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