저항용접기 전극용 동-지르코늠-세리움-란탄-니오디미움 프라세오디미움 합금의 제조방법Method for producing copper-zirconium-cerium-lanthanum-nidiumdium praseodymium alloys for resistance welder electrodes

본 발명은 저항용접기용 전극재인 동(Cu) -지르코늄(Zr) -세리움(Ce) -란탄(La) -니오디미움(Nd) -프라세오디미움(pr) 금의 제조방법에 관한 것이다.The present invention relates to a method for producing a copper (Cu)-zirconium (Zr)-cerium (Ce)-lanthanum (La)-nidium (Nd)-prasedium (pr) gold as an electrode material for resistance welding. .

종래의 경우는 크롬(Cr)과 지르코늄(Zr)의 총함량을 1%(중량백분률) 전후 함유한 동(Cu)-크롬(Cr) 2원합금이나 동(Cu)-크롬(Cr)-지르코늄(Zr) 3원합금을 가공과 열처리로써 도전률을 순동의 80% 정도 유지하면서 강도는 순동의 2∼3배 정도까지 향상시킬 수 있게하여, 공업적으로 강판의 저항용접 및 스포트용접 전극재로서 사용하고 있다.In the conventional case, a copper (Cu) -chromium (Cr) binary alloy or a copper (Cu) -chromium (Cr)-containing a total content of chromium (Cr) and zirconium (Zr) before and after 1% (weight percent) By processing and heat-treating zirconium (Zr) ternary alloy, the conductivity can be improved to about 2 to 3 times that of pure copper while maintaining the electrical conductivity of about 80% of pure copper. It is used as.

동(Cu)-지르코늄(Zr) 2원합금의 상태도를 보면, 용체화 처리하는 부근의 온도인 1,000℃ 정도로 가열하면 지르코늄(Zr)은 0.15% 정도가 고용되며, 이를 시효처리하면 미세한 지르코늄(Zr) 입자들이 석출하여 기지를 강화시키나 450℃ 이상의 고온에서는 경도가 급격히 저하된다.In the state diagram of the copper (Cu) -zirconium (Zr) binary alloy, zirconium (Zr) is dissolved in about 0.15% when heated to about 1,000 ° C, which is the temperature near the solution treatment, and when it is aged, fine zirconium (Zr) is employed. ) Particles precipitate to reinforce the matrix, but the hardness decreases rapidly at a temperature higher than 450 ° C.

이러한 관점에서, 동(Cu)-지르코늄(Zr) 2원합금은 저항용접 및 점(스포트) 용접용 전극으로 사용되는 경우에, 순간적으로 높은 가압력하에서 대전류가 통하여 높은 저항열이 발생하는 상황이므로 접촉부의 소모가 크며, 피접물에 들러붙는 소위 스티킹(sticking) 현상이 종종 나타나는 경우가 있다.From this point of view, the copper-zirconium (Zr) binary alloy is used for resistance welding and spot (spot) welding, which is a situation where high resistance heat is generated through high current under instantaneous high pressing force. The consumption of is large, and the so-called sticking phenomenon which adheres to a to-be-adhered object often appears.

이러한 문제점들은 전극의 수명을 저해하며 용접부를 깨끗하지 못하게하고 한편, 동(Cu)-지르코늄(Zr) 2원합금에 대하여 제반의 특성을 개선하기 위해, 시효경화성이 높은 Al, Si, Be, Co 등과 같은 원소들을 첨가하는 경우에, 그 원소의 종류와 첨가량의 증가에 따라 경도는 어느 정도 향상시킬 수 있으나 도전률은 크게 저해되는 경우가 일반적이어서 적당하지 못하다.These problems hinder the life of the electrode and make the weld unclean, while improving the characteristics of the copper-zirconium (Zr) binary alloy in order to improve the characteristics of Al, Si, Be, Co. In the case of adding elements such as the like, the hardness can be improved to some extent with the increase in the kind and the amount of the element, but the conductivity is largely impaired.

