Corrosion Performance Of Zn-Al-Cd Alloy In Amphora-Containing F/2 Culture Medium

The corrosion properties of Zn-Al-Cd alloy in Amphora-containing culture media were investigated by using electrochemical AC impedance method, polarization curve research, and surface microstructure analysis methods. The results showed that the corrosion rate of Zn-Al-Cd alloy in f/2 culture medium with Amphora was greater than that of samples in sterilized culture medium. SEM micrographs proved that many corrosion pits occurred on the surface of the anode in the Amphora-containing environment. Amphora adhered on the surface of the specimen could produce oxygen, which increased the corrosion of Zn-Al-Cd alloy.
