Application of Titanium and Its Alloy in Marine Industry

Titanium alloys are widely used in the marine industry due to their excellent corrosion resistance, high specific strength and non-magn tic properties under marine conditions. At present, the parts that titanium has been applied to on ships are: pressure shell, propeller and paddle shaft, sea pipeline, valves and accessories, various pipe joints, heat exchangers, coolers, condensers, engines, parts , lifting device and launching device, acoustic device parts, mooring device, etc.

Titanium pressure vessels are mainly used in deep-sea submersibles and submarines. The United States, France, Japan, and China all use titanium pressure vessels to varying degrees: such as the US deep submersible equipped with titanium observation cabin and control cabin, the dive depth can reach 6100m; Japan uses Ti-6Al - 4V ELI alloy, the depth of dive reaches 6500m; China has also achieved certain results in deep submersible technology.

 

The cavitation corrosion resistance of titanium alloys is far superior to steel and copper-nickel alloys. Therefore, propellers and propeller shafts made of titanium can reduce cavitation corrosion speed, prolong service life and improve propulsion efficiency. Titanium alloy is resistant to high-speed seawater scouring, and it does not cause scouring corrosion even when used at a flow rate of 13 m/s. It is especially suitable for pipelines where the working medium is high pressure, high flow rate, and moving seawater. The use of titanium to make ship-to-sea pipelines and valves also reduces pipe diameter and the thickness of the pipe wall.

In ship engines, titanium alloys are mainly used to make engine discs and blades to substitute heat-resistant steel. With the development of titanium alloys on ships, titanium alloys are increasingly used for ship mooring ropes, anchoring devices, rescue buoys, signal buoys and masts. In addition, titanium alloys are also used to make various microphones, sonar flow guides, telephone parts, underwater acoustic transducer components, and the like.
