1，奉化粉末冶金原理、單向壓制單向壓制工作原理：陰模型腔和下模沖的位置固定不動(dòng)，上模沖在壓機(jī)凸輪帶動(dòng)下，向下進(jìn)入陰模型腔，并對(duì)陰模型腔的粉末加壓，使粉末壓制成具有一定密度和強(qiáng)度的坯件。 </p> <p> 單向壓制的一個(gè)循環(huán)有以下步驟：A粉末充填：粉末通過手工或者動(dòng)送粉器的送粉，利用粉末重力充填在陰模型腔中。B單向壓制：粉末填充完畢后，陰模型腔與下模沖位置固定不變，上模沖在壓機(jī)凸輪帶動(dòng)下，向下進(jìn)入陰模型腔，使粉末壓制成成具有一定密度和強(qiáng)度的坯件。C保壓：為了使壓力得到有效傳遞，奉化粉末冶金原理，使坯件密度分布均勻，上模沖應(yīng)在180度的成型壓制位置下保持不動(dòng)一段時(shí)間，使坯件中空氣有足夠時(shí)間逸出。D脫模：保壓結(jié)束后，上模沖由壓機(jī)凸輪復(fù)位帶動(dòng)向上脫離陰模型腔，下模沖則由壓機(jī)的下氣缸的作用力作用下把坯件頂出陰模型腔。E復(fù)位：上模沖退到高點(diǎn)，奉化粉末冶金原理，送粉器把壓制的坯件推出，同時(shí)下模沖退回固定位置，同時(shí)粉末在重力作用下充填在陰模型腔中。

統(tǒng)計(jì)數(shù)字顯示，近5年我國(guó)粉末冶金制品銷量平均年增長(zhǎng)率為15.4%，銷售收入平均年增長(zhǎng)率為16.2%。2013年，我國(guó)粉末冶金機(jī)械零部件合計(jì)銷量已達(dá)15.7萬噸。 </p> <p> 目前市場(chǎng)上的剎車材料以灰鑄鐵和粉末冶金為主，碳/陶屬于新一代剎車材料。國(guó)際上起步較早的布雷博等公司使用的是短纖維碳/陶。長(zhǎng)纖維和短纖維相比有三大優(yōu)勢(shì)，從編織上來說，短纖維是雜亂無章的，長(zhǎng)纖維是一體的，因此結(jié)構(gòu)強(qiáng)度更大，不易破損；第二從結(jié)構(gòu)外形來說，長(zhǎng)纖維碳/陶可實(shí)現(xiàn)結(jié)構(gòu)、尺寸上任意設(shè)計(jì)，可滿足個(gè)性化定制；第三從性能來說，長(zhǎng)纖維碳/陶起溫快，在低溫下剎車性能更優(yōu)異。

粉末冶金是制取金屬粉末或用金屬粉末（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)合材料以及各種類型制品的工藝技術(shù)。粉末冶金法與生產(chǎn)陶瓷有相似的地方，均屬于粉末燒結(jié)技術(shù)，因此，一系列粉末冶金新技術(shù)也可用于陶瓷材料的制備。由于粉末冶金技術(shù)的優(yōu)點(diǎn)，它已成為解決新材料問題的鑰匙，在新材料的發(fā)展中起著舉足輕重的作用。 </p> <p> 粉末冶金包括制粉和制品。其中制粉主要是冶金過程，和字面吻合。而粉末冶金制品則常遠(yuǎn)遠(yuǎn)超出材料和冶金的范疇，往往是跨多學(xué)科（材料和冶金，機(jī)械和力學(xué)等）的技術(shù)。尤其現(xiàn)代金屬粉末3D打印，集機(jī)械工程、CAD、逆向工程技術(shù)、分層制造技術(shù)、數(shù)控技術(shù)、材料科學(xué)、激光技術(shù)于一身，使得粉末冶金制品技術(shù)成為跨更多學(xué)科的現(xiàn)代綜合技術(shù)。
