Galvanic Corrosion Testing

Element offers galvanic corrosion testing to ASTM G71,  ASTM G82 and to client-specific standards for evaluating the behavior of metals and metallic coatings in accelerated corrosion environments. We can help you select appropriate materials at the design stage and offer in-field support for fast answers in live applications. 

What is Galvanic Corrosion Testing and why is it Essential? 

Galvanic corrosion is a natural electrochemical process that occurs when two different metals come into contact with an electrolyte, such as sea water. When this happens, one metal becomes the anode, and the other becomes the cathode. The anodic metal corrodes more quickly, while the cathodic metal corrodes slower than usual (or may not corrode at all).

Galvanic corrosion testing is essential to assess the potential risk of damage to metal structures and equipment. By understanding the galvanic corrosion potential of different metal combinations, you can take preventive measures to mitigate or eliminate the risk of corrosion, ensuring the longevity and safety of materials.
