粉末冶金材料是由几种金属粉末或金属与非金属粉末混合压制成型,并经过烧结而获得的材料。近10年来,粉末冶金工业发展迅速,它是一项颇具市场竞争力的少无切削金属加工方法,随着技术的不断进步,我国粉末冶金制品的产量明显增长。 1 铁基粉末冶金件的应用前景 由于长期缺乏对数量较大和附加值较高零件的需求,没有机会让粉末冶金行业发挥它特有的优势,因此,我国粉末冶金工业基础较为薄弱,一直都未受 Powder metallurgy material is composed of several kinds of metal powder or metal and non-metallic powder press molding, and obtained by sintering material. In recent 10 years, the rapid development of the powder metallurgy industry, it is a fairly competitive market with no cutting metal processing methods, with the continuous improvement of technology, China’s powder metallurgy products output increased significantly. 1 iron-based powder metallurgy application prospects Due to the long-term lack of large quantities and higher value-added parts of the demand, there is no opportunity for the powder metallurgy industry to play its unique advantages, therefore, China’s powder metallurgy industry foundation is weak, has not been subject to
