Abstract:
Localized corrosion under droplet of corrosive media is one of the most common forms of corrosion for metallic structures exposed to atmosphere and/or moisture in the air. This scenario is mainly responsible for the economic cost of materials due to corrosion and its prevention on every-day-life. In this study, pitting corrosion monitoring method under droplet of electrolyte generated by means of fluid handling device was simulated under wet-dry cyclic condition in order to examine pit initiation and propagation. Wet-dry cycle process started with a droplet of sodium chloride solution on the surface of stainless steel specimen in certain volumes and sizes, the specimen was then left until the sodium chloride droplet was completely evaporated in the temperature-humidity controlled condition, i.e. 10% and 60% relative humidity (RH) at 27°C. As time increase, water evaporated salt deposit presented. This considers as a completion of one wet-dry cycle. Next cycle proceeded by a droplet of deionized water on the previous same location as the saline solution and the droplet was left until completely dried again. The cycle continued until red brown rust can be visually noticed. The time required to finish each cycle was varied depending on temperature and humidity, electrolyte droplet morphology and concentration. After finishing the wet-dry cycles and the rust was noticed, the specimens were characterized under laser optical microscope. The study on the development of a methodology using droplet and wet-dry cycle for pitting corrosion monitoring is discussed here.
