초록

본 논문에서는 알칼리성 또는 산성을 띠는 특정 용액 내에서 전기분해 원리를 이용하여 금속 표면을 산화시켜 절연피막을 형성하는 장치를 개발한다. 기존에는 주로 양극에만 펄스 형태로 전압을 인가하는 단극성(unipolar) 방식이지만 본 논문에서는 H-브리지를 이용하여 양극에 양(+)전압과 음(-)전압을 번갈아 가면서 전압을 공급하는 양극성(bipolar) 장치를 제작하였으며, 금속 시편의 특성에 맞는 다양한 전기적인 조건을 가지고 산화피막을 형성할 수 있는 장치를 개발하였다. 공급전류 가변은 PWM 변조를 이용하였으며, (+)와 (-)의 극성변화는 H-브리지를 이용하여 양극성 펄스전압을 공급할 수 있도록 하였다. 그 결과로써 단극성보다 균일한 기공을 갖는 피막이 형성되었다.

In this paper, alkaline or acidic solution, in particular the principle of electrolysis to oxidize the metal surface to form a device isolation film is developed. In the past, mainly in the form of pulse voltage is applied to the anode only a unipolar method, but in this paper by using the H-bridge to the amount of the positive (+) voltage and the negative supply voltage, alternating voltage polarity devices were fabricated according to the characteristics of metal specimens with different electrical conditions to form an oxide film on the device was developed. Supply current variable was used for the PWM modulation, (+) and (-) polarity change of the H-bridge bipolar pulse voltage to supply the was that. As a result, a more uniform pores with unipolar film was formed.
