Inhibition is one of the most efficient methods of corrosion protection in many environments. However, most inhibitors provide synergitic properties when used in combination with other methods of corrosion protection. This report presents results of research on soluble inhibitors in combination with cathodic protection systems. Quoted parameters and critical concentration make corrosion prevention possible in different
environments. It is established that inhibitors increase efficiency and longevity of protection. We have found that the consumption of inhibitors and the current of cathodic protection decrease 3-20 times. Soluble inhibitors together with cathodic protection systems should be used when corrosion protection is required in aqueous media, such as
seawater, oil, gas, etc.
