Core Functions of Each Layer of Materials and the Comprehensive Performance after Composite
The essence of this structure lies in the firm combination of the three through metallurgical methods (such as explosive cladding and rolling cladding), achieving a performance of "1 + 1 + 1 > 3".
Performance contribution: Resists seawater, acidic environments, and chloride ion corrosion; low density reduces weight; aesthetically pleasing surface.
Performance contribution: Acts as the primary channel for current or heat. Alleviates thermal stress, enhances bonding strength, and improves production feasibility.
Performance contribution: High mechanical strength, good processability (such as welding and machining), and a cost-effective base material.
- "External corrosion resistance + medium-high conductivity + internal high strength": The surface is corrosion-resistant, the middle layer is highly efficient for electrical conduction and heat transfer, and the inner layer is strong and capable of bearing loads.
- Excellent electrochemical compatibility: In certain applications (such as cathodic protection), the potential sequence positions of titanium and copper can be carefully designed to achieve specific functions.
- Good thermal expansion matching: Through the transition of the copper layer, the stress caused by the difference in thermal expansion and contraction between the titanium layer and the steel layer is reduced.
- High cost performance: While ensuring high performance on the surface, using inexpensive steel as the base material is much less costly than using all titanium or thick copper materials.
Main purposes and application fields
Ti/Cu/Steel clad material is always aimed at meeting extreme or special multi-functional requirements, mainly applied in:
Specific Application: Special electrolytic electrodes and anode baskets. Used in the electrolysis of corrosive media (such as chlorine-containing environments), the titanium layer resists corrosion, the copper layer ensures uniform current distribution, and the steel layer serves as a framework. They can also be used as conductive structural components in highly corrosive environments.
Specific Application: Hybrid grounding and lightning protection systems for ships. The titanium layer resists seawater corrosion, the copper layer provides a low-resistance grounding path, and the steel layer offers structural support. This is its most classic and important application. Also used in Cathodic Protection Systems as auxiliary anodes or special connectors.
Specific Application: Integrated conductive/structural components for key parts of nuclear power plants. For instance, control rod drive mechanisms or measurement instrument penetration assemblies require titanium to resist high-temperature/high-pressure water, copper for precise/low-loss signal transmission, and steel to withstand mechanical loads.
Specific Application: Special parts requiring lightweight, high strength, high conductivity, and environmental corrosion resistance. Examples include grounding, electromagnetic shielding, or conductive structural units in spacecraft. The copper layer provides electromagnetic pulse protection.
Specific Application: Vacuum chambers or beam components in particle accelerators and synchrotron radiation sources. The titanium layer facilitates achieving ultra-high vacuum, the copper layer is used for cooling or transmitting high-frequency currents, and the steel layer provides the main structure.
