Abstract
The purpose of this research was to study the pitting corrosion initiation mechanism in different solutions containing chloride, sulfate and nitrate on steel in atmospheric environment. The research used experimental methods with ASTM A36 steel as the workpiece and digital microscopes to observe the corrosion that occurs by varied volumes of droplet solution (10 to 50 μL) on the surface of the workpiece. Afterwards, the critical time for pitting to initiate and the number of pitting were measured as parameters of corrosion resistance of steel in atmospheric. This research also shows that the anion of chloride is has the fastest in terms of initiating the pitting corrosion than the anion of sulfate and nitrate.
