XPS characterization of tribo-layer formation on the steel lubricated with crude and epoxidized jatropha oil under boundary lubrication

The composition of the tribo-layer formed during sliding of steel in the presence of crude jatropha oil (CJO) and epoxidized jatropha oil (EJO) under boundary lubricant application was investigated using energy-dispersive X-ray and X-ray photo spectroscopy analyses. Utilizing four ball method accord...
