본 발명은 세라믹 소재와 스테인레스강 접합소재에 관한 것으로, 특히 PZT-세라믹 소재와 스테인레스강 합금의 두 모재를 접합하는 용가제로서 주석(Sn)과, 칼슘(Ca)과, 납(Pb)의 혼합물질을 적용하여 모재의 접합을 최적화시키도록 한 것을 특징으로 하는 세라믹 소재와 스테인레스강 접합소재에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceramic material and a stainless steel bonded material, and in particular, a mixture of tin (Sn), calcium (Ca), and lead (Pb) as a solubilizer for joining two base materials of a PZT-ceramic material and a stainless steel alloy. The present invention relates to a ceramic material and a stainless steel bonding material, characterized in that the material is applied to optimize the bonding of the base material.
일반적인 이종 금속을 접합시에 접착제로서 용가재 금속을 사용하며, 용가재 금속을 이용한 접합방식에서는 인(In)과 납(Pb)을 사용하거나 접착제를 사용하여 두 모재를 접합하였다.In general, a dissimilar metal is used as an adhesive for bonding a filler metal, and in the bonding method using a filler metal, phosphorus (In) and lead (Pb) are used or two base materials are bonded by using an adhesive.
기본적으로 인이나 납과 같은 용가재는 금속계열에는 잘 접착되지만 PZT(티탄산지루콘산납)-세라믹소재에는 잘 접착되지 않는 성질을 가지고 있어서 접착성이 우수하지 못하다.Basically, filler metals such as phosphorus and lead are well adhered to metal series, but are not well adhered to PZT (ceramic titanate titanate) -ceramic materials.
또한, 일반적인 접착제를 사용하게 되면 상온에서는 일정한 강도를 유지하나 고온이나 저온에서 접착제 성질의 변화가 발생하여 일정한 수준의 접착상태를 유지하기가 어렵다.In addition, when a general adhesive is used, it maintains a constant strength at room temperature, but changes in adhesive properties occur at high or low temperatures, making it difficult to maintain a constant level of adhesion.
또한, 통상 일반적인 가열로를 사용하여 용가재를 녹여서 두 모재를 부착시키는 것이 널리 사용되는 방법이지만 대기 상태에서는 공기내부의 여러불질들과 용가재가 결합하게 되어 결합력을 떨어뜨리므로 진공가열로의 사용이 필요하고, 적절한 온도구간이 정의되어야 좋은 결합력을 얻을 수 있다.In addition, it is common to use a common heating furnace to melt the filler metal and attach the two base materials.However, in the air state, the use of a vacuum heating furnace is necessary because various inflames and the filler material in the air are combined to reduce the bonding strength. In addition, a proper temperature range must be defined to obtain good bonding force.

도 1은 본 발명의 개념도로서, 도시한 바와 같이, PZT-세라믹 소재(100)와, 스테인레스강 합금(200)과, 상기 두 모재를 결합하는 혼합 용가제(300)로 이루어지며, 상기 혼합 용가제(300)는 주석(Sn)과, 칼슘(Ca)과, 납(Pb)으로 이루어진다.1 is a conceptual diagram of the present invention, as shown, consisting of a PZT-
또한, 본 발명은 주석(Sn)과, 칼슘(Ca)과, 납(Pb)의 혼합 용가제(300) 비율을 각각 5 - 10중량%, 15 - 20중량%, 70 - 80중량%로 조합된 용가제를 사용한다.In addition, the present invention combines the ratio of the mixed
그리고, 용가제(300)가 혼합되면 세라믹 소재(100)와 스테인레스강 합금(200) 사이에 도포하고, 도포가 완료되면 모재(100, 200)를 진공가열에 투입하여 진공가열하는 공정을 진행하는바, 진공가열 공정은 초기 진공도 1 * 10-3torr 이하 를 계속 유지하며 30분당 섭씨 50도씩 올리면서 가열하여 2시간 30분에 걸처 섭씨 250도 까지 온도를 올린다.When the
또한, 섭씨 250도에서 주석, 칼슘, 납 혼합 용가제가 충분히 녹은 상태로 두 모재를 잘 결합시키기 위하여 1 * 10-3torr의 진공도를 유지하면서 약 30 - 60분 동안 섭씨 250도의 온도를 유지시키고, 이후 진공 가열로를 끄고 자연 냉각시켜 두 모재(100, 200)의 결합을 완성한다.In addition, at 250 degrees Celsius, the tin, calcium, and lead mixed solvents are sufficiently dissolved to maintain a temperature of 250 degrees Celsius for about 30 to 60 minutes while maintaining a vacuum degree of 1 * 10 -3 torr to bond the two base materials well. Then turn off the vacuum furnace and naturally cooled to complete the combination of the two base materials (100, 200).
