Resumo

APERADOR, W.; LIZARAZO, S.  e  MEJIA, A.. Biomaterials based in fermanal steel, an option to the surgical implants manufacturing. Rev. Mex. Ing. Quím [online]. 2013, vol.12, n.2, pp.337-344. ISSN 1665-2738.

We evaluate the potential use of Fermanal alloy (Fe-Al-Mn) in the manufacture of surgical implants. For this, the steel of that iystem is subjected to heat treatment in order to find the suitable corrosion resistance. The electrochemical behavior was evaluated by electrochemical impedance spectroscopy techniques and potentiodynamic polarization curves using Hanks balanced salt solution as electrolyte. Microstructural characterization was performed through scanning electron microscopy (SEM) and the corrosion products were evaluated by X-ray diffraction (XRD). It was found that the heat treatment improves the electrochemicat properties of the steel Fe-Al-Mn, whence this alloy is presented as an alternative to the currently alloys used in the field of biomaterials, such as stainless steel type AISI 316LVM.

Palavras-chave : biomaterials; FeMnAl; corrosion; heat treatment.
