Abstract: |
Effect of loads on high-speed fiction and wear properties of recycled WCP/Fe-C functional composites were investigated by MMS-1G high-speed pin-dish friction-wear tester and TEM at the sliding velocities of 60m/s and 80m/s in present work. Wear mechanism for the recycled functional composites was discussed under the testing condition. The results showed that the wear rates of the recycled functional composites under the two sliding velocities increased with the increasing load, and their friction coefficients decreased with increase of the loads. Under same load, the wear rate for the recycled functional composites was higher at the sliding velocity of 80m/s than that of at the sliding velocity of 60m/s, and the friction coefficient was lower at 80m/s than at 60m/s. Wear mechanism of the recycled functional composites were mainly micro- cutting wearing, grain wearing, surface peeling off at lower loads and oxidation wear and fatigue wear, which is accompanied by adhesive wear at higher load.
