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。奉賢區(qū)本地金屬注射成型生產(chǎn)廠家以及加大熱塑性潤(rùn)滑劑的含量，從而提高了混合粉末的流動(dòng)性、填充性和成形性。</p><div

說到粉末冶金工藝技術(shù)以及材料，我們南方粉末冶金是再熟悉不過了，我們南方粉末冶金成立于1984年，至今已有30幾年的發(fā)展。在行業(yè)內(nèi)我們已經(jīng)是獨(dú)樹一幟，有著其他公司無法替代的地位。我們就來給大家簡(jiǎn)單講講粉末冶金工藝和傳統(tǒng)的冶金工藝有哪些突出的優(yōu)點(diǎn)。1、我們粉末冶金工藝是在低于基體金屬的熔點(diǎn)下進(jìn)行的，因此可以獲得熔點(diǎn)、密度相差懸殊的多種金屬、金屬與陶瓷、金屬與塑料等多相不均質(zhì)的特殊功能復(fù)合材料和制品。2、另一方面我們提高了材料性能。用特殊方法制取的細(xì)小金屬或合金粉末，凝固速度極快、晶粒細(xì)小均勻，保證了材料的均勻，性能穩(wěn)定，以及良好的冷、熱加工性能，且粉末顆粒不受合金元素和含量的限制，可提**化相含量，從而發(fā)展新的材料體系。3、一點(diǎn)是利用各種成形工藝，我們可以將粉末原料直接成形為少余量、無余量的毛坯或凈形零件，很重要的一點(diǎn)就是大量減少機(jī)加工量。提高材料利用率，降低成本。我們一般的粉末冶金的品種繁多，主要有：鎢等難熔金屬及合金制品；；硬質(zhì)合金，用于制造切削和耐磨中的鉆頭、車刀、銑刀，還可制造模具等；Cu合金、不銹鋼及Ni等多孔材料，用于制造燒結(jié)含油軸承、燒結(jié)金屬過濾器及紡織環(huán)等。隨著粉末冶金生產(chǎn)技術(shù)的發(fā)展。</p><p> 降低回火脆性的影響，一般的材料可在175-250℃下空氣或油中回火。2、化學(xué)熱處理工藝化學(xué)熱處理一般都包括分解、吸收、擴(kuò)散三個(gè)基本過程，比如，滲碳熱處理的反應(yīng)如下：2CO≒[C]+CO2(放熱反應(yīng))CH4≒[C]+2H2(吸熱反應(yīng))碳分解出后被金屬表面吸收并逐漸向內(nèi)部擴(kuò)散，在材料的表面獲得足夠的碳濃度后再進(jìn)行淬火和回火處理，會(huì)提高粉末冶金材料的表面硬度和淬硬深度。由于粉末冶金材料的孔隙存在，使得活性炭原子從表面滲入內(nèi)部，完成化學(xué)熱處理的過程。但是，材料密度越高，孔隙效應(yīng)就越弱，化學(xué)熱處理的效果就越不明顯，因此，要采用碳勢(shì)較高的還原性氣氛保護(hù)。根據(jù)粉末冶金材料的孔隙特點(diǎn)，其加熱和冷卻速度要低于致密材料，所以加熱時(shí)要延長(zhǎng)保溫時(shí)間，提高加熱溫度。粉末冶金材料的化學(xué)熱處理包括滲碳、滲氮、滲硫和多元共滲等幾種形式，在化學(xué)熱處理中，淬硬深度主要與材料的密度有關(guān)。因此，可以在熱處理工藝上采取相應(yīng)措施，比如：滲碳時(shí)，在材料密度大于7g/cm3時(shí)適當(dāng)延長(zhǎng)時(shí)間。通過化學(xué)熱處理可提高材料的耐磨性，粉末冶金材料的不均勻奧氏體滲碳工藝，使處理后的材料滲層表面的含碳量可達(dá)2%以上，碳化物均勻分布于滲層表面，能夠很好地提高硬度和耐磨性能。引進(jìn)CAD計(jì)算機(jī)輔助設(shè)計(jì)和ERP信息管理系統(tǒng)及國(guó)內(nèi)先進(jìn)生產(chǎn)設(shè)備和檢測(cè)設(shè)備。</p><div
