4af6cd9851592e68a05b8b660f65eMD56THUMBNAILDiego Alfonso Godoy Pérez - Tese.pdf.jpgDiego Alfonso Godoy Pérez - Tese.pdf.jpgIM Thumbnailimage/jpeg7974https://repositorio.ufscar.br/bitstream/ufscar/12028/5/Diego%20Alfonso%20Godoy%20P%c3%a9rez%20-%20Tese.pdf.jpg12482f04508422cad6dd03f78868bdd3MD55BCO carta comprovante autoarquivamento.pdf.jpgBCO carta comprovante autoarquivamento.pdf.jpgIM Thumbnailimage/jpeg10043https://repositorio.ufscar.br/bitstream/ufscar/12028/7/BCO%20carta%20comprovante%20autoarquivamento.pdf.jpgbbf1bb800953e998ea248581ddc8dff3MD57ufscar/120282023-09-18 18:31:46.112oai:repositorio.ufscar.br:ufscar/12028Repositório InstitucionalPUBhttps://repositorio.ufscar.br/oai/requestopendoar:43222023-09-18T18:31:46Repositório Institucional da UFSCAR - Universidade Federal de São Carlos (UFSCAR)false |

In this sense, in order to improve the electrochemical and bioactive properties, this thesis aims to evaluate the effect of the severe plastic deformation as well as the surface modification treatments on the corrosion resistance and bioactivity of titanium alloys (α' + β) and (β). The titanium alloys, Ti13Nb13Zr (α' + β) and Ti35Nb7Zr5Ta (β), were deformed by the high-pressure torsion (HPT) method. Afterward, surface modification treatments, such as the anodization and chemical treatments, were carried out both in samples non-deformed and deformed by HPT. Finally, corrosion and bioactivity tests were performed in simulated body fluid (SBF). The tests were performed on samples with treated surfaces compared with non-treated surfaces in the deformed and undeformed conditions. The samples’ microstructures were analyzed by confocal laser microscopy (CLM), scanning electron microscopy (SEM) and X-ray diffraction (XRD).

In general, the corrosion resistance of the titanium alloys improved with the anodization treatment.
