Hot corrosion is a type of accelerated corrosion that occurs in high-temperature environments, often affecting gas turbines, boilers, and other industrial equipment exposed to combustion gases. It is primarily caused by the presence of molten salts, such as sulfates and chlorides, which react with metal surfaces to form corrosive compounds that degrade the material's integrity.

High-temperature environments

Gas turbines are a type of internal combustion engine that convert natural gas or other liquid fuels into mechanical energy, which is then often converted into electrical energy. They are widely used in power generation, aviation, and industrial applications due to their high efficiency and ability to rapidly start and stop.

Gas Turbines

Boilers are closed vessels that heat water or other fluids to generate steam or hot water for various applications, including heating, power generation, and industrial processes. They operate through the combustion of fuels or the use of electricity, transferring heat to the fluid inside while maintaining safety and efficiency standards.

Molten salts

Sulfates are salts or esters of sulfuric acid containing the anion SO4^2-, widely used in industrial processes and consumer products, including detergents and cosmetics. They are known for their ability to create lather and remove oils, but can also cause skin irritation and environmental concerns due to their potential impact on aquatic life.

Sulfates

Chlorides are chemical compounds that consist of chlorine and another element, often forming salts that are highly soluble in water. They play crucial roles in various biological and industrial processes, including water purification, food preservation, and as electrolytes in the human body.
