粉末冶金產(chǎn)業(yè)和技術(shù)的高速發(fā)展2019-09-26我國(guó)粉末冶金行業(yè)已經(jīng)經(jīng)過了近10年的高速發(fā)展，但與國(guó)外的同行業(yè)仍存在以下幾方面的差距：(1)企業(yè)多，規(guī)模小，經(jīng)濟(jì)效益與國(guó)外企業(yè)相差很大。(2)產(chǎn)品交叉，企業(yè)相互壓價(jià)，競(jìng)爭(zhēng)異常激烈，普陀區(qū)質(zhì)量金屬注射成型質(zhì)量保證。(3)多數(shù)企業(yè)缺乏技術(shù)支持，研發(fā)能力落后，產(chǎn)品檔次低，難以與國(guó)外競(jìng)爭(zhēng)。(4)再投入缺乏與困擾。(5)工藝裝備、配套設(shè)施落后。(6)產(chǎn)品出口少，貿(mào)易渠道不暢。隨著我國(guó)加入WTO以后，以上種種不足和弱點(diǎn)將改善，這是因?yàn)榧尤隬TO后，市場(chǎng)逐漸國(guó)際化，粉末冶金市場(chǎng)將得到進(jìn)一步擴(kuò)大的機(jī)會(huì)；而同時(shí)隨著國(guó)外資金和技術(shù)的進(jìn)入，粉末冶金及相關(guān)的技術(shù)水平也必將得到提高和發(fā)展。據(jù)《2013-2017年中國(guó)粉末冶金制造行業(yè)產(chǎn)銷需求預(yù)測(cè)與轉(zhuǎn)型升級(jí)分析報(bào)告》數(shù)據(jù)顯示，目前，中國(guó)粉末冶金零件及含油軸承總產(chǎn)值超過55億元，占全球市場(chǎng)比重較小，發(fā)展空間也較為廣闊。根據(jù)中國(guó)機(jī)協(xié)粉末冶金專業(yè)協(xié)會(huì)對(duì)53家企業(yè)統(tǒng)計(jì)數(shù)據(jù)顯示，2010年中國(guó)粉末冶金零件行業(yè)實(shí)現(xiàn)主營(yíng)業(yè)務(wù)收入，同比增長(zhǎng)，普陀區(qū)質(zhì)量金屬注射成型質(zhì)量保證，較上年增加了一倍。在產(chǎn)值方面，粉末冶金零件行業(yè)實(shí)現(xiàn)工業(yè)總產(chǎn)值，其中新產(chǎn)品產(chǎn)值，普陀區(qū)質(zhì)量金屬注射成型質(zhì)量保證，新產(chǎn)品率(新產(chǎn)品產(chǎn)值/工業(yè)總產(chǎn)值)為，其中出**貨值，出口率(出**貨值/工業(yè)銷售產(chǎn)值)為。因此不管是粉末還是粘結(jié)劑都應(yīng)該符合要求，否則將影響粉末冶金制品的成形。普陀區(qū)質(zhì)量金屬注射成型質(zhì)量保證</p><div

粉末冶金材料的熱處理工藝2019-09-25粉末冶金材料的熱處理工藝粉末冶金材料的熱處理工藝您了解嗎?如今粉末冶金材料被應(yīng)用得越來越，它們?cè)谌〈兔芏?、低硬度和?qiáng)度的鑄鐵材料方面已經(jīng)具有明顯優(yōu)勢(shì)。粉末冶金材料的熱處理有淬火、化學(xué)熱處理、蒸汽處理和特殊熱處理幾種形式：1、淬火熱處理工藝粉末冶金材料由于孔隙的存在，在傳熱速度方面要低于致密材料，因此在淬火時(shí)，淬透性相對(duì)較差。另外淬火時(shí)，粉末材料的燒結(jié)密度和材料的導(dǎo)熱性是成正比關(guān)系的;粉末冶金材料因?yàn)闊Y(jié)工藝與致密材料的差異，內(nèi)部均勻性要優(yōu)于致密材料，但存在較小的微觀區(qū)域的不均勻性，所以，完全奧氏體化時(shí)間比相應(yīng)鍛件長(zhǎng)50%，在添加合金元素時(shí)，完全奧氏體化溫度會(huì)更高、時(shí)間會(huì)更長(zhǎng)。在粉末冶金材料的熱處理中，為了提高淬透性，通常加入一些合金元素如：鎳、鉬、錳、鉻、釩等，它們的作用跟在致密材料中的作用機(jī)理相同，可明顯細(xì)化晶粒，當(dāng)其溶于奧氏體后會(huì)增加過冷奧氏體的穩(wěn)定性，保證淬火時(shí)的奧氏體轉(zhuǎn)變，使淬火后材料的表面硬度增加，淬硬深度也增加。另外，粉末冶金材料淬火后都要進(jìn)行回火處理，回火處理的溫度控制對(duì)粉末冶金材料的的性能影響較大，因此要根據(jù)不同材料的特性確定回火溫度。</p><p> 粉末冶金基本知識(shí)綜合篇2017-12-25一、粉末的制造方法：1、氣噴霧法：常用于制造鋁粉、合金粉等易氧化之粉末，由于采用惰性氣體，所制造的粉末之純度高、外觀為球形且堆積度高。2、水噴霧法：水噴霧法所制得粉末之形狀較不規(guī)則，其缺點(diǎn)為其含氧量稍高。但其生產(chǎn)成本低。3、還原法：此法**普遍之金屬粉末為鐵粉，此種鐵粉是將氧化鐵FeO以氫氣還原而得。由于氧化鐵粉之密度較低且體積大，被還原后又會(huì)留下孔洞，所以其外形不規(guī)則且內(nèi)部有孔洞，俗稱海綿鐵粉。4、離心法：利用水或氣體之動(dòng)量將金屬熔液噴成粉末以外，亦可利用離心力原理將金屬熔液滴滴甩出。此法所制得的粉末雖然成本較高，但污染少、適合制作活性金屬，如鈦等。5、機(jī)械合金法：對(duì)于有些質(zhì)脆的金屬若撞擊可使之粉碎，所以只要經(jīng)過連續(xù)撞擊后即可得到較細(xì)且合乎規(guī)格的粉末。6、電解法：**常見的是電解銅及電解鐵粉。其純度高、壓縮性好、生胚強(qiáng)度好。其形狀為樹枝狀。但制造成本太高。粉末冶金制品已經(jīng)受到越多人的青睞。</p><div

