H. Tomas et al., CAST CO-CR ALLOY AND PURE CHROMIUM IN PROTEINACEOUS MEDIA - AN ELECTROCHEMICAL CHARACTERIZATION, Journal of materials science. Materials in medicine, 5(6-7), 1994, pp. 446-451
An electrochemical characterization (by linear sweep cyclic voltammetr
y and chronoamperometry at constant potential) of a cast Co-Cr alloy a
nd of pure chromium was performed and their behaviour compared using N
aCl 0.15 M and albumin-containing solutions as electrolytes. The amoun
t of ions released was determined. The protein detrimental effect over
both materials was detected. Metallic surfaces were also investigated
by X-ray photoelectron spectroscopy and observed by means of optical
and scanning electron microscopy.
