Resumo: Titanium is an example of biomaterial used in orthopedic and orthodontic implants, because it has good corrosion resistance and excellent biocompatibility. Thus, studies seek to obtain a titanium coating to improve the adhesion between the bone and the implant, by modifying the metal surface. The objective of this work was to study the corrosive effect using as means the synthetic saliva and the 1.5 SBF (Simulated Body Fuid), in addition to studying the bactericidal effect of the apatite layer on the silver nanoparticle and the essential oil formed on the surface of the titanium. The coating with hydroxyapatite was performed by the biomimetic method. After the immersion, some samples were submitted to the solution of silver nanoparticle and other/s in essential oil of lemongrass. By the scanning electron microscopy of the Ti c.p. With addition of silver, it is possible to observe the formation of homogeneous layers of small compacted globules. From the corrosion test it was possible to observe that in that in the medium of 1.5 FBS, as well as in synthetic saliva, coating with hydroxyapatite and silver nanoparticle bactericides and lemongrass oil improved the corrosive properties of the sample.

Assim, estudos procuram obter um recobrimento no titânio visando melhorar a adesão entre o osso e o implante, através da modificação da superfície do metal. O objetivo do trabalho foi estudar a caracterização das superfícies do Ti c.p com o recobrimento, o efeito corrosivo utilizando como meios a saliva sintética e o 1,5 SBF (Simulated Body Fuid), além de estudar o efeito bactericida da camada de apatita junto a nanopartícula de prata e o óleo essencial formados sobre a superfície do titânio. O recobrimento com hidroxiapatita foi realizado pelo método biomimético. Após a imersão, algumas amostras foram submetidas à solução de nanopartícula de prata e outras em óleo essencial de capim limão. Através da microscopia eletrônica de varredura do Ti c.p com adição de nanopartícula de prata, pode-se observar a formação de camadas homogêneas de pequenos glóbulos compactados e com adição de óleo a formação de camadas heterogêneas. Pelo ensaio de corrosão foi possível observar que tanto no meio de 1,5 SBF, quanto no meio de saliva sintética, o recobrimento com hidroxiapatita e com os bactericidas nanopartícula de prata e óleo capim-limão melhoraram as propriedades corrosivas da amostra.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPESapplication/pdfporUniversidade Federal de AlfenasPrograma de Pós-Graduação em Ciência e Engenharia de MateriaisUNIFAL-MGBrasilInstituto de Ciência e Tecnologiainfo:eu-repo/semantics/openAccesshttp://creativecommons.org/licenses/by-nc-nd/4.0/TitânioPrataNanopartículasHidroxiapatitaBactericidasENGENHARIA DE MATERIAIS E METALURGICA::METALURGIA FISICAEstudo do comportamento do titânio recoberto com apatita e dopado com nanopartícula de prata e óleo essencialStudy of the behavior of apatite coated titanium and doped with silver nanoparticle and essential oilinfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/publishedVersion-429741725949863893160060060081349704314190697772075167498588264571reponame:Repositório Institucional da Universidade Federal de Alfenas - RiUnifalinstname:Universidade Federal de Alfenas (UNIFAL)instacron:UNIFALPrado, Deborah GouvêaLICENSElicense.txtlicense.txttext/plain;
