As the key parts of the ship, the wear resistance 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 surface treatment technology and wear resistance improvement of Marine rudder forgings in order to improve the wear resistance and prolong the service life of the products.
Surface treatment technology refers to the treatment of the surface of the material through physical or chemical methods to change its surface morphology, chemical composition and organizational structure to achieve the purpose of improving wear resistance. Common surface treatment technologies include spraying, electroplating, carburizing, etc.
Spraying technology: Spraying technology is a method of blowing molten spray material to the surface of the forging through high-speed air flow to form a coating. Commonly used spraying materials include zinc, aluminum, chromium, etc., which have good corrosion resistance and wear resistance. The wear resistance of Marine rudder forgings can be effectively improved by selecting suitable spraying materials and process parameters.
Electroplating technology: Electroplating technology is a process that uses the principle of electrolysis to deposit a layer of metal or alloy on a metal surface. Commonly used electroplating materials include nickel, chromium, etc., which have good hardness and wear resistance. The wear resistance of Marine rudder forgings can be improved by selecting suitable electroplating materials and process parameters.
Carburizing technology: Carburizing technology is a method of forming carbides or graphitized structures by penetrating carbon atoms into metal surfaces. Carburizing technology can improve the hardness and wear resistance of metal surface, which is suitable for high load and high wear conditions. Better wear resistance can be obtained by controlling carburizing temperature and time.
Wear resistance improvement
Material selection: The selection of materials with high hardness and high wear resistance is the basis for improving the wear resistance of Marine rudder forgings. Commonly used wear-resistant materials include high carbon steel, alloy steel and so on. After proper heat treatment and surface treatment, these materials can significantly improve their wear resistance.
Structure design: Reasonable structure design can effectively reduce the wear of Marine rudder system forgings. By optimizing the geometry and size parameters of the parts, reducing the stress concentration and impact force, the wear resistance of the parts can be improved. In addition, strengthening the strength and stiffness of key parts is also an important measure to reduce wear.
Processing technology: The use of advanced processing technology can effectively reduce the wear of Marine rudder forging. For example, the use of precision casting, heat treatment, grinding and other processes can improve the surface quality and dimensional accuracy of parts, and reduce the wear rate. At the same time, reasonable selection of cutting parameters and tool materials is also a key factor to reduce wear.
Lubrication and maintenance: Good lubrication and maintenance is an important measure to improve the wear resistance of Marine rudder forgings. Through regular lubrication and inspection, timely replacement of severely worn parts, you can extend the service life of the product. At the same time, strengthening the maintenance and maintenance of equipment is also an important means to reduce wear.
The surface treatment technology of Marine rudder system forgings and the improvement of wear resistance are of great significance for ensuring the safety, stability and prolonging the service life of ships. By selecting suitable surface treatment technology and process parameters, and optimizing material selection, structural design, processing technology and lubrication maintenance measures, the wear resistance 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 wear resistance and reliability of Marine rudder forgings, in order to meet market demand and promote the sustainable development of the Marine industry.
