Investigating Lubrication Mechanisms for Silicon Nitride Sliding on Steel: A Multifaceted Study

Electric Motors (EMs) containing lubricated bearings must adhere to a variety of operational specifications and related microenvironments.Lubricate products need to perform under these circumstances.The wear and friction of silicon nitride (〖Si〗_3 N_4) sliding over toughened chrome steel (52100) were used to measure the tribological effectiveness of three commercially available EM lubricates.The EM lubricates that were examined and comparable viscosity ratings; however, they differed in the proportions of lithium or poly-urea thickener to mineral or synthetic base oil (BO).A variety of surface roughness (SR) levels and temperatures were measured to observe behaviour under various lubrication regimes.The results made possible to compare commercially available solutions directly across a range of application-relevant standards and the analysis techniques created as a foundation for upcoming research on the efficiency of EM lubricate.
