Abstract
Various methods for the acceleration of Rolling Contact Fatigue (RCF) tests of M50 steel and hybrid M50-Si3N4 bearing systems were explored. The acceleration methods investigated were high Hertzian contact stress, toughening or pre-denting the rolling element surface, lubricant contaminated with Arizona Test Dust, lubricant contaminated with fine Al2O3 particles, and thermally degraded lubricant. The advantages and disadvantages of each method were analyzed and compared. Weibull analysis was performed on all-steel and hybrid systems in order to observe how each behaves under the various acceleration conditions. The results of the Weibull analyses will be reported in a subsequent paper. Structural changes were analyzed using conventional techniques such as scanning electron microscopy, optical microscopy and surface profilometry, as well as novel techniques such as atomic force microscopy.
