Feature of Titanium steel composite plates

Titanium Layer Thickness: The thickness of the titanium layer, typically ranging from 0.1mm to a few millimeters, is selected based on the required corrosion protection and surface properties.

Substrat d'acer: The steel substrate can be mild steel, acer inoxidable, or high-strength steel, chosen for its mechanical strength, cost, or specific application requirements. The thickness of the steel layer is determined by structural needs.

Bonding Technology: The bonding method between titanium and steel layers is crucial, often involving explosive bonding, unió de rotlles, or diffusion bonding, each offering distinct advantages in terms of bond strength, uniformity, and process efficiency.

Acabat superficial: The titanium surface can be finished in various ways, including polished, blasted, or coated, to enhance aesthetics or specific functional properties such as reducing friction or increasing biocompatibility.

Dimensional Stability: Composite plates must exhibit minimal distortion during processing and in service, which is influenced by material selection, mètode d'enllaç, and thermal treatments.

Resistència a la corrosió: The titanium layer provides exceptional resistance to corrosion, protecting the underlying steel in harsh environments. Specific testing (p. ex., salt spray test) is often conducted to quantify this property.

Propietats mecàniques: The composite’s tensile strength, yield strength, and toughness are determined by the properties of both titanium and steel layers and their interaction. These are critical for load-bearing applications.

Formability and Machinability: The composite’s ability to be formed or machined into complex shapes is influenced by the composite’s thickness, layer structure, and the choice of steel substrate.

Tractament tèrmic: Post-bond heat treatments may be necessary to relieve residual stresses, improve bond strength, or adjust the microstructure for optimized performance.

Weight-to-Strength Ratio: The combination of titanium and steel aims to achieve a favorable balance between weight and strength, making these plates suitable for applications where weight reduction is crucial.

Non-Destructive Testing (NDT): Techniques like ultrasonic testing, radiography, or eddy current testing are employed to inspect the bond quality and detect any defects without damaging the composite.
