Study of Dry Sliding Friction and Wear Characteristic of High-Speed Steel / 40CrMoA Steel under Direct Steady Magnetic Field

Abstract:

The influence of DC steady magnetic field on dry-sliding Friction and wear characteristics of friction pair of high-speed steel (HSS) ring and 40CrMoA pin is studied by use of improved MPV-1500 type Friction and wear tester under normal temperature. Experiments show that, The wear loss of both HSS ring and 40CrMoA pin decreases gradually, along with the enhancement of the magnetic field intensity, under the load of 250N and the friction velocity of 0.6m/s; The wear loss of the sample HSS ring keeps low comparing with that of the sample 40CrMoA steel pin; The trend of friction coefficients decreases quickly and then slowly; Magnetic field can accelerate oxidization; Oxidation and adhesion occur mainly in friction surface.
