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(shí)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(shí)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(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。 </p></div><p><p><img

title="可伐合金毛細(xì)管現(xiàn)貨銷售"><br></p><div id="znnn5b5" class="khcont">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

Kovar合金又稱封接合金或定膨脹合金。在-70至500℃溫度范圍內(nèi)，具有比較恒定的較低或中等程度膨脹系數(shù)的合金。主要類型有鐵鎳、鐵鎳鈷、鐵鎳鉻系合金。還有無氧銅、鎢、鉬及其合金和復(fù)合材料。主要用于電子工業(yè)及電真空工業(yè)作封接材料。<br /> 可伐合金組織結(jié)構(gòu)<br /> 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(shí)，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(shí)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(huì)促進(jìn)γ→α相變。</div><p><img
