Abstract
Diamond powder can be successfully cemented with cobalt. At 62 kilobars the sintering occurs over the temperature range from 1570 degrees to 1610 degrees C. The maximum microhardness of the compact ( 3000 kilograms per square millimeter on the Knoop scale) is obtained with a mixture of 20 percent cobalt (by volume) and a diamond particle size of 1 to 5 micrometers.
摘要
金刚石粉末可用钴来成功地烧结。在 620 千巴压力下，烧结温度范围为 1570°C 到 1610°C。当钴的混合比（按体积计）为 20%，金刚石粒度为 1 到 5 微米时，压块的最大显微硬度（努普硬度计上为 3000 千克/平方毫米）达到最高值。
