摘要
The present invention relates to the use of a pre-alloyed powder as a binder in the manufacture of diamond tools by hot sintering. This powder is characterized in that it has an average particle size of less than 10 mum as measured with the Fisher SSS and loss of mass by reduction in hydrogen of less than 2% as measured according to the standard ISO 4491-2:1989 and in that it contains, in % by weight, up to 40% of cobalt, up to 50% of nickel, from 5 to 80% of iron and from 5 to 80% of copper; the other components in the powder consist of unavoidable impurities.
