Abstract: This work has compared the surfaces of two different steel samples used as orthopedical implants, classified as ASTM F138 and ISO5832-9, through optical emission spectroscopy, by means of SEM and EDS. The samples (implants) were also submitted to potentiodynamic cyclic polarization in Ringer lactate and NaCl 0.9 M L-1 solutions; ISO5832-9 sample did not show any kind of localized corrosion, but in the case of F138 steel was observed a pit localized corrosion in both solutions. In Ringer lactate solution it was observed a loss of about 63% for nickel and 26% for iron for F138 stell, compared to the initial composition.
