Method for determining the coefficient of friction of antifriction interfaces using Amsler-type friction machines

Research of Tribological Features of Steel Surface by Creating Mineral Coatings

“…Figure 5 shows that the value of the coefficient of volumetric wear of an aluminum oxide toroid during rotation with discs with certain types of mineral coatings (Nos. 2,4,9,10) is less than 1,2х10 -9 mm 3 /Nm, which is significantly less than volumetric wear rate when rotating with uncoated discs (4-7)х10 -8 mm 3 /Nm. That is, the degree of wear of the alumina toroid conjugated to disks made of X12Cr13 steel with certain types of mineral coatings during rotation in water was at the level of the detection limit and therefore cannot be accurately quantified in this experiment.…”

“…-SMT-2 friction machine, being a modification of the Amsler friction machine (a schematic diagram is shown in different works, for example [9,10]), is intended for materials testing for friction and wear during rolling, sliding and sliding rolling. The friction machine is equipped with devices for calibrating its power systems, temperature measurements in the range of 20 ... 150 ° C, as well as for testing elements of model tribosystems in a liquid medium; -Electronic scales НТР-120СТ with a Tuning Fork sensor, weighing range from 0.01 g to 120 g with a resolution of not more than 0.0001 g, the calibration division value is not less than 0.001 g and accuracy class according to GOST 24104-2001 (State standard of the Russian Federation) special (I).…”
