采用球-盘摩擦磨损试验机，在控制湿度和氧气浓度的条件下，研究了湿度对氮化碳（CNx）在氮气（N2）气氛中摩擦性能的影响。结果表明，当O2浓度低于100 ppm时，通过将空气湿度从40%RH降低到0%RH，CNx/CNx和Si 3 N4 /CNx复合材料在N2气氛中的摩擦系数从0.1降低到0.01。此外，实验证实了CNx/CNx在N2气体气氛中的低摩擦稳定性。CNx/CNx摩擦副在99.9%的氮气条件下和2%或更低的相对湿度下提供了0.01的低且稳定的摩擦系数。
The effect of humidity on friction properties of carbon nitride (CNx) in nitrogen (N2 ) atmosphere were investigated by using a ball-on-disk tribo-tester in atmospheres with controlled humidity and oxygen concentration. It was concluded that friction coefficient in the combination of CNx/CNx and Si3 N4 /CNx in N2 gas atmosphere were reduced from the order of 0.1 to 0.01 by decreasing of humidity from 40% RH to 0% RH when the O2 concentration is kept below 100 ppm. Further, stability of low friction of CNx/CNx in N2 gas atmosphere was confirmed experimentally. The frictional pair of CNx/CNx provided low and a stable friction coefficient of 0.01 in 99.9% nitrogen gas condition under low relative humidity of 2% or less.Copyright © 2005 by ASME
