针对目前广泛用在金属热模锻中的石墨型润滑剂存在的污染环境和难以清理等问题,以无机层状氮化物和硬脂酸盐为主要固体润滑材料,得到系列非石墨型润滑剂,并对其润滑性能和润滑机理进行了研究。结果表明,4种系列润滑剂中,以无机层状氮化物配以复合硬脂酸盐类为主要成分的热模锻润滑剂具备最优良的悬浮性、成膜性,并且润滑性能与石墨型润滑剂相当,清理容易。目前,该新型非石墨型润滑剂可以在一定范围内替代石墨型润滑剂,是一种环保型润滑剂。
Aiming at the problems such as the pollution environment and difficult to clean up of the graphite type lubricants, which are widely used in metal hot forging, the series of non-graphite lubricants are obtained by using inorganic layered nitrides and stearates as the main solid lubricating materials, And its lubrication performance and lubrication mechanism were studied. The results showed that the hot-swaged lubricant with inorganic layered nitrides and composite stearates as the main components among the four series of lubricants possessed the best suspensibility and film-forming property, and the lubricity was comparable with that of graphite The lubricant is quite easy to clean. At present, the new non-graphite lubricant can replace graphite-based lubricant in a certain range and is an environment-friendly lubricant.
