Abstract  

The tribological characteristics of T2/QCr0.5 rubbing pairs under the load of sine shock pulse and in the electrical current of various intensities, which simulated working conditions of the pantograph-wire system used in electrical railway, were examined on the pin-on-disc friction and wear tester of HST100.The results show that the electrical current is the important effect factor on tribological properties with electrical current, friction coefficient and wear rate increase with current intensity whereas the tendency is slow up with the further increasing of electrical current. The most wear form is adhesive wear, arc erosion and plastic deformation.

Key words:  dynamic load      current-carrying      tribological characteristics      friction coefficient      wear rate      adhesive wear      arc erosion      plastic deformation
