Description

브레이징 접합 도금층을 가진 세라믹체{a plated ceramic with plating seam united drazing}A plated ceramic with plating seam united drazing

본 발명은 금속체와 접합되어 진공기밀을 요하는 제품(마그네트론,서지 어레스터, 진공차단기등)에서 절연과 진공기밀의 역할을 수행하는 세라믹체에 관한 것으로서 이를 좀더 상세히 설명하면 금속체가 접합되는 세라믹체의 접합부에 브레이징 메탈역할을 하는 금속 또는 합금을 단층으로 도금하거나 다층으로 도금하여 금속체를 브레이징 접합할 수 있도록 하므로서 접합체(세라믹체 + 금속체)의 품질향상을 도모하고 이와 동시에 접합 생산성 향상과 비용절감의 효과도 기대할 수 있는 브레이징 접합 메탈층을 가진 세라믹체에 관한 것이다.The present invention relates to a ceramic body which is bonded to a metal body and performs the role of insulation and vacuum tightness in a product (magnetron, surge arrester, vacuum circuit breaker, etc.) that requires a vacuum tightness. It is possible to improve the quality of the bonded body (ceramic body + metal body) by brazing the metal body or alloy that plays the role of brazing metal as single layer or multi-layer plating on the joint part of the body. The present invention relates to a ceramic body having a braze-bonded metal layer that can be expected to reduce cost.

현재까지는 세라믹체에 금속체를 브레이징 접합 하기 위해서는 세라믹체와 금속체 사이에 별도로 제작되는(프레스 성형) 브레이징 메탈판을 개재한 후 개재된 메탈판을 고온에서 녹여 세라믹체 와 금속체가 접합되도록 하였다.Until now, in order to braze a metal body to a ceramic body, the ceramic body and the metal body were joined by melting the interposed metal plate at a high temperature through a brazing metal plate that is manufactured separately (press molding) between the ceramic body and the metal body.

그러나 금속체와 세라믹체를 접합시키는 금속재 메탈판이 약 0.05mm 이하 두께로 압연되는 압연공정과; 일정한 폭으로 되는 금속 롤(Roll)로 만들어지는 절단공정과; 세락믹체와 금속체가 접합되는 접합부의 크기와 형상에 맞도록 성형되는 프레스공정에 의거되어 제작되고 있는데, 이는 메탈판 제작에 많은 인력과 시간, 그리고 많은 비용이 소비되었음은 물론 생산성도 극히 낮은 문제점이 있었고 또한 금속체와 세라믹체를 접합할 때 메탈판을 정확한 위치에 삽입하기 위한 별도의 안내구가 있어야 할 뿐만 아니라 위치가 정해진 메탈판을 브레이징 접합이 완료될 때까지 그 위치를 유지시켜주는 고 내열성 지그(Jig)가 꼭 필요한 문제점이 있었으며 더불어 브레이징 메탈판이 아주 얇기 때문에 취급시에 변형이 쉽게 발생함으로 인하여 금속체와 세라믹체의 접합이 견고하게 되지 않는 문제점도 있었다.However, the rolling step of rolling the metal sheet metal plate for joining the metal body and the ceramic body to a thickness of about 0.05mm or less; A cutting process made of a metal roll having a predetermined width; It is manufactured based on the press process that is formed to fit the size and shape of the junction where the ceramic and metal bodies are joined. This is not only a problem that a lot of manpower, time and money are required to produce the metal plate, but also extremely low productivity. In addition, there must be a separate guide for inserting the metal plate in the correct position when joining the metal body and the ceramic body as well as high heat resistance to maintain the position of the positioned metal plate until the brazing bonding is completed. Jig (Jig) was a necessary problem, and because the brazing metal plate is very thin, there was also a problem that the bonding of the metal body and the ceramic body is not firm because the deformation occurs easily during handling.

이를 해결하기 위해 세라믹체의 금속체의 접합부에 금속재 분말을 도포하는 것이 개발되었으나 이 또한 정확한 두께로 도포하는 작업이 매우 난이 하였고 또 정밀한 도포를 위해 사용되는 설비 및 치구에 많은 비용이 소비되는 경제적인 부담이 있었으며, 또한 도포 건조후에 취급시 또는 브레이징 접합시에 도포된 부분이 쉽게 벗겨지는 문제점이 있었다.In order to solve this problem, it has been developed to apply metal powder to the joint of the metal body of the ceramic body, but it is also very difficult to apply the exact thickness and the cost is expensive for the equipment and fixtures used for precise application. There was a burden of phosphorus, and also there was a problem that the applied part was easily peeled off during handling or brazing bonding after application drying.

