Embodiment 1
[0027] 1) The surface of the QT600 friction pair is textured by a laser marking machine, and 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, use metallographic sandpaper to remove burrs.
[0028] 2) Disperse 4 g of polytetrafluoroethylene (PTFE) and 1 g of catalyst powder into 100 mL of anhydrous ethanol solution, use a probe-type ultrasonic processor for ultrasonic treatment for 5 min, then quickly filter out the mixed powder, and dry it at 80 °C to remove residual residues. ethanol to obtain a homogeneously mixed powder.
[0029] 3) Spread the evenly mixed powder evenly on the surface of the textured friction pair, cover with a layer of weighing paper, and load 10 MPa on the tablet press for 10 minutes to obtain a pre-pressed friction pair.
[0030] 4) Move the pre-pressed friction pair into a muffle furnace, calcine at 350 ...
Embodiment 2
[0034] 1) The surface of the QT600 friction pair is textured by a laser marking machine, and 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 marking, use metallographic sandpaper to remove burrs.
[0035] 2) Disperse 3 g of polytetrafluoroethylene (PTFE) and 2 g of catalyst powder into 100 mL of anhydrous ethanol solution, ultrasonically treat with a probe-type ultrasonic processor for 5 min, then quickly filter out the mixed powder, and dry it at 80 °C to remove residual. ethanol to obtain a homogeneously mixed powder.
[0036] The remaining steps are the same as in Example 1.
[0037] Tribological test conditions are the same as Example 1. The test results are shown in Table 1: the average friction coefficient of the untreated QT600 friction pair is 0.15, and the wear rate is 4.14×10 -6 mm 3 / N*m; in this example, the tribological propertie...
Embodiment 3
[0039] 1) The surface of the friction pair coated with Ni-P coating is textured by a laser marking machine, and the texture shape is processed into a long strip with a texture width of 85 μm, a texture spacing of 200 μm, and a texture depth of 35 μm. , The laser marking power is 4.5W, and after the marking treatment, it is polished with metallographic sandpaper to remove burrs.
[0040] 2) Disperse 1.8g of polytetrafluoroethylene (PTFE) and 1.2g of catalyst powder into 100mL of anhydrous ethanol solution, ultrasonically treat it with a probe-type ultrasonic processor for 5 minutes, then quickly filter out the mixed powder, and dry it at 80 °C to remove Residual ethanol, resulting in a homogeneously mixed powder.
[0041] The remaining steps are the same as in Example 1.
[0042] The sample disc under the tribological test is the sample after the Ni-P coating treatment in this example, and other friction conditions are the same as Example 1. The test results are shown in Tabl...
