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。 </p> <p> 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，不銹鋼粉末冶金設(shè)備，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，不銹鋼粉末冶金設(shè)備，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，不銹鋼粉末冶金設(shè)備，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。

在粉末冶金領(lǐng)域，用純銅粉生產(chǎn)電子和導(dǎo)熱零部件。含有錫、鋅、鎳、或者鐵的銅合金被寬泛用于汽車(chē)、草地公園設(shè)備、工具和電子工業(yè)。銅粉多使用在自潤(rùn)滑軸承上，另外是Fe-Cu預(yù)混合，化學(xué)工業(yè)領(lǐng)域的滲析和摩擦材料部件。 </p> <p> 粉末冶金含油軸承一般來(lái)說(shuō)一次就能成形，基本不用切削加工。成本比機(jī)加工輕，材料浪費(fèi)也少，價(jià)格因此比較便宜。也符合現(xiàn)在提倡節(jié)約能源的國(guó)家政策,因此被認(rèn)為這是一個(gè)不會(huì)落伍的技術(shù)。粉末冶金含油軸承其基體里已經(jīng)用真空含浸的方法充滿(mǎn)了潤(rùn)滑油，并且在運(yùn)轉(zhuǎn)時(shí)由于溫升和泵吸的原因，其中的潤(rùn)滑油會(huì)滲出到運(yùn)轉(zhuǎn)表面，故可用于不另加潤(rùn)滑油的場(chǎng)合。粉末冶金含油軸承(含油軸承)是一類(lèi)孔隙中含浸有潤(rùn)滑油的多孔性合金制品。當(dāng)軸旋轉(zhuǎn)時(shí)，因軸與含油軸承之間的摩擦使含油軸承的溫度升高和泵吸作用。

在傳統(tǒng)的粉末冶金技術(shù)中，采用鐵基粉是常見(jiàn)的材料寬泛的用于汽車(chē)制造業(yè)。但是汽車(chē)生產(chǎn)的規(guī)模擴(kuò)大，鐵基粉的需求量也越來(lái)越大。 </p> <p> 用途 </p> <p> 粉末冶金技術(shù)的用途十分寬泛，可以用于信息領(lǐng)域。在信息領(lǐng)域主要是采用粉末冶金軟磁材料。軟磁材料可以分為金屬類(lèi)材料和鐵氧體材料。在早期先出現(xiàn)的是鐵氧體材料，這種材料的制造技術(shù) 相當(dāng)有限，所以現(xiàn)今也只能通過(guò)粉末冶金技術(shù)制造出來(lái)。軟磁材料中的金屬類(lèi)材料主要是用鐵和包含鐵的合金制造而成的，比如硅鋼和磷鐵等等。 </p></p><br /><p>文章來(lái)源地址:
