Abstract
A lubricant composition includes a base lubricant and a plurality of lubricant additive molecules. Each lubricant additive molecule includes a surface active group attractable to a target surface, and a carbon containing component connected to the surface active group, for providing a carbon source to form a carbon film on the target surface. A method for in situ forming of a carbon film using the lubricant composition, includes adding the lubricant composition into a target machine such that the lubricant composition is in contact with a target surface of the target machine, and operating the target machine to cause a temperature and a pressure at the target surface so that the carbon containing component is unraveled thereon to form a carbon film on the target surface during the operation.
