Paper Title
Surface Response of Oil and Grease based Lubrication for Railway Application

Abstract
Numerous attempts have been made to make lubricant work more efficiently to decrease lubricant consumption and minimize wear and tear in machines. In this work, five types of nanomaterials are used to prepare nanolubricants in oil and grease mode. These nanoparticles are molybdenum disulfide, boron nitride, boric acid, copper, and kaolin. Paraffin oil is used as a base lubricant to disperse these nanoparticles. Further, the effect of friction properties on the steel substrate is evaluated against the sliding ball. Two distinct frictional behavior is tested, first under the effect of oil and second nanomaterials-based grease. The functional friction property of prepared lab grease is compared with commercial grease. Results show that molybdenum disulfide in oil and as particle grease performs well compared to other nanomaterials. The results are beneficial for the various types of rail applications such as elastic rail clips, switch expansion joint, rail joint, liner contact, etc., for providing lubrication.
