Abstract

Soft coatings are used extensively in industry for contact friction reduction, particularly during the running-in period. A numerical model is developed for contact and lubrication analysis of some soft coating coated bearings in mixed fluid lubrication. The model is applied to determine oil film thickness, contact pressure, and the friction coefficient of the coated bearings in contact with a hard journal surface. The contact of tin-coated 339 Al-Si alloy bearings with case hardened steel is analyzed using the developed model.
