Application of titanium in the field of ocean engineering

With the development of science and technology and the exhaustion of land resources, human exploitation and utilization of the sea has been put on the agenda. Titanium has excellent corrosion resistance to sea water and is widely used in seawater desalination, ships, ocean thermal energy development and seabed resource exploitation.

As early as the 1960s, China has started to study the application of titanium and titanium alloy in ships and ocean engineering equipment, and done a lot of work, has basically formed a Marine titanium alloy system with many grades, different properties and complete varieties and specifications. Due to the characteristics of titanium and titanium alloy itself, it has unique advantages in the application of ships and sea engineering equipment, and is widely used in nuclear submarines, deep submersible, atomic energy icebreakers, hydrofoil, hovercraft, minesweeper and propeller, seawater pipeline, condenser, heat exchanger and so on.

In terms of ship application, the amount of titanium used for ships in China is very small at present, accounting for less than 1% of the total weight of ships. There is huge development potential in the field of reserve titanium and titanium alloy for ships and Marine tools. In addition, in terms of sea water desalination and coastal power stations, due to the huge market demand for sea water desalination and coastal power stations in China, titanium will have a very broad market application prospect under the condition of further reducing the cost of titanium alloy and improving the stability of product quality.
