Study of Dry Sliding Friction and Wear Characteristic of High-Speed Steel/ Ti6Al4V Alloy under Direct Steady Magnetic Field
The influence of DC steady magnetic field on dry-sliding friction and wear characteristics of friction pair of high-speed steel (HSS) ring / Ti6Al4V pin is studied by use of improved MPV-1500 type under normal temperature. It is shown that the wear loss of ferromagnetic materials can be decreased by applying a steady magnetic field. Under the load of 250N and the friction velocity of 0.6m/s, the wear loss of the sample HSS ring keeps decreasing along with the enhancement of magnetic field intensity, and in the scope of 64mT-160mT, the average friction coefficient becomes smaller and smaller. Magnetic field can accelerate debris refinement. The wear mechanism covers oxidative wear and adhesive wear mainly.
