Key Ways You can Prevent Corrosion

Corrosion is the process of forming voltaic (or galvanic) cells in which the metal works as an anode and worsens or loses operational stability.

Fremont, CA: Corrosion is among the most serious worries for industrialists. It affects both steel and concrete surfaces under the influence of acids, alkalies, chemicals, solvents, and other corrosive substances. Globally, metal loss due to corrosion results in a loss of over 5,000 dollars per year. Many corrosion engineering firms combine industrial knowledge in assessing and managing microbiological and generalized corrosion in fire suppression systems (FPS). Steel corrosion comes in a variety of forms, each with its own set of structural consequences, as shown below. As a result, understanding Corrosion Prevention Methods is critical.

Ways to prevent Corrosion Prevention 

Barrier Coating 

A barrier coating creates an insulating & physical barrier, preventing corrosive materials, such as the electrolyte, from coming into contact with the substrate. When metals and ceramics are unable to survive extremely demanding working conditions, barrier coatings are often helpful. However, the barrier coating material's properties must match the underlying substrate's.

Hot-dip galvanization 

A type of galvanization is hot-dip galvanization. It is the process of coating steel and iron with zinc and then alloys with the base metal's surface when the metal gets immersed in a bath of molten zinc at roughly 449 °C (840 °F). Hot-dip galvanizing provides coverage on both the outside and inside of hollow portions, self-heals when damaged, sacrifices itself to preserve the base metal, is ecologically friendly, and has high impact and abrasion resistance.

Cathodic protection

Cathodic Protection is an electrochemical method that uses DC current to reduce or stop corrosion currents on a metal. When used correctly, CP inhibits the corrosion reaction and protects the integrity of metals. Cathodic protection works by forming a circuit with an anode or anodes (external devices) in an electrolyte. Current passes from the anode to the structure's surface through the electrolyte. Corrosion goes to the anode to prevent the structure from corroding further.
