Embodiment 1
[0031] A heat treatment method for a diamond composite material blank, comprising the following steps:
[0032] 1) will follow figure 1 The assembled diamond composite material blank (size specification Φ1613mm) is placed in the vacuum furnace, and a batch of 200 diamond composite material blanks are placed in the same vacuum furnace;
[0033] 2) Vacuum the furnace so that the air pressure in the furnace reaches 7.5*10 -3 Below Pa, start to heat up slowly, heat from room temperature to 150°C in 30 minutes, and keep it warm for half an hour; then continue to vacuumize and heat up, and raise the temperature to 550°C in 1.5 hours, while the pressure in the furnace is stable at 4*10 -3 Below Pa;
[0034] 3) The temperature in the furnace is kept at 550°C for 1 hour, and at the same time, the vacuum furnace is intermittently filled with hydrogen and vacuumized, and the whole billet is degassed and reduced for heat treatment: first, a certain amount of hydrogen is charged into the...
Embodiment 2
[0038] A heat treatment method for a diamond composite material blank, comprising the following steps:
[0039] 1) will follow figure 1 The assembled diamond composite material blank (size specification Φ1913mm, 100 pieces) is placed in the vacuum furnace;
[0040] 2) Vacuum the furnace so that the air pressure in the furnace reaches 7*10 -3 Below Pa, start to heat up slowly, heat from room temperature to 150°C in 30 minutes, and keep it warm for half an hour; then continue to vacuumize and heat up, and raise the temperature to 580°C in 1.5 hours, while the pressure in the furnace is stable at 3*10 -3 Below Pa;
[0041] 3) The temperature in the furnace is kept at 580°C for 1 hour, while the vacuum furnace is intermittently filled with hydrogen and vacuumized, and the whole billet is degassed and reduced for heat treatment: first, a certain amount of hydrogen is charged into the vacuum furnace, and then The amount of hydrogen into the furnace makes the pressure in the furna...
Embodiment 3
[0045] A heat treatment method for a diamond composite material blank, comprising the following steps:
[0046] 1) will follow figure 1 The assembled diamond composite material blanks (size specification Φ1313mm, 400 pieces) are placed in the vacuum furnace;
[0047] 2) Vacuum the furnace so that the air pressure in the furnace reaches 6.5*10 -3 Below Pa, start to heat up slowly, heat from room temperature to 150°C (ie the first temperature) in 30 minutes, and keep it warm for half an hour; then continue to vacuumize and heat up, and heat up to 600°C (ie the second temperature) in 1.5 hours, At the same time, the air pressure in the furnace is stable at 3*10 -3 Below Pa;
[0048] 3) The temperature in the furnace is kept at 600°C for 1.5 hours, while the vacuum furnace is intermittently filled with hydrogen and vacuumized, and the whole billet is degassed and reduced for heat treatment: first, a certain amount of hydrogen is charged into the vacuum furnace, and the vacuum f...
