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，它們在取代低密度、低硬度和強度的鑄鐵材料方面已經(jīng)具有明顯優(yōu)勢。粉末冶金材料的熱處理有淬火、化學熱處理、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，淬透性相對較差。另外淬火時，粉末材料的燒結(jié)密度和材料的導熱性是成正比關(guān)系的;粉末冶金材料因為燒結(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，完全奧氏體化時間比相應(yīng)鍛件長50%，在添加合金元素時，完全奧氏體化溫度會更高、時間會更長。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理相同，可明顯細化晶粒，當其溶于奧氏體后會增加過冷奧氏體的穩(wěn)定性，保證淬火時的奧氏體轉(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行回火處理，回火處理的溫度控制對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。金山區(qū)質(zhì)量金屬注射成型還需要在粉末中需要加入較多的粘結(jié)劑。</p><div

粉末冶金是制取金屬或用金屬粉末（或金屬粉末與非金屬粉末的混合物）作為原料，經(jīng)過成形和燒結(jié)，制造金屬材料、復(fù)合以及各種類型制品的工藝技術(shù)。粉末冶金的優(yōu)勢：1.粉末冶金技術(shù)可以限度地減少合金成分偏聚，消除粗大、不均勻的鑄造。2.可以容易地實現(xiàn)多種類型的復(fù)合，充分發(fā)揮各組元材料各自的特性，是一種低成本生產(chǎn)高性能金屬基和陶瓷復(fù)合材料的工藝技術(shù)。3.可以實現(xiàn)凈近形成形和自動化批量生產(chǎn)，從而，可以有效地降低生產(chǎn)的資源和能源消耗。4.可以充分利用礦石、尾礦、煉鋼污泥、軋鋼鐵鱗、回收廢舊金屬作原料，是一種可有效進行材料再生和綜合利用的新技術(shù)。5.可以生產(chǎn)普通熔煉法無法生產(chǎn)的具有特殊結(jié)構(gòu)和性能的材料和制品。粉末冶金制品的應(yīng)用范圍十分，從普通機械制造到精密儀器；從五金工具到大型機械硬質(zhì)合金機械成型機；從電子工業(yè)到電機制造；從民用工業(yè)到工業(yè)；從一般技術(shù)到高技術(shù)，均能見到粉末冶金工藝的身影。以上就是關(guān)于粉末冶金制品的相關(guān)特點及用途，希望此信息能對您了解粉末冶金制品有所幫助。提供專業(yè)粉末冶金制品的加硬、發(fā)黑、防銹，電鍍。</p><div
