与传统的模压、烧结技术相比 ,采用 90年代发展起来的温压和模壁润滑技术可使粉末冶金制品的密度各提高 0 2ｇ ｃｍ3 左右 ,美国盖士巴尔公司的ＴＯＰＳ温压系统综合利用了以上两种新技术 ,可利用传统的粉末冶金设备通过一次压制、一次烧结提高粉末冶金制品的密度。采用这种工 Compared with the traditional molding and sintering technology, the temperature and pressure and mold wall lubrication technology developed in the 1990s can make the density of powder metallurgy products increase by about 0 2g cm3, and the gas pressure and pressure system of the Gasstall Company in the United States comprehensively utilized The above two new technologies can utilize the traditional powder metallurgy equipment to improve the density of the powder metallurgy products through one-time pressing and one-time sintering. Use this kind of work
