Latest Patents

Zhongning Guo holds a patent for a groundbreaking method titled "Method of laser joining of dissimilar materials with ultrasonic aid." This new ultrasonic aided laser joining method (UAL) is designed to bond dissimilar materials effectively. The UAL method is capable of eliminating laser-induced bubbles at the bonding faces, which significantly improves joint strength compared to the conventional laser-assisted metal and plastic joining method (LAMP). Experimental results demonstrate that when ultrasonic vibration is employed during laser joining, the joint strength, measured in terms of failure load, is significantly increased. In contrast to LAMP joined specimens, where fractures typically occur at the metal-plastic interface, UAL joined specimens experience fractures in the parent plastic part. This improvement in joint strength is primarily attributed to the elimination of pores in the resolidified plastic, along with enhanced chemical bonding between the plastic and metal parts, as supported by XPS results.
