class="page-proshow02"><p class="title">詳細說明</p><div id="u39cb4a" class="box"><p><p> 當今新材料及其制備技術的發(fā)展趨勢具有以下幾個特點： </p> <p> （1）新材料粉末冶金技術是現(xiàn)代工業(yè)和高技術發(fā)展中的共性關鍵技術，聯(lián)銘粉末冶金齒輪，材料科學技術已成為當代和下世紀重要的、發(fā)展快的科學技術之一。信息、能源、農(nóng)業(yè)和先進制造等技術領域的發(fā)展都離不開新材料及其制備技術的發(fā)展； </p> <p> （2）綜合利用現(xiàn)代先進科學技術成就，多學科交叉，知識密集，導臻新材料及其制備技術的投資強度大、更新?lián)Q代快，經(jīng)濟效益和社會效益巨大； </p> <p> （3）新材料的制備和質(zhì)量的提高更加依賴于新技術、新工藝的發(fā)展和精確的檢測控制技術的應用，聯(lián)銘粉末冶金齒輪。對制備技術的重視與投入直線上升，極大地加速了基礎材料的發(fā)展和傳統(tǒng)產(chǎn)業(yè)的改造，聯(lián)銘粉末冶金齒輪。 </p> <p> （4）對材料基礎性、先導性的認識已形成共識。材料的研帛和發(fā)展既要與器件的研帛密切配合，又要注意到自身的系統(tǒng)性和超前性，這樣才有利于材料實現(xiàn)跨躍發(fā)展。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="聯(lián)銘粉末冶金齒輪" src="https://tyunfile.71360.com/UploadFile/lmfmyj/637249885633291016/5569944.jpg"></div><p> 我國粉末冶金制品行業(yè)上世紀50年代中期起步，后隨著汽車工業(yè)的發(fā)展，加上自身具有的節(jié)材性，日益受到重視。目前，我國粉末冶金零件產(chǎn)量已進入高速發(fā)展期。近些年來，由于一些新技術的興起,如機械合金化、金屬粉末注射成形、溫壓成形、噴射成形、微波燒結(jié)、放電等離子燒結(jié)、自蔓延高溫合成、燒結(jié)硬化等,使得粉末冶金材料和技術得到了各國的普遍重視，其應用也越來越寬泛。目前，粉末冶金技術正向著高致密化、高性能化、集成化和低成本等方向發(fā)展。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="聯(lián)銘粉末冶金齒輪" src="https://tyunfile.71360.com/UploadFile/lmfmyj/637249885632832031/5761550.jpg"></div><p> 由于粉末冶金工藝在材料生產(chǎn)過程中并不熔化材料，也就不怕混入由坩堝和脫氧劑等帶來的雜質(zhì)，而燒結(jié)一般在真空和還原氣氛中進行，不怕氧化，也不會給材料任何污染，故有可能制取高純度的材料。 </p> <p> 很多新興金屬材料的制作研發(fā)與粉末冶金密切相關。粉末冶金是以金屬粉末為原料，經(jīng)過成型和固結(jié)，制造金屬材料、復合材料及制品的工藝過程。高性能金屬粉末的開發(fā)與生產(chǎn)，對提高粉末冶金材料和制品性能、推動粉末冶金技術進步起著至關重要的作用。 </p></p><br /><p>文章來源地址:
