Abstract
One of the tribological tests for the evaluation of friction properties is introduced in this paper. The test, named \“Block-on-Ring”, is in accordance with the standard ASTM G-77 and in ŠKODA VÝZKUM Ltd. is realized on the VRS-3 renovated apparatus. The measurement is as follows: the flat surface of the sample is pressed against the cylindrical surface of a rotating wheel of the rotor material. Arbitrary oil is fed to the material contact surface and the increasing temperature is detected using a thermocouple. The friction force is recorded using the strain-gauge dynamometer. The test is performed in a number of periods and always after one expiration time the wear track formed in the sample is measured and evaluated. The final results are the summary of the partial results of the long-standing tests and are used for the preliminary detection of the friction behavior of individual material couples. Keywords: friction force, coefficient of friction, block-on-ring, ASTM G-77, wear.
