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(guó)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)忍沾煞饨拥暮辖稹?duì)膨脹合金提出兼具高導(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

定義：當(dāng)含有細(xì)微縫隙的物體與液體接觸時(shí)，在浸潤(rùn)情況下液體沿縫隙上升或滲入，在不浸潤(rùn)情況下液體沿縫隙下降的現(xiàn)象。在浸潤(rùn)情況下，縫隙越細(xì)，液體上升越高。就是指液體在細(xì)管狀物體的內(nèi)側(cè)因?yàn)閮?nèi)聚力以及附著力的差異，克服地心引力而向上升。<br /> 介紹<br /> 毛細(xì)現(xiàn)象(又稱毛細(xì)管作用)，是指液體在細(xì)管狀物體內(nèi)側(cè)，由于內(nèi)聚力與附著力的差異，克服地心引力而上升或下降的現(xiàn)象。<br /> 含有細(xì)微孔隙的物體與液體接觸時(shí)，使該液體沿孔隙上升或下降的現(xiàn)象。當(dāng)液體和固體(管壁)之間的附著力大于液體本身內(nèi)聚力時(shí)，就會(huì)產(chǎn)生毛細(xì)現(xiàn)象（上升）；反之，當(dāng)液體和固體(管壁)之間附著力小于液體本身內(nèi)聚力時(shí)，就會(huì)產(chǎn)生毛細(xì)現(xiàn)象（下降）。液體在垂直的細(xì)管中時(shí)液面呈凹或凸?fàn)?、以及多孔材質(zhì)物體能吸收液體皆為此現(xiàn)象所致。毛細(xì)管作用的出現(xiàn)是由于水具有黏性 — 水分子互相黏著附在其他物體上的特性，這些物體可以是玻璃、布、器官組織或土壤。而水銀因其原子之間的內(nèi)聚力極強(qiáng)，所以發(fā)生毛細(xì)現(xiàn)象（下降）。<br /> 越細(xì)的毛細(xì)管吸水所受的氣壓影響越不明顯，所以越細(xì)的毛細(xì)管在垂直于水面的情況下吸水程度越強(qiáng)。</div><p><img

class="khcont2">可伐合金的生產(chǎn)工藝的相關(guān)說明，<br /> 可伐合金的冶煉應(yīng)根據(jù)合金的化學(xué)成分，特別是碳、磷、硫以及為提高合金性能加入的微量元素和對(duì)合金純度的要求，分別采用電弧爐、真空感應(yīng)爐以及電渣重熔等方法冶煉。為改善合金的加工性能，在冶煉過程中應(yīng)加強(qiáng)脫氧，防止鑄錠時(shí)二次氧化，減少偏析和粗大的柱狀結(jié)晶組織。 <br /> 可伐合金的生產(chǎn)過程注意事項(xiàng)：可伐合金的熱塑性加工應(yīng)避免在含硫氣氛中加熱雙錐回轉(zhuǎn)真空干燥機(jī)，以防止形成低熔點(diǎn)硫化鎳而造成工件的表面裂紋。可伐合金的冷塑性加工性能良好，每次退火軟化處理之后，冷加工變形率可達(dá)60～80%?？煞ズ辖鹪跓峒庸み^程中應(yīng)防止加熱溫度過高和加熱時(shí)間過長(zhǎng)，以避免晶粒粗化。<br /> 一般情況下，可伐合金的生產(chǎn)出現(xiàn)問題有外觀上的缺陷、氣孔和夾渣、裂紋、未焊透以及未熔合。其中可伐合金外觀缺陷是指不用借助于儀器,從工件表面可以發(fā)現(xiàn)的缺陷。常見的外觀缺陷有咬邊、焊瘤、凹陷及焊接變形等,有時(shí)還有表面氣孔和表面裂紋。單面焊的根部未焊透等。因此焊接可伐合金時(shí)一定要注意。氣孔和夾渣分別為氣孔：氣孔是指焊接可伐合金時(shí),熔池中的氣體未在金屬凝固前逸出,殘存于焊縫之中所形成的空穴。夾渣：夾渣是指焊后可伐合金溶渣殘存在焊縫中的現(xiàn)象。</div><p><img
