Why Galvanization of Industrial Components is Essential? Â

What is Galvanization? • The process of application of protective zinc coating to iron or steel in order to prevent them from rusting is called galvanization. • Galvanization by forming a coating of zinc on the metals prevents any corrosive substance from reaching it.

What is Hot Dip Galvanization? • Hot dip galvanizing is the most common method of galvanizing. This process includes the submergence of iron or steel in a molten zinc bath. • This process acts as a barrier between the atmosphere and steel and even if the galvanized coating gets damaged and steel gets exposed to the atmosphere, the zinc with the help of galvanic corrosion protects the steel.

History Of Galvanization • The history of galvanizing starts over 300 years ago, when an alchemistcome-chemist dreamt up a reason to immerse clean iron into molten zinc and to his amazement, a shimmering silver coating developed onto the iron. This was to become the first step in the genesis of the galvanizing process. • The famous Indian medical text, Charaka Samhita, written around 500 BC, mentions a metal which when oxidised produced pushpanjan, also known as ‘philosopher’s wool’, thought to be zinc oxide.

• 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. • Galvani incorrectly concluded that the source of the electricity was in the frog’s leg. The term ‘galvanization’ began to appear in the lexicon, connected partly to the work carried out by Michael Faraday.

Galvanizing Today • Galvanized steel is all around us and plays a vital role in our everyday lives. It is used in construction, transport, agriculture, power transmission and everywhere that good corrosion protection and long life are essential. • It, for instance, helps light our roads and provide power for our homes, hospitals and offices (high voltage pylons) There are many other important industries that make use of galvanizing. • Zinc the essential raw material for hot dip galvanizing is a highly recyclable metal which is vital for human health and ecosystems. www.galvanizers.co.in

Why Galvanize? Sacrificial Protection
Barrier Protection
• Zinc corrodes in preference to steel and sacrifices itself to protect the steel, hence hot dip galvanizing will provide this sacrificial protection. The corrosion products from the zinc are deposited on the steel resealing it from the atmosphere and therefore stopping corrosion.
• Galvanizing provides a barrier protection between all internal and external steel surfaces and their environment. The life expectancy of a zinc coating is largely determined by its thickness. Thicker coatings give longer life.
