1.復(fù)壓為提高燒結(jié)體物理和力學(xué)性能而進(jìn)行的施加壓力處理，包括精整和整形等。精整是為達(dá)到所需尺寸而進(jìn)行的復(fù)壓，通過(guò)精整模對(duì)燒結(jié)體施壓以提高精度。整形是為達(dá)到特定的表面形狀而進(jìn)行的復(fù)壓，通過(guò)整形模對(duì)制品施壓以校正變形且降低表面粗糙度值。復(fù)壓適用于要求較高且塑性較好的制品，如鐵基、銅基制品。2.浸漬用非金屬物質(zhì)(如油、石蠟和樹(shù)脂等)填充燒結(jié)體孔隙的方法。常用的浸漬方法有浸油、浸塑料、浸熔融金屬等。浸油即在燒結(jié)體內(nèi)浸入潤(rùn)滑油，改善其自潤(rùn)滑性能并防銹，常用于鐵、銅基含油軸承。浸塑料是采用聚四氟乙烯分散液，經(jīng)固化后，實(shí)現(xiàn)無(wú)油潤(rùn)滑，常用于金屬塑料減摩零件。浸熔融金屬可提**度及耐磨性，鐵基材料常采用浸銅或鉛。3.熱處理對(duì)燒結(jié)體加熱到一定溫度，再通過(guò)控制冷卻方法等處理，以改善制品性能的方法。常用的熱處理方法有淬火、化學(xué)熱處理、熱機(jī)械處理等，工藝方法一般與致密材料相似。對(duì)于不受沖擊而要求耐磨的鐵基制件可采用整體淬火，由于孔隙的存在能減少內(nèi)應(yīng)力，一般可以不回火。而要求外硬內(nèi)韌的鐵基制件可采用淬火或滲碳淬火。熱鍛是獲得致密制件常用的方法，熱鍛造的制品晶粒細(xì)小，且強(qiáng)度和韌性高。松江區(qū)便宜金屬注射成型生產(chǎn)廠家由于在壓制時(shí)混合粉末變成了具有良好流動(dòng)性的粘流體，所以它不僅有液體的優(yōu)點(diǎn)。</p><div

磁能積為515kJ?m?C3）和BaFe12O19（磁能積為45kJ?m?C3）之間的巨大差距而探索新的高性能無(wú)稀土磁性材料的嘗試一直不太成功。六方晶鐵氧體產(chǎn)量巨大，約為1×106t?a?C1，它與稀土磁體共享市場(chǎng)份額。倘若能找到一種滿足嚴(yán)格性?xún)r(jià)比標(biāo)準(zhǔn)的材料，即每焦耳磁能的成本不超過(guò)1美元，那么就有機(jī)會(huì)用一種新的“間隙磁鐵”來(lái)填補(bǔ)這一空白?，F(xiàn)已提出的許多化合物都含有其他昂貴的元素，如鉍、鎵或釔。而其他化合物的各向異性不足。（二）增材制造近幾年材料工程學(xué)的創(chuàng)新是3D打印技術(shù)（即增材制造），如今這種技術(shù)被應(yīng)用于一次性產(chǎn)品，或者具有簡(jiǎn)單或復(fù)雜形狀的小批量物體的原型設(shè)計(jì)與制造。在計(jì)算機(jī)控制下，打印機(jī)利用聚合或金屬原料。建立一個(gè)由二維層級(jí)依次沉積和固結(jié)而成的形狀。這些層級(jí)可由光固或熱固聚合物、含有陶瓷或金屬粉末的聚合物、通過(guò)激光熔化或燒結(jié)作用熔合的金屬粉末制成。生產(chǎn)黏結(jié)磁體的方法包括黏接劑噴射法，每一層磁粉都覆有一層液體熱固性黏結(jié)劑，然后在烘箱中固化打印體。熔融擠出法通常用預(yù)混磁粉和高分子黏結(jié)劑制成的細(xì)絲為原料，使之熔化并從移動(dòng)頭中擠出以建立層級(jí)。一種變體將復(fù)合材料球團(tuán)用于大面積增材制造。該聚合物通常是聚酰胺（尼龍）。</p><p> 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(lèi)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(chē)、儀器儀表等行業(yè)。但不是說(shuō)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(shuō)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(kāi)始有用戶(hù)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(guò)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(guò)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。其中粉末需用≤10um的超細(xì)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。</p><div
