摘　　要：本文采用以生坯增强剂、脱模润滑剂、压制润滑剂为基本单元的组合润滑剂,从压制成形角度来探索润滑剂组合和添加量,对SUS304L不锈钢粉末的压制性、流动性和成形性的影响。结果表明,选用合适的润滑剂配比,对生坯密度、流动性、表面粗糙度和生坯强度有一定的改善作用,并得出适合粉末冶金不锈钢的较为合理的润滑剂选用方案。In this paper,the effects of different combinations and additions of lubricants on the compressibility,fluidity and formability of SUS304L stainless steel mixed powder were studied by using the combination lubricants of green reinforce,ejection lubricant and pressing lubricant as basic units in compaction. The results show that the green density,fluidity,surface roughness and green strength can be improved by choosing the proper lubricant ratio,a reasonable lubricant selection scheme for powder metallurgy stainless steel is obtained.
