Titanium And Ocean - Applications And Prospects Of Titanium in The Marine Field

In recent years, in order to improve the level of naval equipment in China, the state's investment in the field of ships has begun to increase. Many new projects are being developed, such as submarines, new destroyers, etc., and the potential for titanium use is huge. As an ideal material for ships, titanium and its alloys are expected to have very broad market prospects in the future. The shipbuilding industry is expected to become another large application market for titanium after the aerospace field. 

Advantages of Titanium Boats:

1. The Hull is Light. For a ship of the same size, the hull quality of titanium is 30% of FRP, 10% lighter than aluminum alloy. Since the surface of the titanium ship does not need to be sprayed with anti-rust paint, the quality of the paint is also omitted.

2. Speed Increased. Due to the light weight of the ship, the ship's engine may be miniaturized. In addition, no paint on the surface of the ship is in direct contact with the water, which also reduces the coefficient of friction with the water, thereby improving the speed of the ship.

3. Fuel Costs and CO₂ Generation Are Reduced. The light weight and high speed of the titanium ship have greatly reduced the fuel cost per unit mass and per unit sailing distance. This is not only a reduction in funding for navigation, but also a reduction in CO₂ generation, which is very effective in preventing global warming, which has become an international problem.

4. Corrosion Resistance. Titanium plates are as corrosion resistant as pt in seawater. Therefore, that is not necessary to spray anti-corrosion paint.

5. Recycling of scrap ships. FRP ship waste is difficult to recycle,so far has not found a simple and practical way. The titanium ship is the same as the aluminum ship, and the waste can be recycled and reused, which is conducive to environmental protection.

6. Excellent Stability. Even in bad weather, titanium ships rarely shake vertically and horizontally,and they can sail stably at high speed.

7. Low noise and vibration. The noise is small when idling,and the vibration caused by the shock from the waves during sailing is not large. This is a survey of titanium speedboats.

8. Long Life. From the actual results of the survey, it is speculated that the legal service life of the Ti ship is much longer than that of steel and aluminum, and the actual life will be longer.
