WebMay 5, 2024 · The galvanic potential is specific for a specific electrolyte, temperature and flow rate. The diagram refers to flowing sea water and temperature in the range 10 to 30 ℃. Galvanic series chart shows … WebGalvanic corrosion is due to electrochemical potential between two unlike metals in ionized solution such as might be found in the human body. Normally, a passive oxide layer is formed that protects the metals from corrosion. However, the scratch or fretting wear could make the passivation layer vulnerable to the corrosion. serveilence cameras south seattle
