PLANT FOR TESTING OF MATERIALS ON ABRASION WEAR Russian patent published in 2015 - IPC G01N3/56 

FIELD: testing equipment.

SUBSTANCE: plant comprises a base on which a rotary drive, a vertical shaft, a counterbody in the form of a flat ring with an abrasive mass on its surface, a sample holder mounted on the loading mechanism, and loads are mounted. The sample holder consists of two copper current-conducting plates electrically isolated from each other, connected to a power source. The ring is fixed on the drum with the ability of their rotation around the vertical shaft fixedly mounted on the base. Under the ring there is an electric heater in the form of a band of material with high electrical resistance, the ends of which are connected to the two copper ring buses arranged on the surface of the drum and electrically insulated from it. The ring buses are in sliding contact with the fixed current-conducting units connected to the current source, and the ring and the electric heater are located in the heat-insulating casing.

EFFECT: expanding the technological capabilities and improvement of reliability of the test results.
