Embodiment 1
[0032] 1) Use a laser marking machine to texture the surface of the QT600 friction pair. The texture shape is processed into a long strip, the texture width is 85 μm, the texture spacing is 200 μm, the texture depth is 35 μm, and the laser marking power is 4.5 W, After texture treatment, sand with metallographic sandpaper to remove burrs.
[0033] 2) Disperse 4 g of polytetrafluoroethylene (PTFE) and 1 g of catalyst powder into 100 mL of absolute ethanol solution, use a probe-type ultrasonic processor to sonicate for 5 min, then quickly filter out the mixed powder, and dry at 80 ° C to remove residual ethanol to obtain a homogeneously mixed powder.
[0034] 3) Evenly spread the uniformly mixed powder on the surface of the friction pair after the texture treatment, and cover with a layer of weighing paper, load 10 MPa on the tablet press and hold the pressure for 10 minutes to obtain the pre-pressed friction pair.
[0035] 4) Move the pre-pressed friction pair into a muffle fu...
