Latest Patents

Dacheng Li holds a patent for his invention titled "Ultrasonic Brazing of Aluminum Alloy and Aluminum Matrix Composite." This method revolutionizes the brazing process by creating a reinforced composite bond without the need for filling welding wire with reinforcement or adding alloy elements to generate a ceramic phase. The technique involves setting a filler metal, introducing ultrasonic vibrations to braze in air, dissolving the base materials, and reintroducing ultrasonic waves. One of the significant advantages of this method is that it allows aluminum brazing to occur at lower temperatures, resulting in shorter brazing periods and reduced costs compared to conventional methods. The strength, service temperature, and dimensional stability of the joints produced are comparable to the base materials.
