Corrosion Control by Material selection & Metallic Coating

Material Selection and Metallic Coating for Corrosion Control describes how metals coatings can prevent corrosion from metal corrode.
Corrosion control is a process aimed at reducing the corrosion rate to a tolerable level (or predictable limits). This process consists of different corrosion monitoring and control techniques, used by industries to reduce the problem of corrosion.

Corrosion control focuses mainly onrn(1) Material andrn(2) Environmentsr
Corrosion Management focuses on “people” and aims at improving the performance of engineering systems. So, effective corrosion control requires a complete management strategy involving people as much as equipments.
corrosion management and control

Since corrosion involves interaction between material and environment, the approach to control corrosion includesr
Use of the most compatible material in a given environment.
Reduce the aggressiveness of the environment towards the material.
Use of protective coating to separate the material from the environment.
Cathodic and anodic protection are preventive measures based on electrochemical principles of corrosion.

2. Material Selection:
Technically, selecting a corrosion – resistant alloy would be the answer to corrosion problemr
However, corrosion resistance is not the only property to be considered when selecting a material. (It is of major importance in the chemical process industries).
Economics (cost) dictate the selection of material.
The most corrosion – resistant metal or alloy may not be always optimum choice because of:
