SPF/DB

Superplastic Forming/ Diffusion Bonding

As a pioneer in developing superplastic forming/diffusion bonding (SPF/DB) technology, MTI is leading China’s R&D work on material superplasticity and SPF/DB technology.
In terms of applying SPF/DB into real production, MTI-developed components and structures have been widely used on various aeronautical structures and aero-engine parts. Based on different requirement, our products cover fuselage panel, lid, firewall, aircraft door, airframe structures, aero-engine inlet, state/ rotor blade, wing and appendage, spacecraft fuel tank and other flight vehicle structures.
Regarding fundamental and theoretical research on metallic material superplasticity and superplastic forming, MTI-developed SPF/DB technologies are widely adopted in aeronautical and astronautic industry for processing Ti alloy, Al alloy, Ti-All intermetallic compound and nickel-based superalloy. The benefits of SPF/DB include light-weight manufacture (can make metallic hollow structures), high materials utilization, and manufacture of complex structures.
MTI owns more than 10 sets of SPF/DB equipments with different pressure and working table space and as such, can meet the R&D needs of products with different specifications.

Fields of application:
Forming thin and light-weight integral structures e.g. fuselage panel, lid, aero-engine blade, spacecraft fuel tank, wing and appendage, etc.
