• **Galvanic/bimetallic corrosion**

 Galvanic corrosion takes place when dissimilar metals come in contact with each other when exposed to an electrolyte. In this type of corrosion, one metal deteriorates quickly by an electrochemical reaction while the other remains unaffected. This is

due to the magnitude of the potential difference between the two metals [9]. **Figure 3** illustrates the galvanic corrosion in metals.
