摘要：
The surface properties and the resistance to corrosion of a metal or alloy are primary determined by their biocompatibility and their behavior in a biological environment. In the organism electrochemical reactions may occur. The biological fluids are electrolytic environments, they assuring the ionic conductivity. Several physical-chemical characteristics of these environments, such as the redox potential, the electric conductivity and the pH have a big influence upon the corrosion phenomenon. In this paper, we have studied the corrosion resistance of steel and copper in biological environments containing amino acids. The electrochemical methods used were the abandon potential, the polarization curves and the impedance measurements.
