Aplicación de aleación de aluminio en buques de guerra.

As we all know, the current lightweight development of the shipbuilding industry is inseparable from the application of aluminum alloy materials. The reason is that aluminum alloy materials have the advantages of small specific gravity, good corrosion resistance, good processing and forming performance, good welding performance, and small elastic modulus. Aluminum alloy used in ships has excellent corrosion resistance, so aluminum alloy ships must be able to effectively resist the adverse effects of seawater on the use and service life of ships. Seawater is an electrolyte solution, and the corrosion process of seawater on aluminum alloy is an electrochemical corrosion process, which is in the form of pitting corrosion. The corrosion rate of 5000 series alloys by seawater is extremely slow, among which low-magnesium alloys are more resistant to corrosion; 6000 series alloys can reach 100 percent corrosion resistance to seawater. For this reason, 5000 series alloys and 6000 series alloys have been widely used in the marine field. In addition, the corrosion process of aluminum alloys is quite complicated, which is often affected by the properties of the alloy and environmental factors. Environmental factors include humidity, temperature, pressure, stirring, stray current and corrosive media, etc.; the properties of the alloy include stress and uneven structure. Sex and so on. It can be seen that the application of aluminum alloy for ships must fully consider its influencing factors, thereby improving the overall performance of aluminum alloy ships.
