一、近二十年来粉末冶金技术发展的特点假若把粉末成形和烧结作为主要工艺的粉末冶金技术称之为传统的粉末冶金技术,那么近二十年来在粉末冶金领域发展起来的一系列新技术和新工艺的全部内容则称之为新型的粉末冶金技术。新型粉末冶金技术的发展有以下几个特点为:
First, the past two decades, the characteristics of the development of powder metallurgy technology If the powder metallurgy technology and powder forming and sintering as the main process known as the traditional powder metallurgy technology, then in the past two decades in the field of powder metallurgy developed a series of new technologies And the entire content of the new technology is called the new powder metallurgy technology. The development of new powder metallurgy technology has the following characteristics:
