SAMPLE FOR FRICTION COEFFICIENT DETERMINATION Russian patent published in 2009 - IPC G01N19/02 

FIELD: physics.

SUBSTANCE: sample for determination of friction coefficient and its components is executed with hemispherical effective area, supplied by the hollow cylinder which diameter is equal to diameter of the hemisphere, the data unit of axial effort, force-measuring device, the hemisphere is supplied by axis, semicylinder is mounted on axis and one end face interreacts with hemisphere end face, and the data unit of axial effort is mounted coaxially to the cylinder, interreacts with its other end face, thus the sample is mounted on the explored plate forming uniform magnetic contour with magnetic circuit, between them there is adjustable backlash and, the hollow cylinder and explored plate are joined to the power supply, thus the axis is joined to the radiant of pulsing axial loading, and the explored plate is mounted on isolation support. In addition for featured above the sample the radiant of pulsing axial loading can be executed in the form of electromagnetic exciting coil.

EFFECT: increase of measurement accuracy of the molecular frictional force component of various materials in contact to any medium at activity of exterior actions in the form of magnetic field, electric current and pulsing component of tractive force.
