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)中通過測量“露點(diǎn)”來間接測量水蒸汽含量。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

class="khcont">可伐合金毛細(xì)管加熱速度與冷卻速度<br /> 加熱速度與冷卻速度也是熱處理工藝中兩個(gè)重要的參數(shù)，但由于可伐合金的材料組織為奧氏體，其β一a的相變溫度為一78．5℃，因此一般情況下在加熱和冷卻過程中不存在相變問題。在裝爐量不大和零件腔壁較薄的情況下，加熱與冷卻速度的大小對退火效果的影響不大；但當(dāng)裝爐量較大或零件較厚的時(shí)候，由于爐中溫度一般是靠外部熱源的輻射和對流來的，爐內(nèi)溫度的變化體現(xiàn)在離熱源較近的零件上和零件的表面上，因此加熱速度太快，將使零件表面與心部產(chǎn)生溫度差，加熱速度越快，則內(nèi)外溫度差越大，熱應(yīng)力就越大，可能導(dǎo)致零件的變形和局部晶粒粗大，甚至開裂，這對金屬的封接是非常不利的。在這種情況下，必須要求控制加熱速度，具體處理需考慮裝爐量及零件厚薄，建議加熱速度每小時(shí)不超過300～600℃。當(dāng)然，冷卻也存在同樣的情況，亦給予同樣的考慮及處理。<br /> 可伐管殼類零件的退火處理是提高其封接質(zhì)量的重要前提，它的好壞直接影響金屬外殼的封裝質(zhì)量，而退火處理的質(zhì)量又與退火溫度、保溫時(shí)間和退火可控氣氛密切相關(guān)。只要上述三個(gè)條件掌握適當(dāng)，相互匹配并能根據(jù)具體情況靈活處理，就一定能保證可伐零件的退火質(zhì)量。</div><p><img
