The process of galvanization ages back to almost 300 years ago. The term ‘galvanization’ is related to Italian scientist Luigi Galvani, whose involvement with the process is however disputed. Today it is considered one of the important electrochemical processes in the industry.
The existence of Zinc, an essential element for galvanization, has been interlinked as a medium that holds a strong significance dating back to the early days. Evidence has been found for galvanization to exist within something as simple as the ornaments people in the earlier days used to wear. The dipping of the metal in the liquid allowed the preservation of these ornaments instead of them getting damaged to date.
In the year 1742, a description was given on how a coating of zinc could be applied to iron by immersing it in the same. This description was given by Melouin, a chemist in a paper presented to the French Royal Academy.
Melouin’s presented facts ignited interest amongst various people in experimental science. This led to the application of molten zinc on household utensils. An affordable medium to provide protection. During the second half of the 18th century, these products started gaining recognition due to the advantages they had to offer.
In the 19th Century, the term ‘galvanization’ was coined by Sorel, a French industrialist. Initially, the term was coined to describe the accommodation of electric shocks. Prior to this, there were several metals that were tested with molten zinc. The reasons were everything but the purpose for which steel is galvanized today.
Sorel carried out an experiment where he cleaned steel and then immersed it in molten zinc. Around this very time, a man named William Crawford also carried out a similar experiment in Britain. Thus, they share the patents. Initially, this term was given to the property of the metal and not the process. This, however, changed with time.
Progressing with time
As time passed, how was galvanization mobilized in the industries?
The perks of galvanizing were recognized massively in the coming years.
Britain reportedly produced a huge amount of zinc that was used for the protection of iron. Did you know that galvanized iron was used in world wars?
In India, galvanized metal was found in the royal armors and weapons belonging to the 18th Century. Similar incidents traced the existence of galvanization. The benefits of this corrosion-resistant process are many. Along with construction, galvanization was also used in industries like agriculture, power, refineries, transport. Wherever there is a requirement for utilizing anti-corrosive metal, galvanization came into play.
Following are some of the incidents that have employed the electroplating of zinc:
As technologies evolved, the entire method of hot-dip galvanization changed. The process is more meticulous unlike the older method of simply providing a zinc bath.
By the 20th century, industrialists invested in utilizing galvanized steel to create structural frames for their construction. The corrosion-resistant property gained massive popularity by this time. A process manufacturing unit could not work without. Galvanization recognizes itself as one of the stages for the production of prefabricated steel. Manufacturers employ a series of procedures like cleaning, rinsing, zinc bath, and drying being the major ones. The entire process can take around 24-48 hours.
