Define corrosion write the steps prevention of it?

Question

Answer

Answer

When a metal is attacked by substances around it such as moisture , acids,etc.It is said to corrode and this process is called corrosion.

1. Greasing.

2. To keep iron articles away from moisture.

Answer

Corrosion is a decomposition reaction in a metal decompose into rust by action of moisture and air around it

Rusting can be prevented by following ways-
1) by painting
2) by electroplating
3) by galvanishing
4) by adding any anti corrosion element

Answer

Corrosion is defined as deterioration of metal by atmospheric gases it can be prevented by...
painting.
galvanization

Answer

Corrosion and its Prevention

Corrosion is a natural process that occurs when a metal is exposed to an environment that contains moisture, oxygen, and other reactive substances. It is a process that gradually deteriorates the metal over time, leading to structural damage, loss of strength, and eventual failure.

Steps for Corrosion Prevention

1. Coating

Coating is the most common and cost-effective way to prevent corrosion. It involves applying a protective layer of paint, varnish, or other coating materials to the metal surface. The coating acts as a barrier that prevents moisture and other reactive substances from coming into contact with the metal surface.

2. Cathodic Protection

Cathodic protection is a process that involves connecting a sacrificial anode to the metal surface. The sacrificial anode is made of a more reactive metal than the metal being protected. When the anode corrodes, it releases electrons that flow to the metal surface, preventing corrosion.

3. Corrosion Inhibitors

Corrosion inhibitors are chemical compounds that are added to the environment to prevent corrosion. They work by forming a protective layer on the metal surface, reducing the rate of corrosion.

4. Design Modification

Design modification involves changing the design of the metal structure to prevent corrosion. This can include adding drainage systems, increasing ventilation, or changing the material used in construction.

5. Environmental Control

Environmental control involves modifying the environment to prevent corrosion. This can include reducing the humidity level, controlling the temperature, or eliminating the presence of reactive substances.

6. Regular Maintenance

Regular maintenance is essential to prevent corrosion. It involves inspecting the metal surface for signs of corrosion, cleaning the surface, and repairing any damage.

Conclusion

Corrosion can be a costly problem for industries, causing significant damage to equipment and structures. However, prevention is possible through a combination of coating, cathodic protection, corrosion inhibitors, design modification, environmental control, and regular maintenance. By taking these steps, industries can extend the life of their equipment and structures, saving time and money in the long run.

Answer

Corrosion is the process of slow deterioration of solid material due to unwanted chemical reactions. It is commonly seen in most of the metals which have the capacity of going back to their native mineral state. Corrosion can occur in a small concentrated area to form a crack or a pit.

corrosion can be avoided by many ways for example,by painting the surface,applying grease frequently, by glavanising etc.

Answer

CORROSION
It is the process in which metals are eaten up gradually by the action of air, moisture and acids on their surface.
FOLLOWING ARE THE STEPS TO PREVENT CORROSION :
• Painting
• Alloying
• Galvanising
• Chrome plating
• Anodising
• Oiling
• Greasing
• Surface coating
