(1)鎳-鉻系合金熱噴涂粉末：該種類較多，例如鎳-鉻耐熱合金，是在鎳中加入20%鉻制成的。鎳-鉻耐熱合金在高溫下幾乎不氧化，是典型的耐熱、耐蝕和耐高溫氧化的涂層材料。涂層致密，與基體金屬的粘結(jié)性能良好，是陶瓷、軟金屬等材料的涂層與基體的的過渡層材料，既能增加基體防高溫氣體侵蝕的能力，又能改善涂層與基體材料的粘結(jié)強(qiáng)度。 </p> <p> (2)鎳-鉻-鐵系合金熱噴涂粉末：此類熱噴涂粉末是在鎳-鉻中加入適當(dāng)?shù)蔫F，其耐高溫氧化性能比鎳-鉻系合金稍差一些，其他性能基本上與鎳-鉻系合金接近，突出的優(yōu)點(diǎn)是價(jià)格比較便宜，因此可用作耐蝕工件的修補(bǔ)，也可做過渡層熱噴涂粉末用。 </p> <p> (3)鎳-鉻-硼系合金熱噴涂粉末：此系合金由于含有硼、鉻和碳等元素，硬度比較高，韌性也適中，用噴涂后，其涂層耐磨、耐蝕、耐熱性較好，可用于軸類、活塞等的防腐修復(fù)。 </p> <p> (4)鎳-鋁合金熱噴涂粉末：常用來打底層，每個(gè)微粒都是由微細(xì)的鎳粉和鋁粉組成。當(dāng)噴涂時(shí)，熱噴涂粉末通過火焰被加熱到600攝氏度以上，鎳和鋁之間產(chǎn)生強(qiáng)烈的化學(xué)反應(yīng)，生成金屬間化合物，并放出大量的熱，同時(shí)，部分鋁還會(huì)氧化，產(chǎn)生更多的熱量。在此高溫下，鎳可擴(kuò)散到基材金屬中去，可以使涂層的結(jié)合強(qiáng)度明顯提高。 </p><p> 鎳基合金的起源和發(fā)展： </p> <p> <br /> </p> <p> 鎳基合金是30年代后期開始研制的，英國(guó)于1941年首先生產(chǎn)出鎳基合金 Nimonic75(Ni-20Cr-0.4Ti)；為了提高潛變強(qiáng)度又添加Al，研制出Nimonic 80(Ni-20Cr- 2.5Ti-1.3Al)；而美國(guó)于40年代中期，俄羅斯于40年代后期，中國(guó)于50年代中期也先后開發(fā)出鎳基合金。鎳基合金的發(fā)展包括兩個(gè)方面，即合金成分的改良和生產(chǎn)技術(shù)的革新。如50年代初，真空熔煉技術(shù)的發(fā)展，為煉制含高Al和Ti 的鎳基合金創(chuàng)造了條件，而帶動(dòng)了合金強(qiáng)度與使用溫度的大幅提高。50年代后期，由于渦輪葉片工作溫度的提高，要求合金有更高的高溫強(qiáng)度，但是合金的強(qiáng)度高了，就難以變形，甚至不能變形，于是采用精密鑄造技術(shù)，發(fā)展出一系列具有良好高溫強(qiáng)度的鑄造合金。 </p> <p> <br />

以鎳為基加入其他元素組成的合金。鎳具有良好的力學(xué)、物理和化學(xué)性能，添加適宜的元素可提高它的抗氧化性、耐蝕性、高溫強(qiáng)度和改善某些物理性能。鎳基高溫合金在650～1000℃高溫下有較高的強(qiáng)度和抗氧化、抗燃?xì)飧g能力，是高溫合金中應(yīng)用**廣、高溫強(qiáng)度比較高的一類合金。 </p> <p> 應(yīng)用方向： </p> <p> 鎳合金主要用于熱處理工業(yè)的爐輥、鐘式爐及退火爐，化工和石油化工的蒸汽裂化粗汽油爐，核工業(yè)的核廢料清洗設(shè)備，冶金工業(yè)的鐵礦石、海綿鈦還原工藝等。同時(shí)也用于自動(dòng)化裝置如催化支撐系統(tǒng)、火花塞，閥門密封件，以及噴涂材料等。鎳基合金粉末可用于3D打印激光/電子束增材制造（SLM/EBM）、激光直接沉積（DLD）、粉末熱等靜壓成型（HIP）、金屬注塑模成型（MIM）、冷/熱噴涂涂層等工藝。

style="text-indent:25px">應(yīng)力和應(yīng)變率的關(guān)系隨潛變機(jī)制的不同而有所不同，一般說來，溫度的升高或是應(yīng)力的增加都會(huì)增加穩(wěn)態(tài)潛變的變形速率并縮短潛變壽命。潛變之機(jī)制可分為(1)差排潛變：受到高溫的幫助，差排可能沿滑移面發(fā)生滑移，進(jìn)而發(fā)生變形。(2)擴(kuò)散潛變：由原子移動(dòng)造成，沿晶粒散的稱為Nabarro-Herring Creep，在高溫時(shí)為主要機(jī)制。沿晶界擴(kuò)散的叫做Coble Creep，在低溫時(shí) 為主要機(jī)制。因此晶粒越小越容易發(fā)生擴(kuò)散潛變。(3)晶界滑移：因高溫時(shí)晶界較弱，材料易沿晶界產(chǎn)生滑移，造成沿晶裂縫。陜西專業(yè)激光熔覆粉末服務(wù)電話</p><p
