Why Choose Titanium Parts Of Marine Equipment for Marine Equipment?

2025-05-09

The application logic of titanium parts of marine equipment comes from the strict screening of the intrinsic properties of materials in the marine environment. This type of ship components with titanium-based alloys as the main structure obtains the dual advantages of corrosion resistance and mechanical strength through crystal structure regulation. The tendency of chloride ion penetration in the seawater electrolyte environment is effectively blocked by the semiconductor properties of the self-repairing oxide film on the titanium surface, and the electronic transition energy level design of the passivation layer inhibits the chain reaction of electrochemical corrosion.

The slip system activation characteristics of the close-packed hexagonal lattice of titanium alloy during cold working enable titanium parts of marine equipment to maintain high specific strength while being compatible with plastic forming requirements. The anisotropy of the thermal expansion coefficient is balanced by the solid solution strengthening of the alloy elements, which meets the dimensional stability requirements of ships under temperature alternating working conditions. The alternating stress caused by the hydrodynamic load is absorbed by the dislocation pinning effect of the β-phase grain boundary, avoiding the accumulation of the risk of stress corrosion cracking.


The tendency of marine organisms to attach is suppressed due to the mismatch between the energy level of the titanium surface and the intermolecular forces of biofilm proteins. This anti-fouling property reduces the continuous growth of fluid resistance. The natural lack of magnetic permeability allows titanium parts of marine equipment to avoid electromagnetic interference in areas with dense navigation equipment, while meeting the stealth requirements of specific ships.
