等離子堆焊做為一種新技術(shù)焊接工藝得到了越來越多的重視和利用。一種氣體經(jīng)過電離作用后產(chǎn)生陽離子和陰離子，兩種離子處在同一個共同體內(nèi)，這種處于電離情況的氣體就稱為等離子體，等離子焊劑就是電弧等離子體作為作業(yè)動力的焊接方法。等離子堆焊一般分為堆焊、噴焊、噴涂等工藝類型。等離子堆焊運用釷鎢棒做電極，運用的保護(hù)氣體有氦、氬、氫、氮等，其間氮氣比較常用，等離子堆焊也是氣體保護(hù)焊的一種。 </p> <p> 等離子粉末堆焊是以等離子弧作為熱源，應(yīng)用等離子弧產(chǎn)生的高溫將合金粉末與基體表面迅速加熱并一起熔化、混合、擴(kuò)散、凝固，等離子束離開后自激冷卻，形成一層高性能的合金層，從而實現(xiàn)零件表面的強(qiáng)化與硬化的堆焊工藝。 </p> <p> <br /> </p><p style="text-indent:25px"> 石油鉆桿接頭是在石油勘探開采鉆井時，用于連接上、下鉆桿的重要部件，由于其長期工作在含砂多，且有一定腐蝕性介質(zhì)的井下，所以要求其具有優(yōu)良的耐磨、耐蝕性能。為了改善其耐磨、耐蝕性能，提高其使用壽命，目前國內(nèi)許多企業(yè)采用粉末等離子噴焊的方法在其接頭部位噴焊一層耐磨帶。實驗結(jié)果表明，噴焊層主要由：γ-Fe、Cr23C6、(Cr,Fe)7C3以及NiB、萊氏體等化合物相組成。焊層冶金結(jié)合較好，**致密，稀釋率低，無裂紋、夾雜等缺點。同時擁有較高的硬度（55～68HRC）和耐磨性，具有較大的應(yīng)用價值。2、鉆桿是石油天然氣行業(yè)進(jìn)行油氣資源勘探，開發(fā)過程中不可或缺的工具，是組成鉆柱的主要部件。在石油勘探開采鉆井時，鉆桿接頭用于連接上、下鉆桿，是石油鉆桿的薄弱環(huán)節(jié)，80%以上的鉆桿***出現(xiàn)在這個部位。因此提高鉆桿接頭的質(zhì)量，是降低***的關(guān)鍵。3、據(jù)了解，目前國內(nèi)大部分油田的鉆井深度都達(dá)到了幾百米，有的甚至更深，達(dá)到幾千米，而且?guī)r層復(fù)雜堅硬，鉆桿在工作過程中，其外壁尤其是接頭部位要與井壁或套管接觸，所以承受著劇烈的磨損。由于鉆桿接頭周圍接觸面存在很多硬質(zhì)點，所以磨損主要以磨粒磨損為主，特別是下部目的層段使用屏蔽暫堵鉆井液時。鉆桿堆焊設(shè)備的研發(fā)途徑。</p><div

style="text-indent:25px">在堆焊過程中，焊炬除了按上述方法作階梯式的向前移動外，還需沿著堆焊面作橫向擺動，這樣可以提高堆焊層的均勻性和平整度。每堆焊一層可得到2～3mm厚的堆焊層，每層連續(xù)一次堆焊好。如果需要得到更厚的堆焊層，則須多層堆焊，層間須用砂輪或鋼絲刷進(jìn)行清理和平整，而后再堆焊下一層。根據(jù)需要可以用火焰重新熔化堆焊層（重熔），以減少堆焊層金屬的缺點，提高堆焊層質(zhì)量。（3）堆焊時，焊絲的熔化端、熔池必須始終處于“三倍乙炔過剩焰”的保護(hù)之中，使它們與空氣隔絕。不得將焊炬急速地從熔池表面移開。堆焊搭接時，應(yīng)使接頭重疊15～20mm，收尾時須將焊炬繼續(xù)前移40～50mm，焊炬逐漸抬起，火焰逐漸離開熔池，使熔池逐漸縮小。這樣，接頭處的冷卻速度緩慢，不至于產(chǎn)生接頭疏松、縮孔、火口裂紋等缺點?；鹧媸湛谠诃h(huán)縫的內(nèi)側(cè)為好，這樣可以減少堆焊接頭的收縮應(yīng)力。等離子粉末堆焊是以等離子弧作為熱源，應(yīng)用等離子弧產(chǎn)生的高溫將合金粉末與基體表面迅速加熱并一起熔化、混合、擴(kuò)散、凝固，等離子束離開后自激冷卻，形成一層高性能的合金層，從而實現(xiàn)零件表面的強(qiáng)化與硬化的堆焊工藝。重慶等離子鉆桿堆焊堆焊房車</p><p
