DEVICE FOR TESTING MATERIALS FOR DYNAMIC AND ABRASIVE WEAR Russian patent published in 2023 - IPC G01N3/34 G01N3/56 

FIELD: testing equipment.

SUBSTANCE devices for testing metals and alloys, as well as composite materials and coatings for resistance to dynamic and abrasive wear with a loose abrasive. The device contains an impact mechanism, including a striker and weights, a test sample fixed in the striker, a drive with a cam that provides the rise and fall of the striker, a dispenser for supplying abrasive mass. The device additionally contains a drum with cells for the abrasive mass, which performs periodic rotational sliding with a given step over the plate, synchronized by means of an additional cam, ratchet mechanism, levers, chain and gear drives with the striker with the sample falling so that the supply of the abrasive mass from the dispenser, removal waste mass into the bunker and the impact of the sample on the abrasive mass is carried out during the stop of the drum.

EFFECT: increased efficiency of testing materials for dynamic and abrasive wear with an abrasive mass.
