本文对Fe-Mo-MoS_2系材料进行了研究,并考察了该系材料中Fe/Mo比对性能的影响。结果表明,该系材料在摩擦状态下具有较好的减摩性能。在实际PV值高达200～300kg.m/cm~2。S时,摩擦系数均<0.1,磨损率为10~(-4)～10~(-5)m~3/m数量级。材料磨损率随Fe/Mo比增加而提高。用该材料加工成轴套在某机上进行初步台架试验(轴承PV值150kg.m/cm~2。S,工作温度200℃)表明,用该材料制成的轴承可以代替原用高温油脂润滑滚针轴承,轴承运转正常(其使用寿命有待考核)。
In this paper, Fe-Mo-MoS 2 series materials were studied, and the effects of Fe / Mo ratio on the properties of the series were investigated. The results show that the Department of the friction material in the state has good anti-friction properties. In the actual PV value up to 200 ~ 300kg.m / cm ~ 2. S, the friction coefficient is less than 0.1 and the wear rate is about 10 ~ (-4) ~ 10 ~ (-5) m ~ 3 / m. Material wear rate increases with increasing Fe / Mo ratio. With the material processed into a sleeve on a preliminary bench test (bearing PV value 150kg.m / cm ~ 2.S, operating temperature 200 ℃) shows that the bearings made of this material can replace the original high-temperature grease lubrication Needle bearing, bearing normal operation (its service life to be assessed).
