為了保護(hù)鉆具和套管在鉆井過程中不至于過度磨損，采用堆焊方式或(其他方法)將堆焊材料沿鉆桿接頭圓周方向堆焊(或熔敷)寬約30～50mm、厚2～3mm的環(huán)形帶。此環(huán)形帶即稱之為鉆桿接頭耐磨帶。目前在工程上使用的耐磨帶堆焊材料主要有鐵基合金粉末、碳化鎢顆粒和耐磨帶焊絲。 </p> <p> <br /> </p> <p> 一、鐵基合金粉末 </p> <p> <br /> </p> <p> 鐵基合金粉末是通過調(diào)整18-8型或Cr13型不銹鋼的Ni、Cr含量，并添加B、Si元素而成的。鐵基合金粉末的噴涂層硬度、致密性、結(jié)合強(qiáng)度等于鎳基合金粉末涂層大體相當(dāng)，因此在不少場(chǎng)合下可代替鎳基合金粉末，但涂層的韌性低于鎳基合金粉末涂層。鐵基合金粉末涂層具有良好的耐磨性。 </p> <p> <br /> </p> <p> 鉆桿接頭耐磨帶堆焊鐵基合金粉末采用的是等離子弧堆焊方法。等離子弧堆焊是利用轉(zhuǎn)移型等離子弧作為熱源，以鐵基合金粉末作填充金屬的一種堆焊工藝。其焊接溫度較高，容易造成局部組.織變大，且重復(fù)堆焊性變差，在應(yīng)用過程中，容易出現(xiàn)耐磨帶的開裂和剝落。 </p> <p> <br /> </p><div style="width:100%;text-align:

等離子堆焊技術(shù)特點(diǎn)：微束等離子熔覆機(jī)所采用的等離子束，是一種電離弧，比弧焊機(jī)熱量更集中，所以加熱速度更快，為了獲得更集中的離子束，一般采用高壓縮比孔徑，小電流，以便控制基體溫度不致太高，避免引起退火變形。當(dāng)然這與YAG激光器加熱速度無法比擬。由于等離子弧為連續(xù)工作，造成機(jī)體冷卻相對(duì)較慢，形成的過渡區(qū)域比激光熔覆要深一些，這對(duì)硬面材料熔覆來說，應(yīng)力會(huì)釋放的好一些。2.設(shè)備特點(diǎn)：微束等離子熔覆設(shè)備是在直流焊機(jī)的基礎(chǔ)上發(fā)展而來，其電源·噴鎗·送粉器·擺動(dòng)器等，技術(shù)門檻低，容易制造，可靠性好，維護(hù)使用簡(jiǎn)單，耗電少，使用成本低，通用性好，生產(chǎn)成本低，適應(yīng)性好，便于規(guī)?；a(chǎn)，效益明顯，對(duì)環(huán)境要求低，對(duì)材料適應(yīng)***。隨著電氣技術(shù)的進(jìn)步，我國的焊機(jī)技術(shù)水平已經(jīng)具備足夠的支持能力。另外設(shè)備體積小，重量小，焊鎗可以手持把握，這使它使用起來更靈活方便，輔助工裝的造價(jià)便宜。</p><div
