Cemented carbide is an ideal material for wear-resistant parts. However, traditional cemented carbide products can no longer meet the increasingly stringent usage requirements. In recent years, the use of cryogenic treatment technology to make up for the shortcomings in wear resistance of traditional carbide tools has attracted widespread attention. Jiang et al. used the pin-on-disk friction and wear method to measure the change in the wear amount of YG8 cemented carbide before and after cryogenic treatment.
The results showed that the ratio between the wear amount of the cemented carbide sample after cryogenic treatment and the wear amount of the diamond abrasive parts was from 6.41 reduced to 4.02, which shows that cryogenic treatment improves the wear resistance of cemented carbide. Gao et al. used the ring-block friction and wear method to measure the changes in wear resistance of WC-Fe-Ni cemented carbide before and after cryogenic treatment. The results showed that after cryogenic treatment, the wear rate and friction coefficient of WC-Fe-Ni cemented carbide were respectively Reduced by 56% and 17.2%.
Gill et al. used the pin-on-disk friction and wear method to measure the wear resistance of P25 cemented carbide after cryogenic treatment at -110°C and -196°C. The results showed that both treatment methods significantly improved the wear resistance of the cemented carbide. Wear resistance, and the lower the cryogenic treatment temperature, the higher the improvement in wear resistance of the material. The test results also show that the cryogenic treatment temperature has a great influence on the improvement of the wear resistance of cemented carbide.
