FIELD: metallurgy.
SUBSTANCE: method includes plasticizing hard-alloy powder mixture, filling the metal mold with the end charge, compressing the charge to briquettes, laying diamond monocrystal onto the briquette surface and sintering the briquette with the diamond monocrystal soaked in low-melting metal or an alloy in the upward direction. Herein a layer of plasticized fine chrome powder with the thickness of 0.3-2 mm is formed on the end of the briquette, diamond laying is produced on top of the finished layer of plasticized fine chrome powder on the briquette end surface, and the briquette sintering is conducted at the temperature not higher than 1100 °C with the holding time of not greater than 5 minutes.
EFFECT: increased strength and reliability of the compound of diamond monocrystal with the tool metal base.