접합의 신뢰성 및 접착상태 검증은 Q-factor를 측정하여 반영하였다.The reliability and adhesion state verification of the joint was reflected by measuring the Q-factor.
PZT(티탄산지루콘산납)-세라믹소재와 SUS합금 모재를 접합하여 PZT에 전압을 인가하여 공진 주파수를 공진주파수 최대치의 0.707배 되는 양쪽 지점의 주파수의 차로 나눈 값으로 공진주파수를 측정한 Q-factor 대역폭을 측정하여 구하였다.PZT (lead zirconate titanate) -ceramic material and SUS alloy base material bonded together to apply voltage to PZT, and the resonance frequency was measured by dividing the resonant frequency by the difference of the frequency at both points which is 0.707 times the maximum resonant frequency. The bandwidth was measured and obtained.
참고로, 공진에서의 Q(Quality factor)는 주파수 선택 특성품질을 의미하며, 공진주파수점에서 양쪽으로 3dB, 즉 반으로 감쇄되는 지점의 주파수간의 차이를 소위 3dB 대역폭이라고 하는데, 공진주파수를 3dB 대역폭으로 나눈 것이 바로 Q값이다. 즉 공진특성이 샤프할수록 3dB 대역폭은 좁아질 것이고, 결국 Q값은 커지게 된다.For reference, Q (Quality factor) in resonance refers to the frequency selective characteristic quality, and the difference between the frequencies of 3dB, i.e., attenuated in half at the resonance frequency point is called a 3dB bandwidth, and the resonance frequency is referred to as a 3dB bandwidth. Divided by is the Q value. In other words, the sharper the resonance characteristic, the narrower the 3dB bandwidth becomes, and eventually the Q value becomes larger.
공진이란게 결국 특정 주파수의 선택특성을 말하는 것이기 때문에, 얼마나 샤프하게 주파수를 선택해낼 수 있느냐를 의미하는 지표가 결국 Q값인 것이며, Q값은 대체로 높아야 좋은 경우가 많다.Since resonance refers to the selection characteristic of a specific frequency, the index indicating how sharply the frequency can be selected is the Q value.
fr : 공진주파수, fH : 공진주파수의 상위 0.707배, fL : 공진주파수의 하위 0.707배f r : resonance frequency, f H : upper 0.707 times of resonant frequency, f L : lower 0.707 times of resonant frequency
기존의 여러 종류의 접착제와 용가재 Sn, Ca, Pb의 비율을 바꿔 가면서 온도범위 -50 ∼ 70℃에서 Q-factor 대역폭을 측정하였다. The Q-factor bandwidth was measured in the temperature range of -50 ~ 70 ℃ by changing the ratio of various kinds of adhesives and filler materials Sn, Ca, Pb.
측정한 값은 용가재 Sn, Ca, Pb 의 구성 비율이 각각 5-10중량%, 15-20%, 70-80% 로 조합된 접합용 용가재에서 가장 큰 Q-factor 값을 나타내었다. The measured values showed the largest Q-factor values in the joining filler metal in which the composition ratios of the filler metals Sn, Ca, and Pb were 5-10% by weight, 15-20%, and 70-80%, respectively.
이는 두 모재의 접착상태가 단단하게 접합 될수록 Q-factor 값이 증가 하므로 용가재 Sn, Ca, Pb 의 구성 비율 5-10%, 15-20%, 70-80% 로 조합된 접합용 용가재가 어떠한 접합재료 보다 우수하다는 것을 증명하는 것이다.This is because the Q-factor value increases as the bonding state of the two substrates is firmly bonded. It proves to be superior to the material.
