We’ll discuss how to prevent rust using each strategy in more detail later in the post. The following are the best ways to prevent rust. In short, the best way to prevent rust is to prevent moisture from reaching the metal, or by using a material that corrodes more slowly. We’ve collected the best ways to prevent rust, so you can find a strategy that works best for your equipment or parts. As with many things, some small preventative measures upfront can save you lots of money, time, and frustration later on. Knowing how to prevent rust effectively can save you money and prevent serious problems. It ruins the functionality and stability of important machinery and it can cost your business thousands. The silvery reflective material was a sign of progress and success of industry.Rust can quickly become a big problem.

The concept of adding rigidity to iron sheets not only allowed for the construction of wide-span roofs without the need for cumbersome load bearing walls but they also looked new in a built environment dominated by stone and timber. In mid-nineteen century Britain sheets of galvanized corrugated iron were seen to be exciting and glamorous. In addition to Sorel’s patent of 1836, A British patent for a similar process was granted in 1837 to William Crawford.Īlthough uncertain, the first use of galvanized corrugated iron is believed to be for the Navy at Pembroke Docks, Wales in 1844. He provided the process with its name ‘galvanizing’. In 1836, Sorel in France took out the first of numerous patents for a process of coating steel by dipping it in molten zinc after first cleaning it. In 1829 Henry Palmer of the London Dock Company was granted a patent for ‘indented or corrugated metallic sheets’, his discovery would have a dramatic impact on industrial design and galvanizing. In 1824, Sir Humphrey Davy showed that when two dissimilar metals were connected electrically and immersed in water, the corrosion of one was accelerated while the other received a degree of protection. The term galvanisation (or galvanization) began to appear in the lexicon, connected partly to the work carried out by Michael Faraday. Galvani incorrectly concluded that the source of the electricity was in the frog’s leg. In 1780, an Italian, Luigi Galvani, discovered the electrical phenomenon of the twitching of a frog’s leg muscles when contacted by two dissimilar metals, namely copper and iron.

The zinc surface reacts with the atmosphere to form a compact, adherent patina that is insoluble in rainwater.The zinc protects its base metal by corroding before iron.The zinc serves as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the remaining zinc.

It forms a barrier that prevents corrosive substances from reaching the underlying steel or iron.

Galvanizing protects from rust in a number of ways: The most common method is hot dip galvanizing, in which steel sections are submerged in a bath of molten zinc. Galvani s ation or galvani z ation (or galvanizing as it is most commonly called) is the process of applying a protective zinc coating to iron or steel, to prevent rusting.
