Tribolayer - lubricant additives protecting against wear

摘要

Lubricants with suitable EP/AW additives reduce wear in rolling bearings and other machine elements subject to mixed friction. The effect of such additives depends on the conditions existing on the interacting surfaces. The aim of the tests described in the following was to determine the additives' reactivity under various kinds of motion. For this purpose, several surface-active additives were tested under motion conditions such as oscillating-sliding, oscillating-rolling-sliding and continuously sliding. As a result, strengths and weaknesses of additive groups under the tested contact conditions and the extent to which the test benches used are suitable for the evaluation of additives were identified.
