Application of titanium alloy in water weapons
Underwater weapons have harsh service conditions , among which the impact of mine explosions and seawater corrosion have a particularly serious impact on underwater weapons . Therefore, in structural design , it is required that the shell has the ability to resist high compressive stress , and the structural parts have the ability to resist cyclic stress and fatigue damage. capabilities , while also being corrosion-resistant and lightweight. In order to meet the above requirements at the same time , material selection is particularly important. It is currently an ideal choice to manufacture underwater weapons with titanium-based alloys.
Titanium alloys and titanium-based composite materials are light in weight , bring convenience to use , have good corrosion resistance , facilitate storage and maintenance , and at the same time have high strength, good toughness, and impact resistance , so they are the first choice for underwater weapon structures. However, the wide application of titanium alloys is still limited by their high price . Therefore , an optimized combination method should be adopted in the selection of structural materials for underwater weapons , and titanium alloys should only be used in key parts and important parts. This not only improves the effectiveness of underwater weapons, but also achieves the purpose of reducing manufacturing costs. It is most reasonable to make the main combat part of the broadband acoustic mine sweeping device—the sounder—with titanium alloy. Titanium alloys can also be used to manufacture minesweeper shells or large-depth pressure-resistant shells. In a word , the combination design and construction of underwater weapons with titanium alloy and other metal materials has the following advantages.
1. Improved economy. The product design should have good functions and high quality , and the price of the product should be economical and reasonable. By analyzing the function of the product , the designer can determine which parts choose titanium alloy, which can not only improve the performance of the parts , but also improve the cost performance of the whole product.
2. Good design and workmanship. The macro-mechanical properties of titanium alloys can be designed . Its comprehensive mechanical properties are good , and it is easy to manufacture components with various complex shapes . It is easy to use the overall structure to form at one time , thereby reducing weight, saving raw materials and working hours , increasing the reliability of components and improving the structure. Bearing characteristics.
3. can improve some physical properties. The sound generator of Rusheng mine-sweeping equipment is made of titanium alloy, and its impact resistance and corrosion resistance have been greatly improved.
