Introduction
Galvanizing is a process of coating steel or iron with a layer of zinc to prevent rusting. In Tamil, it is called “கல்வனைகள்”. This process is widely used in various industries to protect metal from corrosion and increase its durability. In this article, we will explore the meaning of galvanizing in Tamil and its importance in the industry.
What is Galvanizing?
Galvanizing is a process of applying a protective layer of zinc on steel or iron to prevent rusting. The process involves immersing the metal in a bath of molten zinc, which forms a protective layer over the metal. The zinc layer serves as a sacrificial coating that corrodes before the steel or iron, protecting it from rusting.
The Importance of Galvanizing
Galvanizing is an essential process in the industry as it provides several benefits:
- Protection from rust and corrosion
- Increased durability and longevity
- Lower maintenance costs
- Resistance to harsh environmental conditions
Types of Galvanizing
There are several types of galvanizing processes:
- Hot-dip galvanizing
- Electrogalvanizing
- Sherardizing
Hot-dip Galvanizing
Hot-dip galvanizing is the most widely used process, where the metal is dipped in a bath of molten zinc. The process creates a thicker, more durable layer of zinc on the metal. This process is commonly used in the construction industry for steel structures, bridges, and other infrastructure.
Electrogalvanizing
Electrogalvanizing is a process where a thin layer of zinc is applied to the metal using an electrical current. This process is commonly used in the automotive industry for parts such as car bodies and fenders.
Sherardizing
Sherardizing is a process where the metal is heated in a zinc powder mixture, which forms a zinc-iron alloy coating. This process is commonly used in the manufacturing of small parts such as screws and bolts.
Conclusion
Galvanizing is a process that is widely used in various industries to protect metal from rust and corrosion. In Tamil, it is called “கல்வனைகள்”. There are several types of galvanizing processes, including hot-dip galvanizing, electrogalvanizing, and sherardizing. The process provides several benefits, including increased durability, resistance to harsh environmental conditions, and lower maintenance costs. Overall, galvanizing is an essential process in the industry for protecting metal and increasing its longevity.
