id="tsp22hw" class="box"><p><p> 在了解粉末冶金技術(shù)的過程中，我們接觸到了金屬粉末注射成形工藝，沒想到它完全不同于普通的成形技術(shù)，在大批量制造具有復(fù)雜幾何形狀、高性能、高精度的零件方面一定都沒有難度，從而促使粉末冶金企業(yè)的產(chǎn)業(yè)化取得突破性進展。粉末冶金企業(yè)在進行金屬粉末注射成形的時候，除了需要準(zhǔn)備好加工所需的相應(yīng)粉末，還需要在粉末中需要加入較多的粘結(jié)劑。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，靜安區(qū)直銷金屬注射成型找哪家。其中粉末需用≤10um的超細近球形粉，而且從混料到脫脂、燒結(jié)，工序較復(fù)雜，工藝要求嚴(yán)格，特別是需要較長的脫脂和燒結(jié)時間，這也是造成粉末冶金企業(yè)制造成本偏高的主要原因。而粘結(jié)劑的狼一定要充足，否則很難達到相應(yīng)的性能。對此粉末冶金企業(yè)研制出了一種簡化辦法，就是流動溫壓成形技術(shù)，它是在金屬粉末溫壓的基礎(chǔ)上，結(jié)合了金屬粉末注射成形工藝的優(yōu)點；然后通過加入適量的粗粉和微細粉末，以及加大熱塑性潤滑劑的含量，從而提高了混合粉末的流動性、填充性和成形性。由于在壓制時混合粉末變成了具有良好流動性的粘流體，所以它不僅有液體的優(yōu)點，又有很高的粘度并減小摩擦力，才會使壓制壓力在粉末中分布均勻，靜安區(qū)直銷金屬注射成型找哪家，還得到了很好的傳遞，靜安區(qū)直銷金屬注射成型找哪家。由于這一點。又有很高的粘度并減小摩擦力，才會使壓制壓力在粉末中分布均勻，還得到了很好的傳遞。由于這一點。靜安區(qū)直銷金屬注射成型找哪家</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(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，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(dǎo)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(dāng)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。結(jié)合了金屬粉末注射成形工藝的優(yōu)點；然后通過加入適量的粗粉和微細粉末。</p><div
