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(lái)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(guò)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>

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(guò)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(guò)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(guò)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。徐匯區(qū)原裝金屬注射成型誠(chéng)信合作</p><p
