Effect of Alloying Elements on Laser Surface Modification of Powder Metallurgy to Improve Surface Mechanical Properties of Beta Titanium Alloys for Biomedical Application
Rossi, M. C.; Amado, José; Tobar, M. J.; Vicente-Escuder, Ángel; Yáñez, A.; Amigó, Vicente (Elsevier, 2021-09)[Abstract] Beta-type titanium alloy surfaces (Tie35Nbe10Ta (TNT) and Tie30Nbe4Sn (TNS)) weremodified by laser using a power of 1000 W and speed of 6.7 mm/s (Condition A) and a powerof 1500 W with speed of 10 mm/s (Condition ... -
Influence of Femtosecond Laser Modification on Biomechanical and Biofunctional Behavior of Porous Titanium Substrates
Beltrán, Ana M.; Giner, Mercè; Rodríguez, Ángel; Trueba Muñoz, Paloma; Rodríguez-Albelo, Luisa Marleny; Vázquez-Gámez, MA; Godinho, Vanda; Alcudia, Ana; Amado, José; López-Santos, Carmen; Torres, Yadir (MDPI, 2022-04-19)[Abstract] Bone resorption and inadequate osseointegration are considered the main problems of titanium implants. In this investigation, the texture and surface roughness of porous titanium samples obtained by the space ... -
Laser Surface Modification in Ti-xNb-yMo Alloys Prepared by Powder Metallurgy
Tendero, Inmaculada; Rossi, Mariana; Viera, Mauricio; Amado, José; Tobar, M.J.; Vicente-Escuder, Ángel; Yáñez, Armando; Amigó, Vicente (MDPI, 2021-02)[Abstract] The main objective was to study the effect of surface modification by laser on Ti-Nb-Mo powder metallurgical alloys to improve their mechano-chemical behavior and their application as a biomedical implant. The ... -
Surface Modification of Porous Titanium Discs Using Femtosecond Laser Structuring
Trueba Muñoz, Paloma; Amado, José; Rodríguez, Ángel; Tobar, M.J.; Giner, Mercé; Amigó, Vicente; Torres, Yadir (MDPI, 2020-06)[Abstract] The failure of titanium implants is associated with two main problems that include the bone resorption and fracture of the surrounding bone tissue (stiffness incompatibility) and implant loosening (poor ... -
Tribo-Mechanical and Cellular Behavior of Superficially Modified Porous Titanium Samples Using Femtosecond Laser
Trueba Muñoz, Paloma; Giner, Mercè; Rodríguez Carballo, Ángel; Beltrán, Ana M.; Amado, José; Montoya-García, María José; Rodríguez-Albelo, Luisa Marleny; Torres, Yadir (ScienceDirect, 2021-09)[Abstract] In this work, the surface of porous titanium samples obtained by the space-holder technique was treated with a femtosecond laser to improve their osseointegration. Instrumented micro-indentation and scratch test ...
