Inhibitor

A material that prevents or delays oxidation and galvanic action on a connector surface, or the interface of different conductors. Also, a chemical compound, inorganic or organic, which is added to the pickling bath for the purpose of retarding the chemical action of the acid on the steel, while allowing it to continue on the iron oxides and scales until they are dissolved or removed, and the steel surface is perfectly clean. They also assist in preventing hydrogen embrittlement.
