19世紀(jì)初，已開始用鉑作為封接材料與軟玻璃封接。1879年，愛迪生(T.Edison)發(fā)明的白熾燈泡以及早期的電子管和X射線管通過玻璃的引出線都用鉑絲。在 1896年法國吉堯姆 (C.E.Guillaume)制成因瓦(Invar)合金(36Ni-Fe)以后,又派生出了代替鉑的46Ni-Fe封接合金，這是早的封接合金。后來進(jìn)一步改進(jìn)這種合金,在表面覆一層薄銅,這種覆銅的42Ni-Fe絲(俗稱杜美絲，Dumet Wire)用作非匹配軟玻璃封接引出線一直使用到70年代。隨著電真空技術(shù)的發(fā)展，出現(xiàn)了熔點(diǎn)高、熱穩(wěn)定性好、熱膨脹系數(shù)更低的硬玻璃。初期采用鉬或鎢與硬玻璃封接。20世紀(jì)30年代出現(xiàn)了與硬玻璃封接的稱為可伐 (Kovar)的Fe-Ni-Co合金;此外,還出現(xiàn)了與軟玻璃封接的Fe-Ni-Cr系、Fe-Cr系、Fe-Ni-Cu系等封接合金。<br /> 第二次世界大戰(zhàn)后，隨著超高頻、大功率電真空器件的發(fā)展，出現(xiàn)了與氧化鋁、氧化鈹?shù)忍沾煞饨拥暮辖?。對膨脹合金提出兼具高?dǎo)熱、高導(dǎo)電、無磁性等物理性能的要求。為此采用了復(fù)合膨脹合金（如覆銅的可伐合金帶材和絲材）、含難熔金屬的封接合金（如Ni-Mo、Ni-Mo-W系等），但用量都不大。<br /></div><p><img

/> KOVAR為含鎳29，鈷17的硬玻璃鐵基封接合金。該合金在20450范圍內(nèi)具有與硬玻璃相近的線膨脹系數(shù)和相應(yīng)的硬玻璃能進(jìn)行有效封接匹配，和較高的居里點(diǎn)以及良好的低溫組織穩(wěn)定性，合金的氧化膜致密，容易焊接和熔接，有良好可塑性，可切削加工，等特點(diǎn)?？煞ズ辖鹨?yàn)楹挸煞?，產(chǎn)品比較耐磨。<br /> 可伐易與鉬組玻璃進(jìn)行配合封接，一般工件表面要求鍍金。<br /> 其狀態(tài)有硬態(tài)和軟態(tài)兩種。<br /> 在一定的溫度范圍內(nèi)，金屬與玻璃的熱膨脹系數(shù)相一致的封接稱為匹配封接。兩者的熱膨脹系數(shù)相差較大的封接稱為非匹配封接。一般采用匹配封接，以保證密封質(zhì)量。</div><p><img

可伐合金合金按規(guī)定的熱處理制度處理后，再經(jīng)-78.5℃冷凍，大于等于4h不應(yīng)出現(xiàn)馬氏體組織。但當(dāng)合金成分不當(dāng)時，在常溫或低溫下將發(fā)生不同程度的奧氏體(γ)向針狀馬氏體(α)轉(zhuǎn)變，相變時伴隨著體積膨脹效應(yīng)。合金的膨脹系數(shù)相應(yīng)增高，致使封接件的內(nèi)應(yīng)力劇增，甚至造成部分損壞。影響合金低溫組織穩(wěn)定性的主要因素是合金的化學(xué)成分。從Fe-Ni-Co三元相圖中可以看到，鎳是穩(wěn)定γ相的主要元素，鎳含量偏高有利于γ相的穩(wěn)定。隨合金總變形率增加其組織越趨向穩(wěn)定。合金成分偏析也可能造成局部區(qū)域的γ→α相變。此外晶粒粗大也會促進(jìn)γ→α相變<br /> 該合金在20-450℃具有與硅硼硬玻璃相近的線膨脹系數(shù)，居里點(diǎn)較高，并有良好的低溫組織穩(wěn)定性。合金的氧化膜致密，能很好地被玻璃浸潤。適用于發(fā)射管、振蕩管、引燃管、晶體管以及管封插頭、繼電器外殼等電真空器件。且不與汞作用，適合在含汞放電的儀表中使用。是電真空器件主要密封結(jié)構(gòu)材料。<br /></div><p><img
