</p> <p> 正確選擇擴(kuò)散焊參數(shù)是獲得質(zhì)量接頭的重要保證。 </p> <p> 材料的同素異構(gòu)轉(zhuǎn)變和顯微，它們對(duì)擴(kuò)散速率有很大的影響。 </p> <p> 母材能產(chǎn)生超塑性時(shí)，擴(kuò)散焊就容易進(jìn)行。 </p> <p> 增加擴(kuò)散速率的另一個(gè)途徑是合金化，確切地說是在中間層合金系中加入高擴(kuò)散系數(shù)的元素。 </p> <p> <br /> </p> <p> 根據(jù)工作空間所能達(dá)到的真空度或極限真空度，可以把擴(kuò)散焊設(shè)備分為四類，即低真空（0，不銹鋼絲網(wǎng)生產(chǎn)，不銹鋼絲網(wǎng)生產(chǎn).1Pa以上）、中真空（0. l Pa～10-3 Pa）、高真空（＜10-5Pa）焊機(jī)和低壓，不銹鋼絲網(wǎng)生產(chǎn)、高壓保護(hù)氣體擴(kuò)散焊機(jī)。 </p> <p> 根據(jù)焊件在真空中所處的情況，可分為焊件全部處在真空中的焊機(jī)和局部真空焊機(jī)。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br

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 />