본 발명은 상기에서 설명한 바와 같은 폐단들을 한꺼번에 해결하기 위하여세라믹체의 금속체 접합부에 금속재를 도금하여 그 도금층이 브레이징 접합에 필요한 메탈판 역할을 하도록 하므로서 금속체와 세라믹체의 브레이징 접합을 보다 용이하고 저렴하게 할 수 있도록 한 것에 주안점을 두고 그 기술적 과제로서 완성한 것이다.The present invention is to facilitate the brazing joining of the metal body and the ceramic body by plating the metal material on the metal joining portion of the ceramic body in order to solve the closed ends as described above at the same time so that the plating layer acts as a metal plate necessary for brazing bonding. The main focus was on making it affordable, and it was completed as a technical task.

금속체(2)와 접합되어 진공기밀을 요하는 제품(마그네트론, 서지 어레스터, 진공차단기 등)에서 절연과 진공기밀의 역할을 수행하는 세라믹체(1)에 있어서, 세라믹체(1)의 금속체(2) 브레이징 접합부(101)에 금속재를 단층 또는 다층으로 도금하여 도금층(100)을 형성케 하여서된 것이고, 또한 상기 세라믹체(1)의 접합부(101)에 도금되는 단층 도금층(100)의 금속재는 은 또는 구리와 은의 합금으로 하거나 상기 세라믹체(1)의 접합부(101)에 도금되는 도금층을 구리와 은의 복합층으로 이루어지게 한 것이다.In the ceramic body 1, which is bonded to the metal body 2 and performs the role of insulation and vacuum tightness in a product (magnetron, surge arrester, vacuum circuit breaker, etc.) that requires vacuum sealing, the metal of the ceramic body 1 The body 2 is formed by plating a metal material in a single layer or a multilayer on the brazing junction portion 101 to form the plating layer 100, and also of the single layer plating layer 100 plated on the junction portion 101 of the ceramic body 1. The metal material is made of silver or an alloy of copper and silver, or a plating layer to be plated on the junction portion 101 of the ceramic body 1 by a composite layer of copper and silver.

이와 같이된 본 발명은 금속체(2)가 브레이징 접합되는 세라믹체(1)의 접합부(101)에 브레이징 접합 온도(약 760℃-1150℃)에서 녹는 금속 또는 합금이 단층 내지 다층으로 도금되어 있으므로 금속체(2)를 세라믹체(1)의 접합부(101)에 밀착시킨 상태에서 고온의 수소분위기로 또는 고진공로에 넣으면 세라믹체(1)와 금속체(2)가 접합되게 된다.In the present invention as described above, since the metal or alloy melting at the brazing bonding temperature (about 760 ° C. to 1150 ° C.) is plated in a single layer or multiple layers on the junction portion 101 of the ceramic body 1 to which the metal body 2 is brazed. When the metal body 2 is brought into close contact with the junction portion 101 of the ceramic body 1 in a high-temperature hydrogen atmosphere or in a high vacuum furnace, the ceramic body 1 and the metal body 2 are joined.

즉, 세라믹체(1)의 접합부(101)에 형성되는 단층 또는 복층의 도금층(100)이 브레이징 접합에 필요한 메탈판 역할을 하게되는 것이다.That is, the plating layer 100 of the single layer or the multiple layer formed in the junction portion 101 of the ceramic body 1 serves as a metal plate required for brazing bonding.

따라서 본 발명은 상기한 바와 같이 세라믹체(1)의 접합부(101)에 형성되는 도금층(100)을 이용하여 금속체(2)와 세라믹체(1)를 브레이징 접합하므로 종래와 같이 브레이징 접합 메탈판을 제작하는데 소비되는 비용과 시간 그리고 인력의 낭비를 대폭적으로 줄일 수 있는 효과가 있으므로 원가절감과 생산성 향상을 도모할 수 있는 잇점이 있으며, 또한 금속체(2)와 세라믹체(1)의 정확한 접합을 위한 각종 설비들도 대폭 감소되기 때문에 이 역시 비용절감의 효과를 가져올 뿐만 아니라 금속체(2)의 접합이 세라믹체(1)의 자체에 형성되는 브레이징 접합 메탈층(도금층)에 의거되므로 금속체(2)와 세라믹체(1)의 접합 불량율이 극히 낮아짐은 물론 접합부분이 깔끔하고 견고하게 되어 제품의 신뢰성과 품질을 향상시킬 수 있게 되는 등 상당히 기대되는 효과가 다대한 발명이다.Therefore, the present invention braze-bonds the metal body 2 and the ceramic body 1 using the plating layer 100 formed on the junction portion 101 of the ceramic body 1 as described above. The cost, time, and manpower waste required to manufacture the material can be drastically reduced, resulting in cost reduction and productivity improvement. Also, accurate bonding of the metal body (2) and the ceramic body (1) Since various equipments for metals are also greatly reduced, this also brings cost saving effect, and since the bonding of the metal body 2 is based on the brazing bonding metal layer (plating layer) formed on the ceramic body 1 itself, the metal body The failure rate of bonding between (2) and the ceramic body (1) is extremely low, and the joining part is neat and solid, so that the reliability and quality of the product can be improved.
