Resumo: | Biomaterials are in constant development in several branches of science such as Medicine and Materials Engineering, due to the growing demand for materials that can help or replace parts of the human body. Among these reasons, the objective of this work was to study the mechanical and biological properties of bioceramic bodies of different mixtures containing hydroxyapatite, alumina and titania. Among these studied materials, specimens were analyzed at limiting concentrations of 40% by mass of hydroxyapatite, 60% of alumina and 30% of titania, submitted to different thermal cycles, to evaluate the responses of the materials to mechanical tests of resistance to compression and hardness, and bioactivity test. The use of hydroxyapatite was due to its composition containing calcium phosphate as well as the composition of the human body, it is a raw material with a high rate of biocompatibility, reducing the risk of rejection by the host organism, ideal for regeneration and bone repair. Alumina is a well-known bioceramic due to its high mechanical strength and emerging biological properties, mainly for bone replacement. Titania presents improved biological and mechanical properties when in the presence of other raw materials. Hydroxyapatite and titania presented limitations of their mechanical properties in relation to sintering temperatures above 1200°C, unlike alumina in which their mechanical properties increased at temperatures of 1250°C. The HAp-Al2O3-TiO2 composition demonstrates biological properties of bioactivity as they interact with the submerged medium without loss of mass. |

Dentre essas razões o objetivo desse trabalho foi estudar as propriedades mecânicas e biológicas de corpos biocerâmicos de diferentes misturas contendo hidroxiapatita, alumina e titânia. Dentre esses materiais estudos, foram analisados corpos de prova em concentrações limitantes de 40% em massa de hidroxiapatita, 60% de alumina e 30% de titânia, submetidos a ciclos térmicos diferentes, para avaliar as respostas dos materiais a ensaios mecânicos de resistência à compressão e dureza, e teste de bioatividade. A utilização da hidroxiapatita foi devido sua composição conter fosfato de cálcio assim como a composição do corpo humano, é uma matéria- prima com elevada taxa de biocompatibilidade, reduzindo o risco de rejeição pelo organismo hospedeiro, ideal para regeneração e reparo ósseo. A alumina é uma biocerâmica conhecida devido sua alta resistência mecânica e emergente propriedades biológicas, principalmente para substituição de ossos. A titânia apresenta propriedades biológicas e mecânicas aprimoradas quanto em presença de outras matérias-primas. A hidroxiapatita e titânia apresentaram limitações de suas propriedades mecânicas em relação a temperatura de sinterização superiores a 1200°C, diferente da alumina na qual suas propriedades mecânicas aumentaram em temperaturas de 1250°C. A composição HAp- Al2O3-TiO2 demonstra propriedades biológicas de bioatividade pois interagem com o meio submerso sem perda de massa.1NãoBrasilFT - Faculdade de TecnologiaManaus (AM)Engenharia de Materiais - Bacharelado - ManausAndrade, Jean Carlos Silvahttp://lattes.cnpq.br/3330175940424250Sales Júnior, José Carlos CaladoAmorim, Mateus Oliveira dehttps://orcid.org/0000-0002-6777-4276Caporazzo, Ana Carolina de Amorim2023-12-06T16:46:03Z2023-12-06T16:46:03Z2023-07-13info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/bachelorThesishttp://riu.ufam.edu.br/handle/prefix/7198porhttps://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFAMinstname:Universidade Federal do Amazonas (UFAM)instacron:UFAM2023-12-06T16:46:59Zoai:localhost:prefix/7198Repositório InstitucionalPUBhttp://riu.ufam.edu.br/oai/requestopendoar:2023-12-06T16:46:59Repositório Institucional da UFAM - Universidade Federal do Amazonas (UFAM)false |
