Embodiment 1
[0023] Step (1): After raising the TiC-Co cemented carbide from room temperature to 500°C at a rate of 3°C / min in 1,2-butanediol atmosphere, keep it warm for 30 minutes, and then increase the temperature at a rate of 2°C / min After rising to 1250°C, keep warm for 40 minutes; among them, the feeding rate of 1,2-butanediol is 128 drops / min,
[0024] Step (2): Then pass liquid nitrogen for rapid cooling treatment, until 230 ° C, pass nitrogen or argon for 30 minutes, and then naturally cool to room temperature to prepare heat-treated TiC-Co cemented carbide.
[0025] Result after testing: The density of YG06 product after heat treatment is 14.68g / cm 3 , hardness 93.5HRA.
