Description

粉末冶金方法
技术领域
本发明涉及一种粉末冶金方法。
背景技术
粉末冶金是制取金属粉末或用金属粉末(或金属粉末与非金属粉末的混合物)作为原料，经过成形和烧结，制造金属材料、复合材料以及各种类型制品的工艺技术。粉末冶金法与生产陶瓷有相似的地方，均属于粉末烧结技术，因此，一系列粉末冶金新技术也可用于陶瓷材料的制备。由于粉末冶金技术的优点，它已成为解决新材料问题的钥匙，在新材料的发展中起着举足轻重的作用。粉末冶金包括制粉和制品。其中制粉主要是冶金过程，和字面吻合。而粉末冶金制品则常远远超出材料和冶金的范畴，往往是跨多学科(材料和冶金，机械和力学等)的技术。尤其现代金属粉末3D打印[1-2]，集机械工程、CAD、逆向工程技术、分层制造技术、数控技术、材料科学、激光技术于一身，使得粉末冶金制品技术成为跨更多学科的现代综合技术。现有的粉末冶金材料寿命短。
