</p> <p> <p> 鎳合金具有優(yōu)良的耐高溫、耐腐蝕及耐磨損等性能，其熔焊時(shí)焊接性差，接頭韌性遠(yuǎn)低于母材，因此較多地應(yīng)用擴(kuò)散焊實(shí)現(xiàn)連接。 </p> <p>

按被焊材料的組合形式來分可分為無中間層擴(kuò)散焊和加中間層擴(kuò)散焊，按照焊接母材不同，也可分為同種材料擴(kuò)散焊和異種材料焊接。 </p> <p> 異種材料焊接在接頭處會(huì)形成不同于機(jī)體的新相，新相的性能決定焊接接頭的性能，因此研究元素在接頭中的擴(kuò)散規(guī)律并預(yù)測(cè)新相的生成極其重要。 </p> 一種利用材料的高延展性來加速界面接觸過程，形成了超塑性成形擴(kuò)散焊。由于超塑性材料所具備的超細(xì)晶粒，增加了界面區(qū)的晶界密度和晶界擴(kuò)散的作用，增加了孔洞和界面消失的過程[1]。超塑性擴(kuò)散焊可以是兩邊母材具有超塑性，也可以是添加超塑性中間層材料實(shí)現(xiàn)擴(kuò)散連接。<p> 焊接時(shí)間， </p> <p> 擴(kuò)散焊接時(shí)間又稱保溫時(shí)間，是指被焊件在焊接溫度下保持的時(shí)間。擴(kuò)散焊所需的保溫時(shí)間與溫度、壓力、中間擴(kuò)散層厚度、接頭成分及均勻化的要求密切相關(guān)，也受材料表面狀態(tài)和中間層材料的影響。 </p> <p> <br /> </p> <p> 環(huán)境氣氛， </p> <p> 擴(kuò)散焊一般在真空或保護(hù)氣氛環(huán)境下進(jìn)行。真空度、保護(hù)氣體純度、流量和壓力等均會(huì)影響擴(kuò)散焊接頭質(zhì)量。真空度越高，凈化作用越強(qiáng)，焊接效果越好。但真空度過高會(huì)增加生產(chǎn)成本，常用的真空度為（1~20）X 10-3 Pa。 </p> <p> 擴(kuò)散焊中常用的保護(hù)氣體是Ar氣。對(duì)于有些材料也可以采用高純度N2、H2或He氣。純H2氣氛能降低氧化物形成趨勢(shì)，并能在高溫下使許多金屬的表面氧化物層減薄。但使用這些氣體時(shí)純度必須很高以防止造成重新污染。H能與Zr、Ti、Nb（鈮）和Ta（鉭）形成不利的氫化物，應(yīng)注意避免。 </p> <p> <br /> </p> <p> 表面狀態(tài) </p> <p> <br /> </p> <p> 焊件表面的平面度和粗糙度是影響擴(kuò)散焊接頭質(zhì)量的重要因素。擴(kuò)散焊時(shí)焊件表面應(yīng)光滑平整，一般焊前先進(jìn)行機(jī)械加工，然后去除加工表面的油、銹及表面氧化物。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p>

擴(kuò)散焊（DFW）是將緊密接觸的焊件置于真空或保護(hù)氣氛中，并在一定溫度和壓力下保持一段時(shí)間，使接觸界面之間的原子相互擴(kuò)散而實(shí)現(xiàn)可靠連接的一種固相焊接方法。 </p> <p>
