The application of titanium alloy in vessels has improved the service life of vessels and the performance of equipment in the marine environment. Therefore, titanium and titanium alloys are known as "the future metal", "the third metal", "marine metal" and so on.
Titanium and titanium alloy materials are widely used in vessels. All large equipment and parts other than vessel's appurtenances and cabin facilities may be used in titanium and titanium alloy materials, such as electronic information system, electric power system, auxiliary system, hull structure parts, propulsion system, etc.
Pressure-resistant housing
In the field of naval vessels, the main applications of titanium alloy pressure-resistant housings are bathyscaphes and submarines. The characteristics of titanium alloy such as high specific strength, good corrosion resistance and non-magnetic make it a high quality material for manufacturing pressure-resistant shells of deep-sea equipment.
Power propulsion device
Propellers of vessels need to have high corrosion fatigue strength and corrosion resistance due to the influence of seawater and marine climate, propeller materials. Compared with copper alloy and steel, titanium alloy has advantages in corrosion fatigue strength and corrosion resistance. In addition, due to its low density, titanium alloy propellers have a small mass compared to other commonly used materials when making propellers of the same size. As a result, vessels using titanium propellers have higher drive efficiency. Combined with the high corrosion fatigue strength and corrosion resistance of titanium propellers, their maintenance and servicing will be easier, extending the service life of the propeller. Titanium alloy is the ideal naval propeller material.
Acoustic device
Titanium alloy materials can also be used for the manufacture of acoustic devices on vessels, such as sonar deflectors, hydroacoustic transducer components, microphones, telephone parts, etc. Sonar is the most effective equipment for target detection by vessels underwater.
vessels are an important part of national naval power, and it is crucial to choose excellent materials for shipbuilding. Titanium alloy materials have many excellent properties and can be widely used in shipbuilding. The world's military powers have been developing and applying titanium alloys for vessels for decades, and have many successful cases in vessel hulls, power propulsion devices, pipelines, sonar and so on. At present, these countries still regard titanium alloy as a new material of strategic significance and attach importance to the research and application of titanium alloy. In the future, there will be more kinds of titanium alloy materials with excellent performance and successful application cases.