如果運(yùn)用熔煉工藝生產(chǎn)不銹鋼制品的話，由于其切削加工的困難，會(huì)導(dǎo)致所制造的零件存在一系列的布置，比如尺寸精度差、表面粗糙不足等。而在解決類似難題的應(yīng)用中，粉末冶金起到了至關(guān)重要的作用。與傳統(tǒng)熔煉工藝生產(chǎn)的不銹鋼相比，粉末冶金不銹鋼具有所生產(chǎn)的零件接近凈成型、尺寸精度高、材料利用率高、結(jié)構(gòu)均勻等優(yōu)點(diǎn)，已廣泛應(yīng)用于機(jī)械、化工、船舶、汽車、儀器儀表等行業(yè)。但不是說粉末冶金不銹鋼就是完美的，由于其內(nèi)部容易存在孔隙，所以使得粉末冶金不銹鋼的力學(xué)性能、耐磨性和耐腐蝕性大為下降，從而嚴(yán)重的限制了這一h產(chǎn)品的應(yīng)用。但有研究已經(jīng)證明，粉末冶金不銹鋼幾乎所有的性能都隨著密度的增大而提高，所以說只要提高粉末冶金不銹鋼的密度，減少其孔隙度，就能對(duì)提高粉末冶金不銹鋼性能起到關(guān)鍵作用。粉末冶金不銹鋼內(nèi)部之所以會(huì)殘留大量空虛，與其采用固相燒結(jié)的方法有很大的關(guān)系，所以開始有用戶將其用超固相線液相燒結(jié)代替，使不銹鋼預(yù)合金粉末在燒結(jié)時(shí)形成液相，液相通過流動(dòng)填充孔隙進(jìn)而提高燒結(jié)體的致密度和性能。、不同于普通的液相燒結(jié)，超固相線液相燒結(jié)是對(duì)預(yù)合金粉的燒結(jié)，且在燒結(jié)過程中始終是單一相，燒結(jié)溫度將始終位于固相線和液相線之間。目前面向國(guó)內(nèi)外廣大用戶，提供質(zhì)量產(chǎn)品，產(chǎn)品早已跨出國(guó)門，邁向世界。金山區(qū)本地金屬注射成型服務(wù)至上</p><p

其也用于注射成型，通過氣體霧化生產(chǎn)的直徑約45μm球狀Nd-Fe-B粉末具有良好的流動(dòng)性。還有其他方法基于直接激光、電子束熔融或強(qiáng)制性磁粉層的燒結(jié)。對(duì)于永磁的主要應(yīng)用是制造Nd-Fe-B粉末的聚合物黏結(jié)復(fù)合材料。由于各向同性黏結(jié)磁體非常弱，磁能積約為5kJ?m?C3，故未使用六方晶系鐵氧體。成形件隨后以常規(guī)的方法磁化。這項(xiàng)工作還處于早期階段，有關(guān)稀土磁體的份研究報(bào)告可以追溯到2016年。大多數(shù)成果是關(guān)于各向同性的黏結(jié)磁體的，正如在引言中所討論的那樣，這不是一個(gè)有效利用昂貴的稀土材料的方法。其磁能積不超過58kJ?m?C3。迄今為止，通過激光熔化Nd-Fe-B粉末生產(chǎn)的致密磁體，其所得數(shù)值也不甚理想。關(guān)鍵是要找到一種方法。將粉末取向步驟引入增材制造過程。這種方法的優(yōu)點(diǎn)是可以在聚合物黏結(jié)磁體中產(chǎn)生形狀或密度的梯度變化，該磁體被設(shè)計(jì)用來生成理想的雜散場(chǎng)，盡管產(chǎn)生的磁場(chǎng)的量級(jí)很小，約為50kA?m?C1，但是可以在磁體內(nèi)部創(chuàng)建復(fù)雜的通道用于冷卻或其他流體的流動(dòng)。然而，當(dāng)前的一個(gè)巨大的挑戰(zhàn)是設(shè)計(jì)出一種不能通過傳統(tǒng)的壓制或注塑成型來制造的形狀，它具有獨(dú)特的、潛在有用的磁性功能。接下來，必須設(shè)計(jì)合適的磁化過程，以提供必要的三維磁化模式。普陀區(qū)質(zhì)量金屬注射成型質(zhì)量保證</p><p
