Abstract

The invention relates to the use of an oxide dispersion strengthened Co powder as a binder in the manufacture of diamond tools by pressure sintering. The invention concerns a process for making oxide dispersion strengthened Co powder whereby the oxide is fine and homogeneously distributed in the Co powder. The presence of the oxide avoids excessive grain growth during sintering at high temperatures keeping the hardness sufficiently high.
