Caracterización microestructural de recubrimientos NiCoCrAlYTa obtenidos por láser coaxial y por refusión láser sobre AISI 316L

Pereira Falcón, Juan Carlos; Candel Bou, Juan José; Amado, J.M.; Amigó Borrás, Vicente (Sistema de Revistas de la Universidad de Antioquia, 2014)

[ES] En este estudio se ha evaluado la microestructura de recubrimientos NiCoCrAlYTa depositados mediante la técnica de laser cladding coaxial, y en recubrimientos obtenidos por proyección térmica de alta velocidad (HVOF) ...
Desarrollo y caracterización de recubrimientos MCrAlY obtenidos mediante técnicas láser para aplicaciones de barrera térmica en aceros inoxidables

Pereira Falcón, Juan Carlos (Universitat Politècnica de València, 2015-07-10)

[EN] The coaxial laser cladding process is an excellent tool to obtain quality coatings, achieving complete melting and deposition of alloys with high melting point on complex 3D surfaces. In this work we have studied the ...
Electrochemical corrosion behavior and mechanical properties of Ti-Ag biomedical alloys obtained by two powder metallurgy processing routes

Zambrano Carrullo, J. C.; Dalmau-Borrás, Alba; Amigó, Vicente; Navarro-Laboulais, J.; Pereira Falcón, C. (Elsevier, 2020-12)

[EN] Titanium is frequently used as a biomaterial and the importance of Ti-Ag alloys has increased thanks to the antibacterial behavior of silver. In this study, Ti-Ag alloys (5, 10 and 15 wt% Ag) were obtained by two ...
Evaluación de la anisotropía en las propiedades mecánicas del acero inoxidable AISI 304 laminado en frío

Pereira Falcón, Juan Carlos; Torres, Mary; Amigó Borrás, Vicente; Zambrano Carrullo, Jenny Cecilia (Universidad de Carabobo, Facultad de Ingeniería, 2012)

[EN] The anisotropy is the term used in metallic materials to describe the difference between the mechanical properties according to the direction in which they were evaluated. In this study we determined the variation of ...
Influence of process parameters and initial microstructure on the oxidation resistance of Ti48Al2Cr2Nb coating obtained by laser metal deposition

Zambrano Carrullo, Jenny Cecilia; Pereira Falcón, Juan Carlos; Amigó, Vicente (Elsevier, 2019)

[EN] Ti6Al4V have been the most important and versatile titanium alloys currently used, due to their excellent combination of low density and good mechanical properties, despite their application temperature being limited ...
Laser Cladding of MCrAlY coatings on stainless steel

Tobar, M.J.; Amado, J.M.; Yáñez, A.; Pereira Falcón, Juan Carlos; Amigó Borrás, Vicente (Elsevier, 2014)

MCrAlY alloys (where M stands for Ni,Co or both) are commonly used as overlay protective coatings in gas turbine engine components against high temperature oxidation and corrosion. The protective effect of these alloys is ...
Mechanical and microstructural characterization of MCrAlY coatings produced by laser cladding: The influence of the Ni, Co and Al content

Pereira, J. C.; Zambrano, J. C.; Rayón, E.; Yañez, A.; Amigó, Vicente (Elsevier, 2018-03-25)

[EN] Laser metal deposition (LMD) and laser cladding (LC) are alternative methods to thermal spraying processes to produce dense, high-quality coatings. In this work, two MCrAlY coatings (M=Ni+Co) have been prepared onto ...
Microstructure and mechanical properties of NiCoCrAlYTa alloy processed by press and sintering route

Pereira Falcón, Juan Carlos; ZAMBRANO CARRULLO, JENNY CECILIA; Afonso, Conrado Ramos Moreira; Amigó Borrás, Vicente (Elsevier, 2015-03)

Nickel-based superalloys such as NiCoCrAlY are widely used in high-temperature applications, such as gas turbine components in the energy and aerospace industries, due to their strength, high elastic modulus, and ...
