Factors affecting cathodic deposition of metals
Answers
Atmospheric corrosion is highly visible compared to other corrosion processes. You can see its effects on flag poles, rusty bridges, monuments and buildings. Since it's pretty evident in almost all operations and industries, a huge portion of the paint industry is dedicated to the production of metal protectors that are doing their part in controlling atmospheric corrosion.
Almost all kinds of general corrosion take place within the atmosphere. In most cases, the metals undergoing corrosion are not exposed to huge electrolyte quantities, so atmospheric corrosion in such conditions activates in corrosion cells that are highly localized. At times, atmospheric corrosion creates various patterns that are tough to explain, such as those seen on rusty galvanized roofs.
