Thermal spray alluminium coating

Thermal spray aluminum coating, commonly referred to as aluminizing, is a specialized process designed to protect metal surfaces from corrosion and oxidation, especially in high-temperature environments. Madhu Metallizing India Pvt Ltd, based in Bangalore, has established itself as a leader in this domain, offering state-of-the-art aluminizing services that adhere to stringent national and international standards.​madhumetallizing.com

Understanding the Aluminizing Process

Aluminizing is a thermal spray technique where molten aluminum is deposited onto a prepared substrate. The process begins with surface preparation, typically involving abrasive blasting to clean and roughen the surface, ensuring optimal adhesion of the aluminum coating. Once prepared, aluminum wire with a purity of 99.5% is melted using an electric arc. The molten aluminum is then atomized using compressed air and sprayed onto the substrate, forming a dense, protective layer. This method is considered a "cold process" because the substrate remains relatively cool, preventing thermal distortion or damage.

Applications of Thermal Spray Aluminum Coating

Madhu Metallizing India's aluminizing services are particularly beneficial for equipment and structures exposed to high temperatures and corrosive environments. Common applications include:Industrial Chimneys and Stacks: Protecting against flue gas corrosion.​

• Boilers and Heat Exchangers: Enhancing resistance to oxidation and thermal fatigue.​

• Ducts and Preheaters: Preventing corrosion from high-temperature gases.​

• Marine Structures: Shielding against saltwater-induced corrosion.​
