class="page-proshow02"><p class="title">詳細說明</p><div id="24zl24s" class="box"><p><p> 粉末冶金制品的種類又具有多樣性，從而滿足各生產(chǎn)行業(yè)的專業(yè)化的生產(chǎn)需求。粉末冶金制品的主體結(jié)構(gòu)材質(zhì)是采用碳鋼噴塑或鍍鋅材料及表面處理技術制作而成，為了適應一些特殊場合，如潔凈室以及食品加工等行業(yè)的需求，粉末冶金加工制品的生產(chǎn)材質(zhì)還采用不銹鋼材質(zhì)，并且嚴格執(zhí)行相關的安全標準。所以我國在未來的粉末冶金零件的發(fā)展目標也就變得更加明確，通過各種有利因素為行業(yè)的發(fā)展提供更加便利的條件，在政策方面，齒輪粉末冶金設備，我國當前對節(jié)能減排以及降耗方面的重視，齒輪粉末冶金設備，齒輪粉末冶金設備，將對汽車粉末冶金產(chǎn)品的發(fā)展提供較好的條件，隨著粉末冶金技術的不斷進步，其成本較低的優(yōu)勢將伴隨著汽車行業(yè)的成本競爭加劇而日趨明顯。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="齒輪粉末冶金設備" src="https://tyunfile.71360.com/UploadFile/lmfmyj/637249885493642578/8160048.jpg"></div><p> 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，降低回火脆性的影響，一般的材料可在175-250℃下空氣或油中回火0.5-1.0h。 </p> <p> 2、化學熱處理工藝 </p> <p> 化學熱處理一般都包括分解、吸收、擴散三個基本過程，比如，滲碳熱處理的反應如下： </p> <p> 2CO≒[C]+CO2 (放熱反應) </p> <p> CH4≒[C]+2H2 (吸熱反應) </p><div style="width:100%;text-align: center;"><img style="max-width:

粉末冶金的應用領域：考慮到車輛節(jié)能、輕量化及產(chǎn)品精度化的訴求，伴隨未來粉末冶金生產(chǎn)企業(yè)規(guī)模做大，技術加強和依舊強勁的成本優(yōu)勢，車用粉末冶金零件進口替代趨勢下的需求增長仍將持續(xù)發(fā)生。 </p> <p> 粉末冶金相關企業(yè)主要是適用于汽車行業(yè)、裝備制造業(yè)、金屬行業(yè)、儀器儀表、五金工具、電子家電等領域的零配件生產(chǎn)和研究，相關原料、輔料生產(chǎn)，各類粉末制備設備、燒結(jié)設備制造。 </p> <p> 產(chǎn)品包括軸承、齒輪、硬質(zhì)合金工具、模具、摩擦制品等等。粉末冶金汽車零件近年來已成為粉末冶金行業(yè)的市場，約50%的汽車零部件為粉末冶金零部件。 </p></p><br /><p>文章來源地址: http://www.cdcfah.com/cp/423223.html</p></div></div></div></div></div><div id="vk7kmt8"
