For example , by installing an anode near a metal structure , the areas of the
metal ( anodic or cathodic ) within the range of the electrolyte all become
cathodic . This current , when properly applied , opposes the corrosion current
from the ...

When electrically connected to the structure , these anodes are self - energizing .
They are also self - consuming ( sacrificial ) and need periodic replacement . The
most frequently used sacrificial galvanic - anode metals are high purity zinc ...
