碩士 === 國立中山大學 === 機械與機電工程學系研究所 === 90 === Abstract
With the development of new technology and the stringent requirement for the international environmental regulation, the silver-oxide cadmium composites with the best contact performance will be prohibited due to the anxiety to cause cancer. Therefore, this study intends to develop a new contact materials with the best contact performance and cost.
This study intends to use the silver powder (2~4μm) as the major component, and the alumina ceramic powders (0.5μm) as the minor component. The self-development mixer is used to uniformly mix silver powder with alumina powder, and then the powder metallurgy is used to make the electric contacts. Under the supply voltage and current, as well as the mixing conditions, the contact erosion amount, the arc energy, and the contact resistance are measured to investigate the erosion mechanism. Results show that the electric contact with 4%wt alumina ceramic powder has the best performance. Furthermore, the new electric contacts of silver base alumina composite material appear the acceptable performance compared with the commercial electric contacts.
