galvanic series การใช้

• The reaction is spontaneous because copper is higher on the galvanic series than iron.
• The table below shows a simplified galvanic series which is used to select the anode metal.
• The table below shows a simplified galvanic series to show which metals can thus be combined . [ 9]
• Galvanic anodes rely on the galvanic series potentials of the metals to drive cathodic protection current from the anode to the structure being protected.
• Under many application conditions copper is higher on the galvanic series than other common structural metals, meaning that copper wire is less likely to be corroded in wet conditions.
• Magnesium has the most negative electropotential of the three ( see galvanic series ) and is more suitable for areas where the electrolyte ( soil or water ) resistivity is higher.
• A " galvanic series " is a hierarchy of metals ( or other electrically conductive materials, including composites and semimetals ) that runs from " noble " to " active ", and allows one to predict how materials will interact in the environment used to generate the series.
