Characterization and Anti-friction Behaviors of FeS Coating

The FeS solid lubrication coating with 500μm thick was prepared by a sol-gel method on the 1045 steel. XRD was used to detect the coating phase structures and SEM equipped with EDX was utilized to observe and analyze the morphologies and energy spectrum of the coating's surface and worn scars. The friction and wear tests show that the coating possesses good properties of anti-friction and wear-resistance. Because the thickness of the coating is much thick, the friction behavior only happens within the coating. So the steel substrate is kept away from wear.
