因焊接時所加壓力較小，工件多是整體加熱，隨爐冷卻，上海擠塑機(jī)過濾網(wǎng)片，故焊件整體塑性變形很小，焊后的工件一般不再進(jìn)行機(jī)械加工。 </p> <p> 因焊接所需壓力不大，上海擠塑機(jī)過濾網(wǎng)片，故大斷面焊接所需設(shè)備的噸位不高，易于實(shí)現(xiàn)。 </p> <p>

真空擴(kuò)散焊接技術(shù)是為了適應(yīng)原子能，航空，航天及電子工業(yè)等前列科學(xué)技術(shù)領(lǐng)域的需要而迅速發(fā)展起來的一種特種焊接工藝方法。它是在一定的真空度條件下，將兩個平整光潔的焊接表面加熱到一定的溫度，在不加任何焊料或中間金屬的情況下，在溫度和壓力的同時作用下，發(fā)生微觀塑性流變后相互緊密接觸，利用焊件接觸表面的電子，原子或分子互相擴(kuò)散轉(zhuǎn)移，并且形成離子鍵，金屬鍵或者共價鍵，經(jīng)一段時間保溫，使焊接區(qū)的成分，均勻化，達(dá)到完全的冶金連接過程。由此可見，擴(kuò)散焊接主要是依靠焊接表面發(fā)生微觀塑性流變后，達(dá)到緊密接觸，使原子相互大量擴(kuò)散而實(shí)現(xiàn)焊接的。它能夠完成用其他焊接方法難以實(shí)現(xiàn)的焊接工作，并且還可以實(shí)現(xiàn)互不溶解，高熔點(diǎn)金屬以及非金屬等異種材料之間的焊接。 </p><p> 真空擴(kuò)散焊是將兩個待焊工件緊壓在一起，并置于真空或保護(hù)氣氛爐內(nèi)加熱，使兩焊接表面微小的不平處產(chǎn)生微觀塑性變形，達(dá)到緊密接觸，在隨后的加熱保溫中，原子間相互擴(kuò)散而成冶金連接的焊接方法，通常這類擴(kuò)散焊稱之為固相擴(kuò)散。它的特點(diǎn)是待焊表面質(zhì)量要求高，焊接時間較長，接頭質(zhì)量不穩(wěn)定。 </p> <p> 隨著擴(kuò)散焊工藝的發(fā)展，出現(xiàn)了瞬間液相擴(kuò)散焊，它可降低待焊表面制備的質(zhì)量要求，減少焊接時間，提高接頭質(zhì)量的穩(wěn)定性。它常在待焊的表面間加一層有利于擴(kuò)散的中間材料，該材料在加熱保溫中熔化，并形成少量的液相，這些液相金屬可填充縫隙，也使液相中的某些元素向母材擴(kuò)散，形成冶金連接。鋁合金與氧化鋁陶瓷擴(kuò)散焊。</p><div

高溫合金中含有Cr、Al等元素，表面氧化膜很穩(wěn)定，難以去除，焊前必須嚴(yán)格加工和清理，甚至要求表面鍍層后才能進(jìn)行固相擴(kuò)散焊。 </p> <p> <p> 異種金屬材料的擴(kuò)散焊接，鋼與鋁、鈦、銅、鉬的擴(kuò)散焊。 <p> 鋼與鋁及鋁合金進(jìn)行擴(kuò)散焊的主要問題是焊接界面附近易形成Fe-Al金屬間化合物，使接頭強(qiáng)度下降。 </p> <p> 可采用增加中間過渡層的方法獲得牢固的接頭。 </p> <p> 一般可選用Cu和Ni。 </p> <p> 合金元素Mg、Si及Cu對鋼與鋁擴(kuò)散焊接頭的強(qiáng)度影響很大。 </p> <p> <br /> </p> </p> <p> <br /> </p> <p> <br /> </p> </p> <p> <br /> </p>
