Abstract
Responsible application of metals with shape memory needs to know degradation processes taking place during their exploitation in real conditions. The contribution investigates corrosion properties of an Ni-Ti alloy containing 55.2 % Ni and 44.8 % Ti in physiological salt solution (0.9 % NaCl at 40 ± 1 °C). The performed laboratory tests found out a high corrosion resistance of the material used mainly in human medicine for implants. By measuring the electrochemical characteristics it could be acknowledged that this is related to the formation of a passive state on the alloy surface during its exploitation.