그리고 이미 알려진 일본특개소 63-38543호는 냉각가공후에 용체화열처리하는 방법이고 본 발명은 용체화 처리후 냉각가공을 하며 일본특개소 63-93837호는 전자기기 리드용 동합금의 제조법이나 본 발명은 저항용접기 전극용 동합금의 제조방법과는 기술개념이 상이하다.In addition, Japanese Patent Application Laid-Open No. 63-38543 is a method for heat treatment after solution cooling, and the present invention is a cooling process after solution treatment. Japanese Patent Application Laid-Open No. 63-93837 is a method for manufacturing a copper alloy for electronic device lead or the present invention. The technical concept is different from the manufacturing method of the copper alloy for resistance welder electrodes.

이러한 문제점을 고려하여 본 발명에서는, 동(Cu)-지르코늄(Zr) 2원합금 중에 고용할 수 있고, 주성분인 동(Cu)과 화합물을 형성할 수 있는 원소들인 세리움(Ce), 란탄(La), 니오디미움(Nd) 및 프라세오디미움(Pr)을 첨가하여 용해 후 주괴를 제조하고, 이를 가공열처리하여 높은 온도에서도 미세하고 안정한 여러가지 석출물들이 기지 전반에 생성하여 재료의 특성을 개선할 수 있게 하였다.In view of the above problems, in the present invention, elements such as cerium (Ce) and lanthanum (Cu), which can be dissolved in a copper (Zr) binary alloy and can form compounds with copper (Cu) as a main component, La), Nidium (Nd) and Praseodymium (Pr) are added to produce ingot after dissolution and processing heat treatment to produce various precipitates that are fine and stable even at high temperature throughout the base to improve the properties of the material. I could do it.

그리고 특히 세리움(Ce) 및 란탄(La)의 첨가는 합금용에 과정에서 탈산제로서의 효과도 매우 크다.In particular, the addition of cerium (Ce) and lanthanum (La) is also very effective as a deoxidizer in the process for the alloy.

즉, 본 발명은 높은 온도에서도 재료의 특성을 안정적으로 유지시키고, 용접시 스티킹 현상을 현저히 줄이며, 용접수명을 개선시킬 수 있는 방법으로서, 실시예의 결과를 보면 525℃의 고온시효 후에도 경도와 도전률은 각각 HRB 70∼80, LACS 80∼89%를 유지하며 용접특성이 개선되었다.That is, the present invention is a method that can stably maintain the properties of the material even at high temperature, significantly reduce the sticking phenomenon during welding, and improve the welding life. The welding rate was improved with HRB of 70-80 and LACS of 80-89%, respectively.

이하 그 제조공정을 실시예에 의거 상세히 설명하면 다음과 같다.Hereinafter, the manufacturing process will be described in detail with reference to Examples.

위의 제1실시예에 따라 제조한 실시예의 결과를 제시하면 다음과 같다.Referring to the results of the embodiment prepared according to the first embodiment as follows.

실시예에서 합금의 종류와 각각의 성분은 다음의 표 1에서와 같으며, 두께 70mm의 주괴로 용해주조하였다.In Example, the type of alloy and each component are as shown in Table 1 below, and were cast by ingot with a thickness of 70mm.

상기를 880℃에서 두께 10mm까지 7S(약 85%)의 가공도로써 열간압연하고, 960℃에서 1시간 유지후 수냉함으로써 용체화처리한 것을 상온에서 두꼐 1.5mm까지 85% 냉간압연한 후, 425℃,450℃,475℃,500℃,525℃ 및 550℃에서 각각 3시간 유지후 수냉시켜 시효경화 열처리하였다.After hot rolling at a processing degree of 7S (about 85%) up to a thickness of 10 mm at 880 ° C, and maintaining the solution at 960 ° C. for 1 hour, the solution solution was cold-rolled to 85 mm at 85 ° C. at a temperature of 425 ° C., and then 425 After aging for 3 hours at 450 ° C., 475 ° C., 500 ° C., 525 ° C. and 550 ° C., the solution was cooled by water and subjected to age hardening.

그 결과는 다음의 표 2에서와 같으며, 표 2중에는 같은 공정을 거친 기존의 동(Cu)-크롬(Cr) 2원합금 2원합금의 경우도 제시하였다.The results are shown in Table 2 below. Table 2 also shows the case of the conventional copper (Cu) -chromium (Cr) binary alloy binary alloy.
