Many alloys exhibit the shape memory effect, but only the Cu-Al-Zn, Cu-AI-Ni, and Ni-Ti alloys
are presentand of commercial importance. The greatest use of these alloys is in biomedicine
(filters, orthodontic implants, guide wires for catheters, etc.). Shape-memory alloys may be found
in sensors in automobiles, consumer products, and generally in smart materials.
The electrochemical behavior of Cu-Al-Zn alloy in phosphate buffer without and in the presence
of cysteine was investigated.
Electrochemical researchwas performed in a traditional three-electrode system by means of the
Tafel extrapolation method. The results showed that the presence of cysteine leads to a decrease
in the corrosion rate and the density (values) of the corrosion current, which indicates that the
