Description
본 발명은 양극산화 표면을 포함하는 초전도 박막선재 및 그 제조방법에 관한 것으로, 더욱 상세하게는 초전도 박막선재을 알루미늄 또는 알루미늄 합금의 재질로 용융도금한 후, 양극산화시켜 형성된 양극산화피막을 통해권선 시, 초전도 박막선재 간의 절연특성 및 고열전도도 특성을 가능하게 하는 양극산화 표면을 포함하는 초전도 박막선재 및 그 제조방법에 관한 것이다.The present invention relates to a superconducting thin film wire having an anodized surface and a method for manufacturing the same, and more specifically, after superconducting the thin film of superconducting with an aluminum or aluminum alloy material, and then winding through an anodized film formed by anodizing. , It relates to a superconducting thin film wire and a method for manufacturing the superconducting thin film wire including an anodized surface to enable the insulating properties and high thermal conductivity properties.
초전도층을 포함하는 초전도 박막선재는 임계 온도 이하에서 저항이 0인 상태로 많은 전류를 통전할 수 있다. 이러한 이점 때문에 손실 없이 고밀도의 전류 공급이나 송전을 필요로 하는 케이블, 모터, 변압기, 한류기 등의 고온초전도 전력기기와 초전도 응용기기의 핵심 소재로 적용 연구가 활발히 진행되고 있다. 이러한 초전도 박막선재 중 2세대 고온 초전도 선재는 이축배향된 금속기판 위에 여러 종류의 구성 재료들을 결정축에 따라서 에피택셜 성장(Epitaxial growth)을 통해 제조되며, 이러한 박막형 고온초전도 선재를 코티드 컨덕터(Coatedconductor)라고 한다. 이러한 초전도 박막선재는 일반적으로 니켈합금이나 스테인레스강 등과 같은 금속기판의 상부에 복수의 완충층을 코팅하고, 완충층의 상부에 초전도층, 초전도층의 상부에는 초전도층을 보호하기 위한 은 보호층을 코팅하며, 최종적으로 구리 안정화재를 전해도금하여 제조한다. 구리 안정화층은 초전도층이 갑자기 초전도 특성을 상실할 때(이를 Quenching 이라고 함) 초전도층에 흐르던 전류를 바이패스(Bypass)시키는 역할을 담당한다.A superconducting thin film wire including a superconducting layer can conduct a lot of current with a resistance of 0 under a critical temperature. Because of these advantages, research on application as a core material for high-temperature superconducting power equipment and superconducting applications such as cables, motors, transformers, and current limiters that require high-density current supply or transmission without loss has been actively conducted. Among these superconducting thin-film wires, the second-generation high-temperature superconducting wire is manufactured by epitaxial growth of various types of constituent materials on a biaxially oriented metal substrate along a crystal axis, and these thin-film high-temperature superconducting wires are coated conductors. It is said. These superconducting thin film wires are generally coated with a plurality of buffer layers on top of a metal substrate such as nickel alloy or stainless steel, a superconducting layer on top of the buffer layer, and a silver protective layer for protecting the superconducting layer on top of the superconducting layer, , Finally, the copper stabilizer is electrolytically plated. The copper stabilizer layer plays a role of bypassing the current flowing through the superconducting layer when the superconducting layer suddenly loses superconducting properties (this is called quenching).
한편 초전도 박막선재를 코일 등으로 권선 시 선간 전기적인 절연을 위해 종래에는 켑톤(Kapton) 필름과 같은 절연재를 코와인딩(Co-winding) 하는데, 켑톤 필름을 박막선재들 사이에 삽입하여 박막선재 간 전기적으로 절연되도록 한다. 이때 켑톤 필름 등과 같은 종래의 절연재는 열전달특성이 매우 나빠 초전도 전력기기를 냉각시켜주는 냉각 장치가 비대하게 설계된다. 뿐만 아니라 켑톤 필름은 두께가 약 25 내지 50㎛에 불과하고 고분자 재질이기 때문에, 권선 시 선재의 응력보강의 이점은 전혀 기대할 수 없다. 또한, 박막 선재의 경우 두께가 01mm에 불과하여 기계적 강도가 매우 약해 취급이 까다로워 작업자의 취급 부주의시 초전도 특성 저하가 발생할 소지가 크고, 전류 인가시 발생하는 유도 전자기력에 의해 초전도 성능기 저하되기도 하기 때문에 권선 코일의 응력 보강은 응용적인 측면에서 매우 중요하다. 따라서 종래의 단점까지 극복할 수 있는 새로운 기술 적용을 모색하고자 한다.On the other hand, when winding a superconducting thin film wire with a coil or the like, conventionally, an insulating material such as a Kapton film is co-winded for electrical insulation between wires. To be insulated. At this time, a conventional insulating material such as a hempton film has a very poor heat transfer characteristic, and a cooling device that cools a superconducting power device is designed to be enlarged. In addition, since the Phenton film has a thickness of only about 25 to 50 µm and is a polymer material, the advantage of stress reinforcement of the wire during winding cannot be expected at all. In addition, since the thickness of the thin film wire is only 01 mm, the mechanical strength is very weak, and handling is difficult, so there is a great possibility of deterioration of superconducting properties when handling is inadvertent, and the superconducting performance is also deteriorated by the induced electromagnetic force generated when current is applied. Stress reinforcement of the winding coil is very important in terms of application. Therefore, it is intended to find a new technology application that can overcome the conventional disadvantages.

It is preferable to form an anodized film.
