Resumo
In this investigation, in vitro corrosion tests have been carried out in naturally aerated Hank's solution at
25 °C, to evaluate the corrosion resistance of a commercial sintered NdFeB magnet by immersion test and
electrochemical techniques. Generalized corrosion occurred and instrumental Neutron Activation Analysis (INAA) was
applied to analyze elements leached into Hank's solution. The results showed that Co, Fe arid Nd have been released into
the physiological medium. In the cytotoxicity test by neutral red uptake and agar diffusion methods, the commercial NdFe-B magnet tested did not present toxicity.
