Steel rails resist corrosion through a process called passivation, where a protective layer of oxide forms on their surface, preventing further oxidation and corrosion. Additionally, modern steel rails are often coated with various protective coatings, such as zinc or epoxy, to enhance their resistance to corrosion even further.
Steel rails resist corrosion through a process called galvanization, where a protective coating of zinc is applied to the surface. The zinc layer acts as a sacrificial anode, corroding in place of the steel, thereby preventing rust formation and preserving the integrity of the rails.
Steel rails resist corrosion due to the presence of a protective oxide layer on their surface, which forms naturally when exposed to oxygen in the air. Additionally, the rails are often coated with a layer of paint or a protective coating that acts as a barrier against moisture and other corrosive elements. Regular maintenance, such as periodic cleaning and repainting, also helps to prevent and control corrosion.
