The surface treatment methods of shipbuilding steel plates mainly include the following:

Thermal spraying method.
Flame spraying.
Principle: Use the high-temperature flame generated by the mixed combustion of combustible gases (such as acetylene, propane, etc.) and oxygen to heat metal powders or wires to a molten state and spray them onto the steel plate surface to form a coating.
Advantages: Different spraying materials can be selected to meet different anti-corrosion requirements. The bonding strength between the coating and the steel plate is high, and the corrosion resistance is good.
Disadvantages: Professional spraying equipment and technicians are required. High temperature and open flames will be generated during the spraying process, presenting safety risks.

 

 

 

Arc spraying.
Principle: Heat two metal wires (such as zinc wire, aluminum wire, etc.) to a molten state through an electric arc and spray them onto the steel plate surface at high speed to form a coating.
Advantages: High spraying efficiency and stable coating quality. Construction can be carried out on site and is suitable for anti-corrosion treatment of large steel structures.
Disadvantages: High equipment cost. Noise and smoke will be generated during the spraying process.
