A series of different non-graphite type lubricants which were based by inorganic layered nitride and stearic acid salt as the main solid lubricating materials were prepared for the problems of environment pollution and the difficulty of cleaning residue caused by using graphite lubricant which was now widely used in metal hot forging, and their lubrication performance and lubrication mechanism were also studied. The results show that new kind of hot forging lubricants mainly based with inorganic layered nitride and composite stearic acid salt has the best suspension and film-forming ability. Its lubricating performance is considerable with graphite lubricant and is easily to clean up. At present, the new kind of non-graphite-based lubricant is a kind of environmental friendly lubricant and can replace graphite lubricant in a certain range.
