腔體分層擴(kuò)散焊是一種針對(duì)復(fù)雜內(nèi)部結(jié)構(gòu)（比如復(fù)雜內(nèi)腔結(jié)構(gòu)）部件化整為零完成機(jī)械加工后再化零為整擴(kuò)散連接成所需整體的制造工藝。其步驟是：首先，不銹鋼鉆孔篩網(wǎng)，建立目標(biāo)件的三維結(jié)構(gòu)圖形；然后，通過選取合適位置沿三維結(jié)構(gòu)圖形特定方向的逐層剖切，獲得多層易于加工的較薄厚度的二維層狀結(jié)構(gòu)零件圖；第三，不銹鋼鉆孔篩網(wǎng)，通過各種精密加工或切割，按圖制造加工出各層狀結(jié)構(gòu)零件；第四，將各層狀零件按順組合，不銹鋼鉆孔篩網(wǎng)，并利用擴(kuò)散焊接獲得目標(biāo)零件。腔體分層擴(kuò)散焊原則上可以制造任意復(fù)雜結(jié)構(gòu)部件，且制造具有內(nèi)部流道或者腔體等復(fù)雜內(nèi)部結(jié)構(gòu)的部件時(shí)具有無可替代的優(yōu)勢(shì)。

真空擴(kuò)散焊接可在真空或氫氣等保護(hù)氣氛環(huán)境下進(jìn)行焊接，工藝參數(shù)主要包括擴(kuò)散溫度、擴(kuò)散壓力、保溫時(shí)間、中間層的確定等。 </p> <p> 擴(kuò)散壓力是擴(kuò)散焊過程中一個(gè)基本工藝特征，為了使被焊材料的原子彼此擴(kuò)散交換，必須使被焊表面緊密接觸，因此就需要施加壓力，它還起到破壞表面氧化膜和改善界面狀態(tài)促進(jìn)擴(kuò)散的作用，同種材料焊接時(shí)，擴(kuò)散壓力能促進(jìn)晶界轉(zhuǎn)移。焊接時(shí)如果壓力小于比較好壓力值，在連接界面可能出現(xiàn)未焊合。擴(kuò)散壓力應(yīng)高于材料屈服強(qiáng)度。

待焊表面狀態(tài)對(duì)擴(kuò)散焊接過程和接頭質(zhì)量的影響很大，特別是固態(tài)擴(kuò)散焊，必須在裝焊前對(duì)焊件表面進(jìn)行認(rèn)真準(zhǔn)備。 </p> <p> 一， </p> <p> 表面機(jī)械加工， </p> <p> 待焊表面要求達(dá)到平整光滑，為了使焊接間隙**小，微觀接觸點(diǎn)盡可能多。一般要求表面粗糙度值應(yīng)達(dá)到 Ra＞2.5 μm。用精車、精刨（銑）、磨削、研磨、拋光等方法都可以加工 </p> <p> 出所需的表面平面度和粗糙度。若是采用加入軟中間層的擴(kuò)散焊或過渡液相的擴(kuò)散焊，則粗糙度值可適當(dāng)放寬。 </p> <p> 二， </p> <p> 表面凈化處理， </p> <p> 表面凈化處理目的是氧化膜、油和吸附物。去除表面氧化物多用化學(xué)腐蝕方法，腐蝕劑可參考金相腐蝕液的配方。腐蝕速度不能過大，以防止產(chǎn)生腐蝕坑。當(dāng)腐蝕至露出金屬光澤，就立即用水沖凈和烘干。除油可用乙醇、三氯乙烯、**、洗滌劑等，也可采用在真空中加熱的方法去除焊件表面的有機(jī)物、水、氣體吸附層等。 </p> <p> <br />
