Resumo: | An anticorrosive coating of post-consumer polyethylene terephthalate (PET) was applied on carbon steel by using an industrial press. The PET layer showed a good adhesion on the substrate, evaluated by using a pull off test, when compared with the traditional organic coatings. In addition, scanning electron microscopy (SEM) analysis showed that the PET layer was uniform, homogeneous, and free of cracks or defects. The Fourier-transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC) proved that the PET properties were not affected by the deposition process. The PET organic coating is a promising coating, due to its corrosion resistance evaluated by using salt spray tests, even though the applied thickness of 65 µm was considered thin for a high-performance coating. The electrochemical impedance spectroscopy (EIS) showed that the PET coating has a capacitive effect and its electrochemical behavior was not affected as the exposure time increased, resulting in an impedance modulus value of 1010 Ω·cm2, after 576 h of immersion in an aqueous solution of NaCl 3.0 wt %. |

A camada de PET apresentou boa adesão ao substrato, avaliada pelo teste de arrancamento, quando comparada com os revestimentos orgânicos tradicionais. Além disso, a análise por microscopia eletrônica de varredura (MEV) mostrou que a camada de PET era uniforme, homogênea e livre de rachaduras ou defeitos. A espectroscopia de infravermelho com transformada de Fourier (FTIR) e a calorimetria exploratória diferencial (DSC) provaram que as propriedades do PET não foram afetadas pelo processo de deposição. O revestimento orgânico PET é um revestimento promissor, devido à sua resistência à corrosão avaliada por testes de névoa salina, embora a espessura aplicada de 65 µm tenha sido considerada fina para um revestimento de alto desempenho. A espectroscopia de impedância eletroquímica (EIS) mostrou que o revestimento de PET tem efeito capacitivo e seu comportamento eletroquímico não foi afetado com o aumento do tempo de exposição, resultando em um valor de módulo de impedância de 1010 Ω·cm2, após 576 h de imersão em solução aquosa de NaCl 3,0% em peso.CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorengUniversidade Federal de Minas GeraisUFMGBrasilENG - DEPARTAMENTO DE ENGENHARIA QUÍMICACoatingsRevestimentosRevestimento plásticoAço-carbono - CorrosãoCorrosionOrganic coatingsCarbon steelEISElectrochemical impedance spectroscopyPETPolyethylene terephthalateProperties of post-consumer polyethylene terephthalate coating mechanically deposited on mild steelsPropriedades do revestimento de tereftalato de polietileno pós-consumo depositado mecanicamente sobre aços maciosinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.mdpi.com/2079-6412/9/1/28Elisângela Aparecida da SilvaMichele FedelFlavio DeflorianFernando CottingVanessa de Freitas Cunha Linsapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain;
