Galvanic Corrosion Protection

Cor-Pro Systems is the leading provider of galvanic corrosion protection in Houston Texas.

Companies relying on metal structures, machineries, and equipment acknowledge the importance of galvanic corrosion protection in their profit.

Corrosion, in its many forms, is a trillion dollar problem for industries in the United States alone.

It’s a very serious problem facing many businesses; more so for those that have seawater installations or operate in the transportation industry.

Cor-Pro Systems provides top of the line galvanic corrosion protection that include custom-made solutions depending on the specific business needs.

What Is Galvanic Corrosion?

Galvanic corrosion is the result of an electrochemical reaction wherein one metal gets in contact with another metal. One cathode metal decreases its corrosion potential at the expense of the more active metal, known as anode.

The corrosion happens when water or road salt acts as the conductor. The most common conductors are sodium chloride, calcium chloride and magnesium chloride.

Every metal has a corrosion potential the more dissimilar the two metals are, the higher the chance (and the stronger the rate) of galvanic corrosion.

Industries Affected By Galvanic Corrosion

Equipment, structure, or transportation that are immersed in seawater are more affected than other installation.

For example, an aluminium and carbon steel installation is immersed in seawater, the rate of corrosion is quicker, wherein the aluminium corrodes while the carbon steel receives protection.

Galvanic Corrosion Prevention Techniques

Galvanic corrosion protection has never been more important, and companies should be aware of the techniques utilized by experts like Cor-Pro Systems.

  • Selecting metals or materials with similar corrosion potentials
  • Insulating two dissimilar metals from each other to break the electrical connection
  • Applying protective coatings to both metals, wherein the coating on the cathode is in really excellent condition
  • Inserting a suitably-sized spacer to separate the two dissimilar metals
  • Adding Corrosion inhibitor to the environment where the two metals are placed
  • Installing a sacrificial anode that is anodic to both metals

These galvanic corrosion techniques, if properly executed, could reduce corrosion considerably.
