加熱速度與冷卻速度也是熱處理工藝中兩個重要的參數(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、保溫時間和退火可控氣氛密切相關(guān)。只要上述三個條件掌握適當(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

Kovar®是一種真空熔煉的鐵鎳鈷低膨脹合金，化學(xué)成分含量被控制在非常窄的范圍內(nèi)，以保證的均衡熱膨脹性能。同時，制造過程中嚴格地質(zhì)量控制也確保了均衡的物理及機械性能，更加適合深沖壓，沖壓及各類切削加工。<br /> 材料用途<br /> Kovar®用于硬玻璃及陶瓷的真空密封。廣泛用于電子管，微波管，晶體管和二極管。在集成電路上，它被用于扁平集成電路和雙列直插式封裝。<br /> 密封準備<br /> 所有Kovar®制作的零件應(yīng)該在濕氫氣氛中進行脫氣和退火處理。氫在室溫下注入水中，通過水泡達到潮濕，必須小心防止表面碳化。熱處理爐要有提供同樣的氣氛的冷卻室。熱處理在1540/2010°F (838/1099°C)溫度范圍內(nèi)進行，熱處理時間為從溫度開始，20分鐘升到溫度，隨后零件移到冷卻區(qū)域，冷卻到570°F (299°C)后取出。<br /> 金屬與硬玻璃的密封時，金屬有一層氧化膜，的氧化膜是薄的并緊緊吸附于金屬表層。這樣的氧化膜可以通過將零件在大氣環(huán)境下加熱到1200/1290°F (650/700°C) ，并持續(xù)一段時間到深灰色表層變成淡褐色氧化膜。</div><p><img src="http://2024aiimg.qy55.com//cjjhb_soft/86/1136/202402212304564776.jpg" title="質(zhì)量可靠的可伐合金毛細管廠家"><br></p><p><img

這種合金屬于精密合金，也是鐵、鎳、鈷的合金，又稱為陶瓷可伐。在-60-600℃時它的膨脹系數(shù)與95%氧化鋁陶瓷相近，常用來和陶瓷作匹配封接。在金屬陶瓷發(fā)射管、行波管、速調(diào)管等器件和真空電容器中，鐵鎳鉆陶瓷封接合金廣泛地用來制作引出線、引出環(huán)、管殼等零件。<br /> 鐵鎳鈷玻璃封接合金<br /> 這種合金屬于精密合金，又稱可伐。它是鐵、鎳、鈷的合金，一般含鎳29%，鈷18%，其余是鐵。其膨脹系數(shù)由于鈷的加入而降低，與鉬及硬玻璃相近，適合于和硬玻璃作匹配封接。封接時表面生成有氧化鉆的氧化層，而氧化鈷極易溶于玻璃中而形成鼠灰色的封接面。<br /> 玻璃封接用鉻鐵合金<br /> 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，因此可與軟玻璃進行匹配封接。含鉻量高的鉻鐵合金，一般在室溫至熔點溫度的全部范圍內(nèi)將是鐵氧體的狀態(tài)，所以也稱做鐵氧體的鉻鐵合金。 </p></div><p><img

h的保溫時間內(nèi)能夠完全再結(jié)晶的溫度。金屬所受變形度越大，所具內(nèi)能越大，則其再結(jié)晶溫度就越底。工業(yè)上再結(jié)晶退火溫度一般要比再結(jié)晶溫度高100～200℃左右，保溫時間為30～60min?？煞サ脑俳Y(jié)晶溫度大約為700～750℃，因此其再結(jié)晶退火溫度應(yīng)為900～950℃。有資料介紹可伐的再結(jié)晶退火溫度為930℃左右，若單純只為了加工硬化和形變應(yīng)力，則以930℃保溫30～60min即可。但在金屬外殼封接工藝中，可伐與玻璃的實際燒結(jié)溫度高達到960℃，為了保證在這一溫度下，能得到更純、含雜質(zhì)更少的可伐材料，一般要求退火溫度不應(yīng)低于燒結(jié)溫度：退火溫度＝燒結(jié)溫度+30～50℃,達到1000±10℃，高于可伐的再結(jié)晶退火溫度。為了避免過高的溫度引起材料晶體顆粒的二次再結(jié)晶，使晶粒不均勻長大，可以通過縮短保溫時間來控制?？傊嘶饻囟仍礁?，保溫時間就相應(yīng)縮短。<br /> 當(dāng)裝爐量大或零件尺寸較大時，應(yīng)適當(dāng)延遲保溫時間，此時退火溫度不應(yīng)太高，防止熱透不均勻，局部晶粒長大。</div><p><img src="http://2024aiimg.qy55.com//cjjhb_soft/86/1136/202402212304307062.jpg"
