An assessment of biomedical CoCrMo alloy fabricated by direct metal laser sinte...
Girão, Daniel de Castro; Béreš, Miloslav; Jardini, André Luiz; Maciel Filho, Rubens; Silva, Cleiton Carvalho; Siervo, Abner deCoCrMo alloys have been used for several decades in implantable devices due to their favourable mechanical properties, low wear rate in addition to good biocompatibility and high corrosion resistance. These alloys are conventionally produced via casting and/or forging route, however additive manufacturing techniques being recently employed in their fabrication. In this work, CoCrMo samples were produced by dire...
Deformation-induced martensitic transformation in Co-28Cr-6Mo alloy produced by...
Antunes, Luiz Henrique Martinez; Quintero, John Jairo Hoyos; Andrade, Tathiane Caminha; Sarvezuk, Paulo Willian Carvalho; Wu, Leonardo; Ávila, J.A.The wear resistance of the biomedical low-carbon Co-28Cr-6Mo (wt.-%) alloy is primarily determined by the onset and magnitude of the face-centered cubic to hexagonal close-packed deformation-induced martensitic phase transformation. In metal-on-metal joint bearings, local plastic deformation occurs on the surface and in the subsurface regions. This can cause deformation-assisted structural changes in the materi...
Mechanical and phase transformation behaviour of biomedical Co-Cr-Mo alloy fabr...
Béreš, Miloslav; Silva, C.C.; Sarvezuk, Paulo Willian Carvalho; Wu, Leonardo; Antunes, Luiz Henrique Martinez; Jardini, André LuizBiomedical cobalt-chromium-molybdenum (Co-Cr-Mo) alloys have been used in the cast or wrought form as prosthetic implant materials for more than five decades. Recently, additive manufacturing techniques are employed to produce parts directly from metal precursor powder with a composition suitable for biomedical applications. In the work present, we examine both mechanical behaviour and γ→ε phase transformation ...
Osseointegration improvement of Co-Cr-Mo alloy produced by additive manufacturing
Iatecola, Amilton; Longhitano, Guilherme Arthur; Antunes, Luiz Henrique Martinez; Jardini, André Luiz; Miguel, Emilio de Castro; Béreš, MiloslavCobalt-base alloys (Co-Cr-Mo) are widely employed in dentistry and orthopedic implants due to their biocompatibility, high mechanical strength and wear resistance. The osseointegration of implants can be improved by surface modification techniques. However, complex geometries obtained by additive manufacturing (AM) limits the efficiency of mechanical-based surface modification techniques. Therefore, plasma imme...

Pereira Rodrigues, Isabella Caroline; Tamborlin, Leticia [UNESP]; Rodrigues, Ana Amélia; Jardini, André Luiz; Ducati Luchessi, Augusto [UNESP]Made available in DSpace on 2022-04-28T19:27:45Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-03-15; Polymeric membranes have gained popularity as fibrous structures for tissue regeneration. This research focuses on the rotary jet spinning (RJS) process combined with a polymer as a strategy for designing membranes. To this end, RJS-polyurethane (RJS-PU) membranes with different microstructures were pro...
