3018 Surface modification for sliding surface under lubrication with vegetable oils

Abstract

As for the vegetable oil, the application to the lubricant is expected as a material with low negative environmental impacts. However, because a lubrication performance is inferior to a conventional lubricant, the surface modification of sliding surface is needed for the 100% vegetable oil. The lubricity of the vegetable oil for several hard thin films, which are used as wear resistance materials, were examined. It reports on the result of considering suitable surface modification for the vegetable oil lubricating system.
