    Abstract

    Larger carbides inherent in high-alloy steels can initiate surface peeling failures and cause other raceway distress which affects bearing performance under thin lubrication film operating conditions. They can also contribute to the microstructural alteration in conventional subsurface rolling contact fatigue. Carburizing low-carbon, high-alloy bearing steel produces fine carbides comparable to low-alloy steels.
