Cr―Mo―N coating was prepared by magnetron sputtering, and its crystallinity and phase structure were analysed by X‐ray diffraction. The tribological properties of the coating separately lubricated with L‐P106 ionic liquid was compared with poly‐alpha‐olefin (PAO) and PAO‐containing MoDTP and ZnDTP additives with a ball‐on‐disc reciprocal friction and wear tester. It was found that the tribological properties of as‐prepared Cr―Mo―N coating vary with varying lubricant systems. Namely, the results indicated that the L‐P106 has better friction‐reducing and wear resistance properties than that of MoDTC and ZnDTP. The analyses indicated that Cr―Mo―N coatings and lubrication films can be considered as a solid–liquid duplex lubricating systems. Copyright © 2014 John Wiley & Sons, Ltd.
