As a key part of the ship, the anti-corrosion performance of the Marine rudder forging is of great significance to ensure the safety, stability and prolong the service life of the ship. This paper will study the anti-corrosion performance and anti-rust technology of Marine rudder forgings in order to improve the anti-corrosion ability and prolong the service life of the products.
Marine rudder system forgings are used in Marine environment, facing the challenge of various corrosive media and harsh environmental conditions. Therefore, it is very important to improve the corrosion resistance of the product.
Material selection: The selection of materials with excellent corrosion resistance is the basis for improving the corrosion resistance of Marine rudder forgings. Commonly used corrosion resistant materials include stainless steel, nickel base alloy, copper base alloy and so on. These materials have good corrosion resistance and stability, and can adapt to various corrosive media in the Marine environment.
Surface treatment: Surface treatment is an important means to improve the corrosion resistance of Marine rudder forgings. Common surface treatment methods include spraying, electroplating, chemical conversion and so on. By forming a dense protective film on the surface, the corrosion resistance of the product can be effectively improved.
Structural design: Reasonable structural design can effectively reduce the corrosion risk of Marine rudder forging. By optimizing the geometry and size parameters of the parts, reducing the stress concentration and gap, the retention and accumulation of the corrosive medium in the local area can be reduced, thereby reducing the corrosion.
In order to prevent the rust of Marine rudder system forgings in the process of storage, transportation and use, it is necessary to adopt effective anti-rust technology.
Anti-rust oil coating: In the process of storage, transportation and use, a layer of anti-rust oil can be coated on the surface of the Marine rudder system forgings to form a protective film to prevent moisture and corrosive media from contacting the metal surface, so as to achieve the purpose of anti-rust.
Gas phase rust prevention: Gas phase rust prevention technology is a method of treating metal surfaces in a sealed environment using gas phase corrosion inhibitors. By filling the gas phase corrosion inhibitor in the sealed environment, it makes contact with the metal surface, forming a protective film on the surface, so as to achieve the purpose of rust prevention. The advantages of this method are good anti-rust effect, easy to use, and suitable for large-scale components.
Rust-proof packaging: For Marine rudder forgings that require long-term storage, rust-proof packaging technology can be used. Put the forgings into a dry packing box, add an appropriate amount of desiccant and rust inhibitor, and seal the packing box to keep the forgings dry and rust resistant.
Regular inspection and maintenance: In the process of storage, transportation and use, the surface condition of Marine rudder system forgings should be regularly checked, timely detection and treatment of rust and damage. At the same time, strengthen the maintenance and maintenance of the equipment to maintain its good operating condition and service life.
The anti-corrosion properties and anti-rust technology of Marine rudder forgings are of great significance for ensuring the safety, stability and prolonging the service life of ships. By selecting suitable anti-corrosion materials and surface treatment methods, and adopting effective anti-rust measures and technologies, the anti-corrosion performance and anti-rust ability of Marine rudder system forgings can be effectively improved, and the service life can be extended. In the future development, enterprises should strengthen technological innovation and research and development efforts, and constantly improve the manufacturing technology and surface treatment level of Marine rudder forgings, as well as optimize rust prevention technology and packaging programs to meet market demand and promote the sustainable development of the Marine industry.
