EXPERIMENT #9 CORROSION OF METALS

Galvanic corrosion. Corrosion produced by the electromotive force associated with two dissimilar metals. Galvanic series. The arrangement of alloys according to their tendency to corrode in a particular aqueous environment. Inhibitors. Additions to the electrolyte that preferentially migrate to the anode or cathode, cause

AN INTRODUCTION TO CATHODIC PROTECTION OF …

and cathode sites will not exist. Cathodic protection is commonly used on many types of structures, such as pipelines, underground storage tanks, locks, and ship hulls. 1.4 Types of cathodic protection systems. There are two main types of cathodic protection systems: galvanic and impressed current. Figure 1-1 shows these two types.

Stainless Steel in Contact with Other Metallic Materials

If galvanic corrosion occurs, the less no-ble material – the anode – is preferentially attacked whilst the more noble material – the cathode – is even protected against corrosion. In fact, the principle of cathodic protection isbased on sacrificial anodes providing protection from corrosion. The contact of two metals with different
