Abstract This work aimed to develop an efficient lubricant for physical vapor-deposited TiN coatings on steel by adding cyclopropane-carboxylic acid (CPCa) to PAO4 base oil to enhance boundary lubrication. Results showed that an ultralow coefficient of friction (0.008) and wear rate (7.0 × 10-8 mm3/N∙m) were obtained for the steel/TiN sliding contact using PAO4+2.5 wt % CPCa oil due to the in situ formation of a carbon-based lubricating tribofilm during the sliding process.
