| Research Abstract |
This study describes the experimental results of the ultrasonic welding of ceramics and metals. In comparison to other welding methods, ultrasonic welding has made welding has made welding of various ceramics, such as ZrO2, SiC, and Si3N4, and metals such as aluminum, magnesium, and copper in the atmosphere easier and quicker.
In this study, we accomplish the ultrasonic welding of ceramics and magnesium under the following conditions : amplitude, 30μm, welding pressure, 10MPa, required duration, 1.0 s.
The ultrasonic welding of the ceramics with metals became possible when the condition E=KP^n (E : energy density, P : welding pressure) was satisfied and the welding interface temperature was in the range of 300-400℃. When the ceramics were preheated, welding became possible even in a short time and under a low pressure. The ultrasonic welding material had good weldability even in a high temperature environment. In this environment, it is expected that the oxide and organic films are efficiently removed from the bonded interface by the vibration of an ultrasonic wave for ultrasonic welding.
And, this study gives description of an experimental study of the ultrasonic welding of aluminum and cupper at room temperature and water bath.
