Effect of Reciprocating Wear Frequency on Tribological Properties and Friction-Induced Vibration and Noise of 42CrMo-Based Hydraulic Cylinder

Heavy loads and fatigue wear of the contact areas between the hydraulic cylinder block and the sealing ring seriously affect the sealing performance. In order to prolong the service life of the hydraulic system, the bionic self-lubricating samples were prepared by filling SnAgCu and Ti 3 C 2 T x (SA...

Description
Summary:Heavy loads and fatigue wear of the contact areas between the hydraulic cylinder block and the sealing ring seriously affect the sealing performance. In order to prolong the service life of the hydraulic system, the bionic self-lubricating samples were prepared by filling SnAgCu and Ti 3 C 2 T x (SACT) into surface biomimetic textures, and the effect of wear frequency on the tribological properties of the samples was tested. Tribological properties were tested using a multifunction tribometer, the counter pairs were 42CrMo steel and polyurethane, respectively. Compared with smooth 42CrMo, bionic self-lubricating samples were easier to form smooth continuous worn surface at the appropriate frequency (5 Hz). Meanwhile, the average friction coefficient, wear loss, equivalent noise pressure level and noise intensity are minimum.
