銅基粉末冶金的孔隙率高，孔隙均勻而光滑，所以它的初始阻力小，易于反吹；而且再生能力強(qiáng)，使用時(shí)間長(zhǎng)，特別適用于流體分布、均勻化處置等均勻性要求較高的場(chǎng)所。另外，銅基粉末的機(jī)械強(qiáng)度高、剛性好、塑性好、抗氧化、耐腐蝕等，應(yīng)用更為寬泛。行業(yè)面對(duì)的問(wèn)題和挑戰(zhàn)：(1)針對(duì)傳統(tǒng)汽車(chē)的**粉末冶金零件的需求，我們將如何提高粉末冶金制品的技術(shù)水平，如何提升粉末冶金零件的質(zhì)量水平以滿足**需求？

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(jī)理相同，可明顯細(xì)化晶粒，當(dāng)其溶于奧氏體后會(huì)增加過(guò)冷奧氏體的穩(wěn)定性，保證淬火時(shí)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(jìn)行回火處理，回火處理的溫度控制對(duì)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(xué)熱處理工藝 </p> <p> 化學(xué)熱處理一般都包括分解、吸收、擴(kuò)散三個(gè)基本過(guò)程，比如，滲碳熱處理的反應(yīng)如下： </p> <p> 2CO≒[C]+CO2 (放熱反應(yīng)) </p> <p> CH4≒[C]+2H2 (吸熱反應(yīng)) </p><div
