Embodiment 1
[0016] Take by weight 30 parts of copper powder, totally 60 parts of titanium powder and carbon powder (the mol ratio of titanium powder and carbon powder should be 1: 1), 5 parts of graphite, 5 parts of aluminum; Drying and degassing under high temperature and vacuum conditions, and then ball milling to mix evenly; then use molding (pressure between 10 ~ 200Mpa) to press into a φ12 cm blank; put the pressed blank into the mold, vacuumize and ignite the compact ; After the compact is completely burned and still in a semi-molten state, use a press to apply pressure to the blank through the mold. Since there is no air, a high-density cermet self-lubricating wear-resistant material can be obtained. Of course, if necessary, some other substances such as boron nitride can also be added.
[0017] The obtained wear-resistant material is detected, the three-point bending strength of the wear-resistant material reaches 1050MPa, the crush strength is 1500MPa, the friction coefficient is...
