粉末冶金是什么意思?

發布:安陽坤鑫達冶金耐材有限公司瀏覽:1184次

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,經過成形和燒結,制造金屬材料、復合材料以及各種類型制品的工藝技術。粉末冶金法與生產陶瓷有相似的地方,均屬于粉末燒結技術,因此,一系列粉末冶金新技術也可用于陶瓷材料的制備。由于粉末冶金技術的優點,它已成為解決新材料問題的鑰匙,在新材料的發展中起著舉足輕重的作用。

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遠超出材料和冶金的范疇,往往是跨多學科(材料和冶金,機械和力學等)的技術。尤其現代金屬粉末3D打印,集機械工程、CAD、逆向工程技術、分層制造技術、數控技術、材料科學、激光技術于一身,使得粉末冶金制品技術成為跨更多學科的現代綜合技術。
