和玻璃封接用的鉻鐵合金是含鉻28%的鉻鐵合金，又稱做高鉻鋼或28號(hào)膨脹合金。合金中由于加入了鉻，使膨脹系數(shù)降低，因此可與軟玻璃進(jìn)行匹配封接。含鉻量高的鉻鐵合金，一般在室溫至熔點(diǎn)溫度的全部范圍內(nèi)將是鐵氧體的狀態(tài)，所以也稱做鐵氧體的鉻鐵合金。這種合金在封接前需在濕氫中加熱到950℃，使表面形成灰綠色的、薄而致密的CrO3及Fe2O3的氧化層，這種氧化層能很好地溶入玻璃并形成草綠色或褐綠色的封接面。這種合金的特點(diǎn)是，由于含鉻量大于28%，因而其相變點(diǎn)特別高。一般顯像管的第二陽極引線帽及彩色顯像管中屏上固定蔭罩框架的錐頭。圓掃描示波管的偏轉(zhuǎn)電極針等，以及盤形芯柱的管針，均是由高鉻鋼制的。過去當(dāng)顯像管玻璃錐體的壓制工藝未解決時(shí)，曾用高鉻鋼作成金屬錐體，再和玻璃屏進(jìn)行封接，這在一些老式顯像管中還可看到。然而必須注意，當(dāng)加熱到800-1200℃以上時(shí)，將產(chǎn)生奧斯丁體鐵，這種奧斯丁體的膨脹系數(shù)要比鐵氧體的鉻鐵合金大得多，并且在較低溫度時(shí)，仍能穩(wěn)定地保存在合金中，在這種情況下，將使膨脹系數(shù)改變，因而就會(huì)出現(xiàn)膨脹系數(shù)特性曲線不正常的危險(xiǎn)，而使材料不適合和玻璃封接。因此，鐵氧體的鉻鐵合金無論是在冶煉生產(chǎn)中或是在使用中，對(duì)于奧斯丁體的出現(xiàn)，必須給予很大的注意。<br /> 鉻鐵合金沒有氧化的危險(xiǎn)，所產(chǎn)生的綠到鼠灰色的氧化鉻及氧化鐵表面層，是非常牢固地附著在合金絲上，并且在封接過程中還可防止進(jìn)一步的氧化。 </p></div><p><img src="http://2024aiimg.qy55.com//cjjhb_soft/86/1136/202402212305177772.jpg"

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?？煞ズ辖鸬睦渌苄约庸ば阅芰己?，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，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

title="可伐合金毛細(xì)管_可定制"><br></p><div id="61zj9ic" class="khcont">可控氣氛<br /> 在可伐合金中總存在著各種雜質(zhì)，其中既有固態(tài)雜質(zhì)，如碳、錳、硅等等，也含有氣態(tài)雜質(zhì)，如H2O、CO和CO2。其中由于碳在高溫封接中，會(huì)與水氣或氧發(fā)生氧化反應(yīng)，產(chǎn)生CO2或CO，導(dǎo)致漏氣、漏孔，因此在退火過程中，對(duì)可伐零件表面進(jìn)行脫碳處理就顯得十分必要。另外，可伐零件的表面也或多或少地存在著金屬氧化物，故將金屬氧化物進(jìn)行還原也是必需的。眾所周知，氫氣是一種還原性氣體，它能還原金屬氧化物，同時(shí)當(dāng)溫度在700℃以上時(shí)，它具有一定的脫碳作用，而水蒸汽具有強(qiáng)烈的脫碳作用。因此，一般選擇濕氫作為可伐零件退火的氣氛。在高溫濕氫中，發(fā)生如下化學(xué)反應(yīng)：<br /> 上述化學(xué)反應(yīng)是可逆反應(yīng)，在密閉容器中反應(yīng)是不能進(jìn)行到底的，只能達(dá)到一個(gè)動(dòng)態(tài)的平衡。對(duì)式(2)和(3)來說，水蒸汽是氧化性氣體，而H2是還原性氣體，為了使退火中的[Fe]不被氧化，應(yīng)控制退火爐中的氣氛為還原氣氛。根據(jù)在上述反應(yīng)中，水蒸汽處于一種比較活躍的位置，所以只要控制了爐中水蒸汽含量，便可控制爐中的氣氛。在生產(chǎn)中通過測(cè)量“露點(diǎn)”來間接測(cè)量水蒸汽含量。在可控氣氛退火爐中，為防止空氣向爐內(nèi)擴(kuò)散，通常爐內(nèi)氣壓略大于101325 Pa，為方便計(jì)算，則假定爐內(nèi)氣壓為101325 Pa，采用1000℃的退火溫度。，Kp為當(dāng)反應(yīng)達(dá)到平衡時(shí)的平衡常數(shù)，A為固體反應(yīng)物的活度，P為氣體反應(yīng)物的分壓強(qiáng)。</div><p><img
