The effects of pre-corrosion, water and detergent contamination in Shell Turbo 32 (T32) mineral oil on rolling contact fatigue (RCF) life of rollers were experimentally investigated using a home-made ball-on-roller tester. The tested roller samples were analyzed by a scanning electron microscope (SEM) and an energy dispersive spectrum (EDS). The results show that the fatigue life of the rollers is reduced by all test conditions where the negative effect is enhanced with increasing the pre-corrosion time, from surfactant detergent to water contamination and to alkaline detergent. Microscopic analysis indicates that spalls on the rolling contact track are mainly surface initiated.
Key words: Rolling contact / fatigue / additives / corrosive
