Abstract

The effects of corrosion on the metallurgical characteristics and structural rigidity of metallic alloys has been a subject of interest for decades. This paper delineates the various researches on pitting corrosion. It reviews the techniques used to study pitting corrosion resistance, susceptibility and inhibition of stainless steel alloys. An extensive discourse can be found on pitting corrosion addressing the initiation and propagation of pits from the work of different authors due to localized corrosion in the presence of chlorides and other halogens and its effects on the electrochemical and metallurgical properties of the steel. Review of various research shows pitting corrosion is excercebated with increase in majorly chloride ion concentration leading to rapid deterioration of the steel alloys. Research also shows pitting corrosion can be controlled through conventional electrochemical techniques and changes substrate metal. The effect of changes in environment on the mechanism and rate of pitting corrosion is discussed.
