content="在堆焊過(guò)程中，焊炬除了按上述方法作階梯式的向前移動(dòng)外，還需沿著堆焊面作橫向擺動(dòng)，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"><meta name="keywords"

盡管目前仍存在著許多問(wèn)題，由于其優(yōu)異的技術(shù)特性，等離子堆焊技術(shù)在國(guó)內(nèi)外仍得到了大量應(yīng)用。在實(shí)際的工業(yè)生產(chǎn)中，等離子堆焊主要用于表面技術(shù)，以提高工件(閥門(mén)密封面、氣閥密封面、模具刃口、輸煤機(jī)中部槽板、槽幫、無(wú)縫鋼管頂頭、運(yùn)動(dòng)部件摩擦副等)的耐磨性能，以及石化工業(yè)設(shè)備的耐腐蝕性能，同時(shí)延長(zhǎng)使用壽命為主要目標(biāo)。采用各種堆焊材料提高零部件的性能，也是生產(chǎn)和研究的重點(diǎn)。但這些研究工作***于材料的表面改性上。如今高溫合金已應(yīng)用于航空航天、工業(yè)燃汽輪機(jī)及高速機(jī)車(chē)等方面，在長(zhǎng)期使用中就要求具有高的強(qiáng)度、較佳的抗氧化性能、耐蝕性能和良好的低周疲勞抗力，通常合金的成分及**對(duì)其性能有重大的影響，因此通過(guò)等離子堆焊技術(shù)在高溫合金的成形及加工方面的應(yīng)用，獲得均勻細(xì)小的**結(jié)構(gòu)成為改進(jìn)合金綜合性能的重要手段。隨著制造業(yè)的快速發(fā)展，為了滿足各種行業(yè)的需要，尤其是在快速制造領(lǐng)域，等離子沉積制造技術(shù)也得到人們的注意。德陽(yáng)等離子設(shè)備上海等離子的發(fā)展方向是什么？</p><div

等離子粉末噴焊（PlasmaTransferredArc簡(jiǎn)稱PTA）是一種先進(jìn)的堆焊工藝。它是采用氬氣等離子電弧作熱源（轉(zhuǎn)移型等離子弧為主，非轉(zhuǎn)移型等離子弧為輔），采用粉末狀合金作填充料的自動(dòng)堆焊方法。在采用聯(lián)合型等離子弧噴焊時(shí)，一般采用兩**立的直流弧焊機(jī)作電源，分別供給非轉(zhuǎn)移弧和轉(zhuǎn)移弧。兩個(gè)電源的負(fù)極并聯(lián)在一起，通過(guò)電纜接至噴焊鎗的鎢電極（負(fù)極）。非轉(zhuǎn)移弧電源正極通過(guò)電纜接噴焊鎗噴嘴，轉(zhuǎn)移弧電源正極通過(guò)電纜接工件。冷卻水通過(guò)水冷電纜引至焊鎗，冷卻噴嘴和電極。氬氣通過(guò)電磁氣閥和浮子流量計(jì)進(jìn)入噴焊鎗。電源接通后，借助高頻火花引燃非轉(zhuǎn)移弧。再借助非轉(zhuǎn)移弧弧焰在鎢電極和工件之間造成的導(dǎo)電通道，引燃轉(zhuǎn)移弧。轉(zhuǎn)移弧引燃后，可保留或切斷非轉(zhuǎn)移弧。主要利用轉(zhuǎn)移弧在工件表面產(chǎn)生熔池。合金粉末由送粉器按需要量連續(xù)供給，借助送粉氣流（也用氬氣）送入焊鎗，并吹入電弧中。合金粉末在弧柱中被預(yù)先加熱，呈熔化或半熔化狀態(tài)，噴射到工件熔池里，在熔池里充分熔化，并排出氣體和浮出熔渣。通過(guò)調(diào)節(jié)轉(zhuǎn)移弧和非轉(zhuǎn)移弧電流，送粉量和其它工藝規(guī)范參數(shù)，來(lái)控制熔化合金粉末和傳遞給工件的熱量。隨著焊鎗和工件的相對(duì)移動(dòng)，合金熔池逐凝固。</p><p
