FIELD: machine building.
SUBSTANCE: counter sample is rotated at a constant speed and by the counter sample a slot is cut in the sample in the zone of tribological contact at constant load up to the pre-set depth, thus the stability of test parameters is provided. The diameter of the counter sample D is selected from the condition D = (10÷50)h, where h is the sample width.
EFFECT: possibility to speed up the test process, simplify measurement of wear level and obtaining of reliable results while testing for wear resistance at rigid type of wear of sample material in dry friction conditions.
