Abstract:
The friction and wear properties of amorphous carbon nitride (aCNx) coatings in water lubrication were reviewed. The influences of mating materials and tribological variables such as normal load and sliding speed on the friction and wear properties of the aCNx coatings were analyzed. It was indicated that the specific wear rate of the aCNx coatings was related to the hydration reaction of mating materials with water. If the mating materials were easily hydrated, the specific wear rate of aCNx coatings was low. The wa ter lubricated properties of the a-CNx coatings were better in comparison to the aC coatings. The aCNx/Si based non oxide ceramics tribo pairs exhibited the lowest friction coefficient and wear rate. To describe their friction and wear proper ties at the normal loads of 3—15 N and the sliding speeds of 0.05—0.5 m/s, the wear-mechanism maps for the aCNx/SiC (Si3N4) tribo pairs in water were developed.
