摘　　要：稳定性是评价液体磁性磨具性能的重要指标之一,其对液体磁性磨具在机械光整加工领域的商业应用与推广有着重要影响。为提高液体磁性磨具稳定性,依据液体磁性磨具中固相颗粒表面特性,提出了利用聚乙二醇(PEG)改性的方法。通过以聚乙二醇(PEG)添加量作为控制变量进行实验分析,发现聚乙二醇(PEG)的添加量对磨具稳定性有显著影响,并从微观角度讨论了聚乙二醇(PEG)添加量对固相颗粒间相互作用力的影响规律。研究成果对液体磁性磨具的配制具有一定的指导和借鉴意义。Stability is one of the important criteria for evaluating the properties of liquid magnetic abrasive, and it has significant effect on the business application and popularization of liquid magnetic abrasive in the field of mechanical finishing processing. In order to improve the stability of liquid magnetic abrasive, based on properties of the solid particles in the liquid magnetic abra- sive, put forward a solution to improve its stability by adding polyethylene glycol. Through experimental analysis,it is obvious that the effects of the content of polyethylene glycol on the stability of liquid magnetic abrasive. According to force analysis of a single particle, discussed the influence of the content of polyethylene glycol on the interaction force between solid particles. The research result is of guidance and reference for confecting liquid magnetic abrasive.
