Vibroacoustic Study of Abrasive Wear of Multilayered Sliding Bearings

Abstract

The article substantiates consistent patterns of wear at the example of microcutting materials in sliding bearings in dependence to grain sizes of abrasive cloths and hardness of bearing layers received with the use of vibroacoustic diagnostics and the method of artificial bases (MAB) in testing on the SMC-2 frictional machine. These patterns can be helpful for the assessment of quality and selection of materials for products [1,2], selection of the friction model [3], and selection of abrasive cloths for the diagnostics of the latter and assessment of the running-in period for the top coating.
