Una de estas áreas de investigación es el uso de recubrimientos de materiales mediante aleaciones de alta entropía. Una aleación de alta entropía es aquella que está compuesta por cinco o más elementos en una composición aproximadamente equiatómica y tiene una entropía configuracional mayor o igual a 1.5R, donde R es la constante universal de los gases. En este trabajo, mediante la modalidad de colaboración científica, el Instituto Tecnológico de Karlsruhe - KIT de Alemania, realizó el proceso de deposición de los recubrimientos multicomponentes de aleación de alta entropía de CrNbMoTaW en el sustrato acero 316L con la técnica sputtering. El objetivo principal de este estudio fue investigar la resistencia a la corrosión, la composición química y otras propiedades del recubrimiento HEA variando el flujo de Ar y presión de trabajo en la deposición de la película nanoestructurada. Para los recubrimientos se utilizaron blancos de 99.99% de pureza con una distancia entre estos y el sustrato de 300mm ± 5. La microestructura de los recubrimientos se analizó mediante AFM (microscopia de fuerza atómica), SEM (microscopia electrónica de barrido), XRD (difracción de rayos X), XPS (espectroscopía de fotoemisión de rayos X), EDS (espectroscopía de energía dispersada) e interferometría. Se determinó el comportamiento de la resistencia a la corrosión mediante las técnicas de Velocidad de corrosión con la técnica Polarización Potenciodinámica Tafel y Espectroscopia de Impedancia Electroquímica (EIS), adicionalmente, para evaluar la dureza de los recubrimientos HEAs se realizaron analisis de dureza mediante pruebas de nanoindentación con punta de diamante Berkovich. Durante la investigación, se obtiene recubrimientos en conformidad a los requisitos de HEA, así mismo se lograron obtener comportamientos aproximados de resistencia a la corrosión del acero inoxidable 316L.

One of these research areas is the use of high-entropy alloys material coatings. A high-entropy alloy is one that is composed of five or more elements in approximately equiatomic composition and has a configurational entropy greater than or equal to 1.5R, where R is the universal gas constant. In this work, the Karlsruhe Institute of Technology - KIT of Germany, carried out the deposition process of high-entropy alloy CrNbMoTaW multicomponent coatings on the 316L steel substrate using the sputtering technique in a scientific collaboration. The main objective of this study was to investigate the corrosion resistance, chemical composition, and other properties of the HEA coating by varying the Ar flow and working pressure in the deposition of the nanostructured film. For the coatings, 99.99% pure targets were used with a distance between these and the substrate of 300mm ± 5. The microstructure of the coatings was analyzed by AFM (atomic force microscopy), SEM (scanning electron microscopy), XRD (X-ray diffraction), XPS (X-ray photoelectron spectroscopy), EDS (energy-dispersive spectroscopy), and interferometry. The behavior of the corrosion resistance was determined by the Electrochemical Impedance Spectroscopy (EIS) and Corrosion Rate techniques using Tafel Potentiodynamic Polarization, additionally, to evaluate the hardness of the HEA coatings, nanoindentation tests were performed using a Berkovich diamond tip. During the investigation, the coatings were found to conform to the HEA requirements, and approximate behaviors of corrosion resistance of stainless steel 316L were achieved.MaestríaMagíster en Ingeniería - Materiales y ProcesosIngeniería de superficiesxx, 103 páginasapplication/pdfspaUniversidad Nacional de ColombiaBogotá - Ingeniería - Maestría en Ingeniería - Materiales y ProcesosFacultad de IngenieríaBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá620 - Ingeniería y operaciones afines::629 - Otras ramas de la ingenieríaAleación de alta entropíaSputteringCorrosiónHEAsAnticorrosivasHigh entropy alloySputteringCorrosionHEAsAnticorrosiveMateriales de construcciónTecnología de materialesEnsayo de materialesBuilding materialsMaterials engineeringMaterials testingCaracterización de la resistencia a la corrosión de aleaciones multicomponentes de CrNbMoTaW de alta entropía depositados con la técnica de sputteringCharacterization of the corrosion resistance of high entropy multi- component CrNiMoTaW alloys deposited using the sputtering techniqueTrabajo de grado - Maestríainfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/acceptedVersionTexthttp://purl.org/redcol/resource_type/TMFundación Universa, “Más de 26 mil millones de pesos pierde la industria colombiana debido a la corrosión de materiales.” [Online].
