Latest Patents
Zhiwu Xu holds a patent for a method titled "Ultrasonic brazing of aluminum alloy and aluminum matrix composite." This method involves ultrasonic brazing of metal matrix composites, which creates a reinforced composite bond without the need for filling welding wire with reinforcement or adding alloy elements to generate a ceramic phase. The process includes several steps: setting a filler metal, introducing ultrasonic vibration to braze in air, dissolving the base materials, and reintroducing ultrasonic waves. This technique allows for aluminum brazing at low temperatures, resulting in shorter brazing times and reduced costs compared to conventional methods. The strength, service temperature, and dimensional stability of the joint are comparable to the base material.
