Production Processes
1. Explosive Bonding (Explosive Compositing)
- The two metal sheets to be joined are positioned parallel with a precise stand-off distance.
- A controlled amount of explosive is placed on top.
- Detonation is initiated from one end.
- The enormous energy released by the explosion accelerates the top plate (Compositeder, e.g., titanium) downwards at high velocity.
- This causes a high-velocity, oblique collision with the base plate (e.g., steel), creating localized plastic flow and metallurgical bonding at the interface ("fluid-like behavior").
- This is a solid-state, cold-welding process. The bonded plate can subsequently be hot-rolled to the desired final thickness.
2. Roll Bonding
Heavy Plate Rolling Method:
- The titanium plate and steel plate are assembled in an embedded configuration.
- A suitable intermediate material is placed between them.
- The assembly is sealed under high vacuum using electron beam welding around the edges.
- The sealed assembly is heated and then subjected to strong pressure rolling in a heavy plate mill to achieve the required thickness and bond strength.
Continuous Hot Rolling Method:
- The two plates are assembled with steel strips inserted along the edges.
- The edges are sealed by arc welding in air.
- The assembly is then continuously hot-rolled in a tandem mill to the required thickness before being extracted.
3. Vacuum Welding + Rolling Composite Process
- Titanium-steel composite slab stock is first produced to an initial thickness using vacuum welding techniques.
- This slab is then rolled down to wide, thin-gauge titanium-steel Composite plate using a medium-heavy plate mill.
Performance Characteristics
Excellent Combined Properties
Integrates the advantages of titanium (corrosion resistance, high strength-to-weight ratio, low density) with the properties of the other material (e.g., steel's hardness, aluminum's lightweight nature and workability, composite materials' wear resistance and impact resistance).
High Interfacial Bond Strength
Precise control of process parameters significantly enhances the bond strength between the titanium layer and the substrate. For example, the formation of a continuous thin TiC (Titanium Carbide) layer at the titanium/steel interface can inhibit the formation of brittle Ti-Fe intermetallic compounds. The resulting "pinning effect" further enhances the interfacial bond strength.
Applications

Frequently Asked Questions (FAQ)
Q1. What are Titanium Composite Plates?
Titanium Composite Plates are composite materials formed by bonding a layer of pure titanium or titanium alloy with other metallic (e.g., steel, aluminum) or non-metallic (e.g., carbon fiber, ceramics) materials to integrate their key performance characteristics.
Q2. What are the common types of Titanium Composite Plates?
Common types include Titanium/Titanium, Titanium/Steel, Titanium/Aluminum, Titanium/Carbon Fiber, and Titanium/Ceramic composite plates, custom engineered based on application requirements.
Q3. What production processes are used to manufacture these plates?
They are primarily manufactured using three techniques: Explosive Bonding (high-velocity solid-state impact), Roll Bonding (both Heavy Plate and Continuous Hot Rolling methods), and the Vacuum Welding + Rolling Composite Process.
Q4. What are the main benefits of using Titanium Composite Plates?
They combine the excellent corrosion resistance, high strength-to-weight ratio, and low density of titanium with the structural strength, hardness, cost advantages, or thermal conductivity of the backing substrate.
Q5. In which industries are these composite plates typically applied?
They are widely applied in Aerospace structural components, Chemical Industry vessels/piping (resisting acids/alkalis), Marine Engineering, biocompatible Medical Field devices, and high-performance Automotive components.
Q6. How is high interfacial bond strength ensured during production?
High interfacial bond strength is achieved by precise control of process parameters. For instance, in titanium/steel interfaces, forming a thin Titanium Carbide (TiC) layer inhibits brittle intermetallic compounds, reinforcing the bond via a pinning effect.
