1107 Failure mode and strength of metallic glass micro gear : Development of performance tester for micro gear

Abstract

Nowadays, precision instruments play a vital role in performing surgery inside of a human body. The instruments require micro motor which comprises of several micogears, and producing those complicated tooth shy of microgear is a huge challenge for gear engineers. Using bulk metallic glass to fabricate microgear could reduce the difficulties faced in manufacturing process and it is also expected to extend gear life cycle. This paper deals with developing a metallic glass micro gear performance tester through evaluation experiments of its basic strength and failure mode.
