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，重慶房車鉆桿堆焊設(shè)備廠家、碳化鈮等。從機(jī)理上講，截齒耐磨堆焊層的作用是： </p> <p> <br /> </p> <p> 1、彌補(bǔ)或改變因硬質(zhì)合金刀頭釬焊工藝在齒體圓周形成的性能劣化現(xiàn)象（指先熱處理后釬焊工藝生產(chǎn)的截齒）。 </p> <p> <br /> </p> <p> 2、進(jìn)一步優(yōu)化或強(qiáng)化刀頭部分使用性能。當(dāng)然，采用先釬焊刀頭后整體熱處理截齒的制造工藝時(shí)，后者的作用更為突出。然而，實(shí)際情況并不簡(jiǎn)單，截齒耐磨堆焊層的出現(xiàn)和使用，重慶房車鉆桿堆焊設(shè)備廠家，將截齒刀頭與被切割煤巖之間的磨擦、沖擊等作用，轉(zhuǎn)換為或部分轉(zhuǎn)換為堆焊層與被切割煤巖之間的磨擦、沖擊等作用。它們之間的磨擦磨損、沖擊損傷等，不僅取決于兩個(gè)接觸體材料的特性及其匹配行為，重慶房車鉆桿堆焊設(shè)備廠家，同時(shí)還受到采煤過程中諸多因素的影響。

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)移弧電源正極通過電纜接噴焊鎗噴嘴，轉(zhuǎn)移弧電源正極通過電纜接工件。冷卻水通過水冷電纜引至焊鎗，冷卻噴嘴和電極。氬氣通過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>
