等離子粉末堆焊，一般而言,堆焊的金屬首先應(yīng)滿足焊件的使用條件;其次考慮堆焊的金屬焊接性要好,再后適當(dāng)選擇比較經(jīng)濟(jì)的堆焊金屬。常見的工作環(huán)境條件下使用的堆焊金屬有:高應(yīng)力金屬間磨損選用亞共晶鈷基合金、含金屬間化合物的鈷基合金；低應(yīng)力金屬間磨損選用堆焊用低合金鋼；金屬間磨損＋腐蝕或氧化選用大多鈷基合金或鎳基合金；低應(yīng)力磨料磨損、沖擊浸蝕、磨料浸蝕選用高合金鑄鐵；低應(yīng)力嚴(yán)重磨料磨損、切割刃選用碳化物；氣蝕浸蝕選用鈷基合金；嚴(yán)重沖擊選用高合金錳鋼；嚴(yán)重沖擊＋腐蝕＋氧化選用亞共晶鈷基合金；高溫下金屬間磨損選用亞共晶鈷基合金、含金屬間化合物的鈷基合金；鑿削式磨料磨損選用奧氏體錳鋼；熱穩(wěn)定性高溫蠕變強(qiáng)度(540℃)選用鈷基合金碳化物型鈷基合金。</p><p> 為了解決截齒在采煤過程中的快速磨損失效問題，采用堆焊方式（或其他冶金方式）在截齒錐頂（硬質(zhì)合金刀頭）以下齒體部位，沿圓周方向堆焊一個(gè)寬度約20-30mm、厚度2-3mm的環(huán)形帶。此環(huán)形帶即稱之為耐磨堆焊層。常用的耐磨堆焊材料為馬氏體堆焊合金（Ｄ３１７，Ｄ３２７，ＤＧ７等）、高鉻Fe-Cr-C合金系（Ｄ６８８，Ｄ６３８等）、碳化鎢、碳化鈮等。從機(jī)理上講，截齒耐磨堆焊層的作用是：

等離子粉末堆焊是一種先進(jìn)的堆焊工藝，它是選用氬氣等離子電弧作熱源，選用粉末狀合金作填充料的主動(dòng)堆焊辦法。比較于傳統(tǒng)的電焊、氬弧焊等堆焊辦法，等離子粉末堆焊存在著堆焊成型好、熔深可控、結(jié)合度高、致密度好、易于完畢主動(dòng)化等特征，因此也是閥門企業(yè)央求特種設(shè)備制作許可證（TS）A級認(rèn)證時(shí)，相關(guān)認(rèn)證部分要求必備的設(shè)備。

1、等離子弧區(qū)溫度高，所以能熔的材料特別***，可以對各種金屬進(jìn)行堆焊，還能選配各種不同性能的粉末進(jìn)行配置使用；而且等離子堆焊穩(wěn)定性好，粉末能均勻地噴射進(jìn)入弧柱以熔化材料，所以，堆焊層有很好的機(jī)械性能，和很高的粉末材料密度。 </p> <p> 2、離子堆焊沉積效率比較高，它可以自動(dòng)化操作，能很好的調(diào)節(jié)；為了保證合金材料性能，它有小于5%稀釋率，使用保護(hù)氣，不易氧化堆焊材料，在工作時(shí)一般采用氬氣和氦氣操作。 </p> <p> 3、離子堆焊有光滑平整的的堆焊層，而且可以精確控制尺寸范圍。堆焊件不容易變形，因?yàn)槎押笗r(shí)的粉末在弧柱中熔化并起到隔離作用，冷卻工件還可以使用氣體。 </p> <p> 4、等離子堆焊的技術(shù)優(yōu)勢更加明顯，母材和堆焊層實(shí)現(xiàn)了冶金結(jié)合，而且堆焊層不容易脫落，在堆焊的時(shí)候可以根據(jù)性能選擇堆焊合金材料，終達(dá)到耐磨和抗腐蝕，耐高溫和抗氧化等目的。 </p> <p> <br /> </p> <p> 重慶噴焊鉆桿堆焊等離子堆焊機(jī)</p><p
