Nitinol 형상기억합금 전해가공의 전해액 영향분석 = An Evaluation of electrolyte effect on electrochemical macnining for nitinol shape memory alloy

다국어 초록 (Multilingual Abstract)

Electro-chemical Machining, the anodic dissolution process is able to achieve wanted a sharp shape and high quality surface without contact with workpiece and low heat effect using electrochemical reaction between anode and cathode. In hence this process useful to apply micro structure. A shape memory alloy for micro-structure and micro industrial technique, Nitinol is composed of approximately 55% Nikel and 45% Titanium by weight. This material is able to function as to transform specific shape from a certain deformation when the alloy is heated. Therefore Nitinol is used for several industries such as a medical industry, a aerospace, electrical application on a part of micro structure.
In this paper, effect of electrolyte is studied on electrochemical machining for Nitinol shape memory alloy, copper is used for electrode, diameter and depth are measured as a extent of processing using optical microscope.
