玻璃封裝后并鍍金的可伐合金零件可伐合金，英文：KOVAR["k?:vɑ:]；譯文：可伐、科瓦、柯伐（也稱鐵鎳鈷合金，相當(dāng)于GB 4J29，ASTM F15，UNS K94610）；KOVAR為含鎳29%，鈷17%的硬玻璃鐵基封接合金。<br /> 該合金在20~450℃范圍內(nèi)具有與硬玻璃相近的線膨脹系數(shù)和相應(yīng)的硬玻璃能進(jìn)行有效封接匹配，和較高的居里點(diǎn)以及良好的低溫組織穩(wěn)定性，合金的氧化膜致密，容易焊接和熔接，有良好可塑性，可切削加工，廣泛用于制作電真空元件，發(fā)射管，顯像管，開(kāi)關(guān)管，晶體管以及密封插頭和繼電器外殼等?？煞ズ辖鹨?yàn)楹挸煞?，產(chǎn)品比較耐磨。可伐易與鉬組玻璃進(jìn)行配合封接，一般工件表面要求鍍金。其狀態(tài)有硬態(tài)和軟態(tài)兩種。 <br /> 可伐合金的物理性能：密度：8.17 克/立方厘米電阻率：0.46 Ω*平方厘米/米導(dǎo)電率：2.174 * 1000000 S/m 熱導(dǎo)率：0.046卡/cm*s*℃</div><p><img src="http://2024aiimg.qy55.com//cjjhb_soft/86/1136/202402212305248263.jpg"

class="khcont">可伐合金毛細(xì)管退火溫度及保溫時(shí)間<br /> 可伐合金是一種奧氏體組織材料，所以，只能通過(guò)晶體的重新形核和長(zhǎng)大，即再結(jié)晶退火來(lái)加工硬化和形變應(yīng)力。<br /> 再結(jié)晶溫度是指經(jīng)過(guò)大變形量冷加工的金屬，在1 h的保溫時(shí)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(shí)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(shí)際燒結(jié)溫度高達(dá)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(dá)到1000±10℃，高于可伐的再結(jié)晶退火溫度。為了避免過(guò)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(zhǎng)大，可以通過(guò)縮短保溫時(shí)間來(lái)控制。總之，退火溫度越高，保溫時(shí)間就相應(yīng)縮短。<br /> 當(dāng)裝爐量大或零件尺寸較大時(shí)，應(yīng)適當(dāng)延遲保溫時(shí)間，此時(shí)退火溫度不應(yīng)太高，防止熱透不均勻，局部晶粒長(zhǎng)大。</div><p><img src="http://2024aiimg.qy55.com//cjjhb_soft/86/1136/202402212305148283.jpg"
