1. A pin-on-disk type in-situ current-carrying friction testing system, comprising:
a pin-on-disk type friction pair, wherein the pin-on-disk type friction pair comprises a disk specimen arranged horizontally, and a pin specimen arranged vertically;
a clamping mechanism used to clamp the pin specimen;
an axial force loading mechanism used to push the pin specimen to move vertically;
a rotating power mechanism used to drive the disk specimen and the pin specimen to rotate relatively;
a force measuring mechanism used to measure a force between the disk specimen and the pin specimen;
a support platform used to support the disk specimen;
a current loading mechanism used to load a current to a contact surface between the disk specimen and the pin specimen, wherein the current loading mechanism comprises a conductive terminal, and the conductive terminal abuts against an annular sidewall of the disk specimen to guide a current in the disk specimen to move along a horizontal direction; and
a magnetic field generating unit used to generate a magnetic field;
wherein when the pin specimen and the disk specimen rotate relatively, the pin specimen, the conductive terminal, and the magnetic field are relatively stationary, and the current in the disk specimen flowing along the horizontal direction generates an Ampere force facing the support platform under the action of the magnetic field.
